WEPD22	Post-Mortem Analysis of BPM-Interlock Triggered Beam Dumps at PETRA-III	GUI, controls, emittance, synchrotron	43
	G.K. Sahoo, K. Balewski, A. Kling DESY, Hamburg, Germany
	PETRA-III is a 3rd generation synchrotron light source dedicated to users at 14 beam lines with 30 instruments. This operates with several filling modes such as 60, 240 and 320 bunches with 100mA or 40 bunches with 80mA at a positron beam energy of 6 GeV. The horizontal beam emittance is 1nmrad while a coupling of 1% amounts to a vertical emittance of 10pmrad. During a user run unscheduled beam dumps triggered by Machine Protection System may occur. In many cases the reason can be identified but in some it remains undetected. Though the beam is lost some signature is left in the ring buffers of the 226 BPM electronics where last 16384 turns just before the dump are available for post-mortem analysis. Scrutinizing turn by turn orbits and the frequency spectrum measured at a BPM can improve understanding of such a beam loss and may help to increase the efficiency of operation by eliminating the sources. Here we discuss in detail the functionality of a Java GUI used to investigate the reasons for unwanted dumps. In particular, the most effective corrector method is applied to identify correctors that might have perturbed the golden orbit leading to violations of the interlock limits.

THIA03	The IUAC Tandem-LINAC Control System	controls, linac, GUI, monitoring	94
	A. Kumar, B.K. Sahu, K. Singh IUAC, New Delhi, India
	The 16MV Tandem Van de Graff accelerator at IUAC is one of the earliest machines to go for a PC based control system. The PDP11, supplied with it, was replaced by an IBM PC running DOS before the accelerator was commissioned in 1989. The present system, commissioned in 1997 to include the LINAC, runs on a network of PCs under the GNU/Linux operating system. We have followed a distributed approach by grouping the signals, around 1000 in total, based on the location. Each group is connected to a server computer, by hardware interfaces like CAMAC, VME and custom hardware. The signals connected to each server PC are handled by a server program and they are accessible to the outside world, over a TCP/IP network, using a unique identifier consisting of a Label, Function and Unit. The features like a user interface, monitoring for alarm conditions, data logging and partial automation are handled by several client programs, communicating to multiple servers to access the hardware. The communication is done by passing a message packet and waiting for the reply. The message consists of the unique signal identifier and commands for setting/reading analog and digital parameter values. The development of the control system also resulted in low cost equipment for science education[1]. It also helped further development of the control system by additions like client programs in Python language. This feature enabled accelerator users to write simple scripts for tasks like setting the LINAC resonator parameters based on calculations, writing routines for partial automation etc. The system is cost effective, scalable and simple. It has shown very high reliability and ease of use during the past two decades of operation. [1] http://expeyes.inhttp://expeyes.in

	D. Neidherr, D.H. Beck, H. Brand, F. Herfurth GSI, Darmstadt, Germany
	At the GSI accelerator complex in Darmstadt Germany the linear decelerator HITRAP is currently under commissioning. The aim is to provide highly charged ions up to bare uranium at cryogenic temperatures for various experiments as for instance tests of the theory of quantum electrodynamics. The ions are delivered with kinetic energies of about 4 MeV/u from GSIs experimental storage ring (ESR) and are slowed down in several steps until they are trapped and cooled down in a Penning trap. Whereas for the ESR as well as for the first sections of the linear decelerator the GSI accelerator control system is used the cooler trap as well as the subsequent transfer section to the experimental area are controlled with the LabVIEW based CS-framework developed at GSI. This framework is an object-oriented, event driven and multi-threaded framework with SCADA functionality, which is currently in use at many different experiments world-wide. For the HITRAP facility additional features like an online beam monitoring, realized with the integration of a LVOOP class capable of reading out IMAQ cameras, as well as a new GUI were implemented, which allows automatic scans of beam elements.

	A new timestamp and event distribution system for the upcoming FAIR facility is being developed at GSI. This timing system is based on White Rabbit[1], which is a fully deterministic Ethernet-based network for general data transfer and synchronization. White Rabbit is developed by CERN, GSI and other institutes as well as partners from industry based on Synchronous Ethernet and PTP. The main tasks of the FAIR timing system are time synchronization of more than 2000 nodes with nanosecond accuracy, distribution of timing messages and subsequent generation of real-time actions (interrupts, digital signals …) by the nodes of the timing system. This allows precise real-time control of the accelerator equipment according to the beam production schedule. Furthermore the timing system must support other accelerator systems like post-mortem and interlock. It also provides interfaces between the accelerator control system and experiments at FAIR. This contribution focuses on the design principles of the timing system, its integration with other components of the control system, the present status and the planned implementation. [1] J.

	P. Dhara, P. Maity, A. Roy, P.S. Roy, P. Singhai VECC, Kolkata, India
	The beam from K130 room temperature cyclotron is being extensively used for nuclear physics experiments for last three decades. The typical beam energy for the experiments is approximately 7-10MeV/nucleon for heavy ions and 8-20MeV/nucleon for light ions. The number of detectors used, may vary from one channel to few hundreds of detector channels. The proposed detector system for experiments with the superconducting cyclotron may have more than 1200 detector channels,and may be generating more than one million parameters per second. The VME and CAMAC based data acquisition system (DAQ) is being used to cater the experimental needs. The current system has been designed based on various commercially available modules in NIM, CAMAC and VME form factor. This type of setup becomes very complicated to maintain for large number of detectors. Alternatively, the distributed DAQ system based on embedded technology is proposed. The traditional analog processing may be replaced by digital filters based FPGA boards. This paper describes the design of current DAQ system and the status of the proposed scheme for distributed DAQ system with capability of handling heterogeneous detector systems.

The beam from K130 room temperature cyclotron is being extensively used for nuclear physics experiments for last three decades. The typical beam energy for the experiments is approximately 7-10MeV/nucleon for heavy ions and 8-20MeV/nucleon for light ions. The number of detectors used, may vary from one channel to few hundreds of detector channels. The proposed detector system for experiments with the superconducting cyclotron may have more than 1200 detector channels,and may be generating more than one million parameters per second. The VME and CAMAC based data acquisition system (DAQ) is being used to cater the experimental needs. The current system has been designed based on various commercially available modules in NIM, CAMAC and VME form factor. This type of setup becomes very complicated to maintain for large number of detectors. Alternatively, the distributed DAQ system based on embedded technology is proposed. The traditional analog processing may be replaced by digital filters based FPGA boards. This paper describes the design of current DAQ system and the status of the proposed scheme for distributed DAQ system with capability of handling heterogeneous detector systems.
