	The booster synchrotron at RRCAT is used to inject electron beam in Synchrotron Radiation Sources Indus-1 & Indus-2. The booster gets 20 MeV beam from Microtron, ramps up its energy to 450/550 MeV which is then extracted for injection in Indus-1/Indus-2. The ramping cycle repeats every second. For this, various magnet power supplies are fed with synchronous reference voltage & current waveforms and accordingly they feed the magnets with current waveforms of ~800 msec. A system was required to synchronously capture data of all power supplies to analyze changes on cycle to cycle basis. Global data acquisition system polling data at 1 Hz can't acquire sufficient points to do this. So a VME and PC based system has been developed for parallel and fast capture of data from 13 such power supplies. VME station has a CPU,13 ADC cards and one control card. User can select- permit to capture, start delay, samples and time interval between samples. Advantages are' Isolated, simultaneous capturing on 13-channels, capturing synchronized with an event and selectable capturing-rate and samples. It involved reconfiguring ADC boards, developing RTOS OS-9 Device Driver & programs for CPU Board and GUI for PC using LabVIEW.

WEPD34	A Low-Cost High-Performance Embedded Platform for Accelerator Controls	controls, laser, free-electron-laser, survey	68

	Over the last years the mobile and hand-held device market has seen a dramatic performance improvement of the microprocessors employed for these systems. As an interesting side effect, this brings the opportunity of adopting these microprocessors to build small low-cost embedded boards, featuring lots of processing power and input/output capabilities. Moreover, being capable of running a full featured operating system such as GNU/Linux, and even a control system toolkit such as Tango, these boards can also be used in control systems as front-end or embedded computers. In order to evaluate the feasibility of this idea, an activity has started at ELETTRA to select, evaluate and validate a commercial embedded device able to guarantee production grade reliability, competitive costs and an open source platform. The preliminary results of this work are presented.

	This paper presents current status and upgrade plan of a data-acquisition (DAQ) system for SACLA user experiments. The X-ray Free-Electron Laser facility in SPring-8, SACLA, has achieved first SASE lasing in June 2011, and has delivered X-ray laser beams to users from March 2012 [1]. For the user experiments at SACLA, a dedicated DAQ system has been developed. The DAQ system is currently capable to operate with maximum 10 sensors of multiport Charge-Coupled Device (MPCCD) for X-ray detection. With this configuration, the MPCCD generates 10 MBytes data per accelerator beam shot, which is equivalent to 5 Gbps data rate at 60 Hz beam repetition. During the first experimental period from March to July 2012, the DAQ system carried out 25 experimental proposals that covered atom, molecular and optical physics, ultrafast science, material science, and structure biology. In this paper, we present an overview of the DAQ system with special emphasis on the high-speed data cache, and data visualization by on-site PC clusters. An upgrade plan of the DAQ storage more than 3 PBytes and the on-line data-analysis with the off-site 10 PFlops supercomputer ("K computer") are also discussed. [1] T.

THIB04	Control System Interoperability, an Extreme Case: Merging DOOCS and TINE	controls, EPICS, target, status	115
	P. Duval, A. Aghababyan, O. Hensler, K. Rehlich DESY, Hamburg, Germany
	In controlling large facilities one is rarely able to manage all controllable elements via a common control system framework. When the standard framework must deal with numerous 'foreign' elements it is often worthwhile to adopt a new framework, rather than 'disguising' such components with a wrapper. The DOOCS[1] and TINE[2] control system frameworks fall into this scenario. Both systems have a device server oriented view, which made early mapping attempts (~2001) immediately successful. Transparent communication, however, is but a small (albeit important) part of the control system merger currently taking place. Both systems have well-established central services (e.g. archiving and alarms), and possess a general 'culture' which might dictate to a large extent how something is actually 'done'. The long term goal of the DOOCS/TINE merger is to be able to make use of any tool, from either the DOOCS or TINE toolbox, on any control system element. We report here on our progress to date, concentrating on the REGAE accelerator, and plans for the XFEL accelerator (to begin commissioning in 2015). [1] http://doocs.desy.de [2] http://tine.desy.de

THCC02	Controls Architecture for the Diagnostic Devices at the European XFEL	controls, diagnostics, monitoring, site	121
	O. Hensler DESY, Hamburg, Germany
	The X-ray laser is an 3.4-km-long facility which runs essentially underground and comprises three sites above ground. For controlling all diagnostic devices like toroids, BPMs or BLMs, it is planned to use the new MTCA.4 crate standard instead of VME. ATCA is an emerging standard from the Telecom Industry and adapted with the PICMG MTCA.4 branch for physics usage. The communication on the backplane utilizes the high speed serial PCIe communication plus precise clock lines and SATA interface. The MTCA.4 hardware supports hot-plug mechanism and remote monitoring and control via IPMI over Ethernet. Some of the diagnostics will be connected to 16Bit ADCs with up to 125Mhz sampling rate from Struck company or to an internal DESY development call DAMC2. The software architecture is based on the DOOCS control system known from the FLASH accelerator. The raw data from the ADCs will be read via DMA transfer by one server process. Then this raw data will distributed locally on the CPU using a message passing system based on the ØMQ project. The receiving server processes are calculating these data into engineering units then. Everything works in an event driven way.

