	The National Synchrotron Light Source II is under construction at Brookhaven National Laboratory, Upton, USA. NSLS-II consists of linac, transport lines, booster synchrotron and the storage ring. The main features of booster are 1 or 2 Hz cycle and beam energy ramp from 200 MeV up to 3 GeV in 300 msec. EPICS is chosen as a base for the NSLS-II Control System. The booster control system covers all parts of the facility such as power supplies, timing system, diagnostics, vacuum system and many others. Each part includes a set of various electronic devices and a lot of parameters which shall be fully defined for the control system software. This paper considers an approach proposed for defining some equipment of the NSLS-II Booster. It provides a description of different entities of the facility in a uniform way. This information is used to generate configuration files for EPICS IOCs. The main goal of this approach is to put information in one place and elimination of data duplication. Also this approach simplifies configuration and modification of the description and makes it more clear and easily usable by engineers and operators.

	SESAME is a synchrotron light source under installation located in Allan, Jordan. It consists of 2.5 GeV storage-ring, a 800 MeV Booster-Synchrotron and a 22 MeV Microtron as Pre-Injector. SESAME succeeded to get the first beam from Microtron, the booster is expected to be commissioned by the end of 2013, the storage-ring by the end of 2015 and the first beam-lines in 2016. This paper presents building of control systems of SEAME booster. EPICS is the main control-software tool and EDM for building GUIs which is being replaced by CSS. PLCs are used mainly for the interlocks in the vacuum system and power-supplies of the magnets, and in diagnostics for florescent screens and camera- switches. Soft IOCs are used for different serial devices (e.g. vacuum gauge controllers) through Moxa terminal servers and Booster power supplies through Ethernet connection. Libera Electron modules with EPICS tools (IOCs and GUIs) from Diamond Light Source are used for beam position monitoring. The timing System consists of one EVG and three EVR cards from Micro Research Finland (MRF). A distributed version control repository using Git is used at SESAME to track development of the control subsystems.

	The booster control system is an integral part of the NSLS-II control system and is developed under EPICS. The booster control system includes six IBM Systems x3250 M3 and four VME3100 controllers connected via Gigabit Ethernet. These computers provide running IOCs for power supplies control, timing, beam diagnostics and interlocks. Also cPCI ADCs located in cPCI crate are used for beam diagnostics. Front-end electronics for vacuum control and interlocks are Allen-Bradley programmable logic controllers and I/O devices. Timing system is based on use of Micro-Research Finland Oy products: EVR 230RF and PMC EVR. Power supplies control use BNL developed set of a Power Supply Interface (PSI) which is located close to power supplies and a Power Supply Controller (PSC) which is connected to a front-end computer via 100 Mbit Ethernet. Each PSI is connected to its PSC via fiber-optic link. High Level Applications developed in Control System Studio and python run in Operator Consoles located in the Control Room.

	When operating a multicomponent system, it is always necessary to observe the state of a whole installation as well as of its components. Tracking data is essential to perform tuning and troubleshooting, so records of a work process generally have to be kept. As any other machine, the NSLS-II booster should have an implementation of monitoring and archiving schemes as a part of the control system. Because of the booster being a facility with a cyclical operation mode, there were additional challenges when designing and developing monitoring and archiving tools. Thorough analysis of available infrastructure and current approaches to monitoring and archiving was conducted to take into account additional needs that come from booster special characteristics. A software extension for values present in the control system allowed to track the state of booster subsystems and to perform an advanced archiving with multiple warning levels. Time stamping and data collecting strategies were developed as a part of monitoring scheme in order to preserve and recover read-backs and settings as consistent data sets. This paper describes relevant solutions incorporated in the booster control system.

TUPPC082	DSP Design Using System Generator	FPGA, hardware, simulation, interface	770
	J.M. Koch ESRF, Grenoble, France
	When designing a real time control system, a fast data transfer between the different pieces of hardware must be guaranteed since synchronization and determinism have to be respected. One efficient solution to cope with these constraints is to embed the data collection, the signal-processing and the driving of the acting devices in FPGAs. Although this solution imposes that the whole design is being developed for an FPGA, in pure hardware, it is possible to open the part dedicated to the signal processing to non HDL (Hardware Description Language) specialists; the choice has been made here to develop this part under System Generator, in Simulink. Another challenge in such system design is the integration of real time models on already pre-configured hardware platforms. This paper describes with few examples how to interface such hardware with HDL System Generator control systems blocks. The advantages of Simulink for the simulation phase of the design as well as the possibility to introduce models dedicated to the tests are also presented.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. The eRHIC electron beams will be damaging both directly and as a result of synchrotron radiation. The machine protection and abort systems will be designed to prevent any equipment damage from the electron beams. In this paper we will review the requirements for the machine protection systems and the plans we have put into place to better evaluate the failure probabilities, beam abort systems designs, and overall machine protection systems designs. The machine protection systems will include a beam permit system that has inputs from loss monitors, power supplies, superconducting RF monitors, vacuum chamber heating monitors, water temperature, quench detectors, access controls systems, vacuum monitors, and longer term beam lifetime or slow loss monitors. There are three systems associated with the machine protection and beam abort systems; the beam permit link, the abort kicker systems, and the beam dumps. We describe the requirements for these systems and present our current plans for how to meet the requirements.

THMIB07	Fast Orbit Feedback Control in Mode Space	controls, feedback, synchrotron, electron	1082
	S. Gayadeen, S. Duncan University of Oxford, Oxford, United Kingdom M.T. Heron Diamond, Oxfordshire, United Kingdom
	This paper describes the design and implementation of fast orbit feedback control in mode space. Using a Singular Value Decomposition (SVD) of the response matrix, each singular value can be associated with a spatial mode and enhanced feedback performance can be achieved by applying different controller dynamics to each spatial mode. By considering the disturbance spectrum across both dynamic and spatial frequencies, controller dynamics for each mode can be selected. Most orbit feedback systems apply only different gains to each mode however; mode space control gives greater flexibility in control design and can lead to enhanced disturbance suppression. Mode space control was implemented on the Booster synchrotron at Diamond Light Source, operated in stored beam mode. Implementation and performance of the mode space controller are presented.

	The NSLS-II booster is a full-energy synchrotron with the range from 200 MeV up to 3 GeV. The ramping cycle is 1 second. A set of electronics developed in BNL fro the NSLS-II project was modified for the booster Power Supplies (PSs) control. The set includes Power Supply Interface which is located close to a power supply and a Power Supply Controller (PSC) which is connected to EPICS IOC running in a front-end computer via 100 Mbit Ethernet. A table of 10k setpoints uploaded to the memory of PSC defines a behavior of a PS in the machine cycle. A special software is implemented in IOC to provide a smooth shape of the ramping waveform in the case of the waveform change. A Ramp Manager (RM) high level application is developed in python to provide an easy change, compare, copy the ramping waveforms, and upload them to process variables. The RM provides check of a waveform derivative, manual adjusting of the waveform in graph and text format, and includes all specific features of the booster PSs control. This paper describes software for the booster ramp handling.

	The Advanced Light Source (ALS) timing system upgrade introduces a complete replacement of both the hardware and the technology used to drive the timing of the accelerator. The implementation of a new strategy for the booster injection and extraction mechanisms is conceptually similar to the one in place today, but fundamentally different due to the replacement of the technology. Here we describe some of the building blocks of this new implementation as well as an example of how the system can be configured to provide timing for injection and extraction of the ALS booster.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. The Electron Beam Ion Source (EBIS) began operating as a pre-injector in the C-AD RHIC accelerator complex in 2010. Historically, C-AD RHIC pre-injectors, like the 200MeV Linac, have had largely independent timing systems that receive a minimal number of triggers from the central C-AD timing system to synchronize the injection process. The EBIS timing system is much more closely integrated into central C-AD timing, with all EBIS machine cycles included in the master supercycle that coordinates the interoperation of C-AD accelerators. The integrated timing approach allows better coordination of pre-injector activities with other activities in the C-AD complex. Independent pre-injector operation, however, must also be supported by the EBIS timing system. This paper describes the design of the EBIS timing system and evaluates experience in operational management of EBIS timing.

	Funding: Work supported by Brookhaven Science Associates, LLC under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. The NASA Space Radiation Laboratory (NSRL) at BNL uses many different beams to do experiments associated with evaluating the possible risks to astronauts in space environments. This facility became operational in 2003 and operates from the AGS Booster synchrotron. In order to simulate the space radiation environment some of these experiments need to make use of beams of various energies. To simulate solar flare events, we implemented the Solar Particle Simulator in 2005. This system put in modifications to the accelerator controls to allow beam energies to be changed automatically, enabling target samples to be irradiated with many energies of the same type of ion, without having to make use of degraders. To simulate Galactic Cosmic events, they need to also be able to automatically change the ions used to irradiate a single sample. This project aims to allow NSRL to change ions as well as beam energies within a very short period of time. To do this requires modifications to existing controls as well as building new controls for a laser ion source. In this paper we describe NSRL, our plans to implement the Galactic Cosmic Event Simulator, and the status of the laser ion source.

The Electron Beam Ion Source (EBIS) began operating as a pre-injector in the C-AD RHIC accelerator complex in 2010. Historically, C-AD RHIC pre-injectors, like the 200MeV Linac, have had largely independent timing systems that receive a minimal number of triggers from the central C-AD timing system to synchronize the injection process. The EBIS timing system is much more closely integrated into central C-AD timing, with all EBIS machine cycles included in the master supercycle that coordinates the interoperation of C-AD accelerators. The integrated timing approach allows better coordination of pre-injector activities with other activities in the C-AD complex. Independent pre-injector operation, however, must also be supported by the EBIS timing system. This paper describes the design of the EBIS timing system and evaluates experience in operational management of EBIS timing.

The NASA Space Radiation Laboratory (NSRL) at BNL uses many different beams to do experiments associated with evaluating the possible risks to astronauts in space environments. This facility became operational in 2003 and operates from the AGS Booster synchrotron. In order to simulate the space radiation environment some of these experiments need to make use of beams of various energies. To simulate solar flare events, we implemented the Solar Particle Simulator in 2005. This system put in modifications to the accelerator controls to allow beam energies to be changed automatically, enabling target samples to be irradiated with many energies of the same type of ion, without having to make use of degraders. To simulate Galactic Cosmic events, they need to also be able to automatically change the ions used to irradiate a single sample. This project aims to allow NSRL to change ions as well as beam energies within a very short period of time. To do this requires modifications to existing controls as well as building new controls for a laser ion source. In this paper we describe NSRL, our plans to implement the Galactic Cosmic Event Simulator, and the status of the laser ion source.