THPD03	PLC Controlled Search & Secure Safety Interlock System for Accelerator	PLC, controls, radiation, high-voltage	142
	V. Sharma, S. Acharya, S. Gond, K.C. Mittal, R.N. Rajan BARC, Mumbai, India
	PLC based search and scram system is designed and commissioned to ensure the accelerator cell being free from any human occupancy before we start the accelerator. Search and Scram units which are controlled by PLC have been installed at different places inside the cell area. The operator of the accelerator has to clear all the units by pressing the secure button. Clearing each of the unit and pressing the button ensures that there is nobody left inside the cell after all the units are cleared. If someone remains trapped inside cell even after search and secure operation successfully performed, he can press any emergency button located on each of the Scram unit to switch off the accelerator immediately. The operation is time limited so if the operator fails to do the search operation in time, the entire system will get tripped and will require to the operator to do the entire operation again. This system generates HV ON enable signal. If any of the door is opened or Scram is pressed the HV supply switches off and radiation ceases off immediately. This system has the merit that it offers timing and sequence flexibility but retains the safety merit of hard wired circuit.

THPD04	Machine Throughput Improvement Achieved Using Innovative Control Technique	controls, PLC, linac, GUI	144
	V. Sharma, S. Acharya, K.C. Mittal BARC, Mumbai, India
	Funding: BARC, Mumbai A 10MeV, Electron beam, RF Linac is operational at EBC, Kharghar, Navi Mumbai. The beam output scans one meter length in a scan horn. The product under irradiation is placed in a conveyor trolley where trolley is one meter long and one meter gap between the trolleys. With the constant speed of 5mtrs/min operation of trolley, the dose utilization is 50% since the beam falls in the gap between the trolleys. We have modulated the speed as 5mtrs./min when trolley gap is under the beam and 0.1 mtrs./min when trolley is under the beam. This way the beam utilization for the irradiation goes up to 98% hence 48% rise in productivity. A 20kV 10KJ Electromagnetic machining (EMM) facility is developed by APPD/BARC. In this EMM facility a large value capacitor is charged by a DC supply to a constant voltage. This charged capacitor is then discharged using triggered spark gap into a coil to generate intense magnetic field. This magnetic field generates the eddy current into the job piece to do the forming. We have used a PLC based control system to control the machine.

THPD14	Status of the Migration of the S-DALINAC Accelerator Control System to EPICS	controls, EPICS, status, diagnostics	166
	C. Burandt, U. Bonnes, J. Enders, F. Hug, M. Konrad, N. Pietralla TU Darmstadt, Darmstadt, Germany
	Funding: Supported by DFG through CRC 634. The S-DALINAC is a recirculating superconducting electron LINAC which has been in operation for twenty years. The control system had been developed in-house and, while being moderately reliable, has become very hard to maintain and nearly impossible to adapt to new requirements. The replacement of the old analog low-level RF control system by a modern digital solution in 2010 became a primer for the introduction of an EPICS-based control system. Several important subsystems have been migrated since then, but the process has not been completed yet. This contribution overviews the current status of the new control system and developments planned for the future. Basic hardware aspects are described as well as client software and operator interfaces. The general network infrastructure has been restructured in context of the ongoing migration and is also presented.

PLC based search and scram system is designed and commissioned to ensure the accelerator cell being free from any human occupancy before we start the accelerator. Search and Scram units which are controlled by PLC have been installed at different places inside the cell area. The operator of the accelerator has to clear all the units by pressing the secure button. Clearing each of the unit and pressing the button ensures that there is nobody left inside the cell after all the units are cleared. If someone remains trapped inside cell even after search and secure operation successfully performed, he can press any emergency button located on each of the Scram unit to switch off the accelerator immediately. The operation is time limited so if the operator fails to do the search operation in time, the entire system will get tripped and will require to the operator to do the entire operation again. This system generates HV ON enable signal. If any of the door is opened or Scram is pressed the HV supply switches off and radiation ceases off immediately. This system has the merit that it offers timing and sequence flexibility but retains the safety merit of hard wired circuit.
