WEPD11	Client Server Architecture Based Embedded Data Acquisition System on PC104	controls, status, GUI, monitoring	23
	J.J. Patel, P.K. Chattopadhyay, R. Jha, P. Kumari, R. Rajpal IPR, Bhat, Gandhinagar, India
	The data acquisition system is designed on embedded PC104 platform Single Board Computer (SBC) with running Windows XP Embedded operating system. This is a multi channel system which consists of 12 Bit, 10 MSPS Analog to Digital Converters with on board FIFO memory for each channel. The digital control and PC104 bus interface logic are implemented using Very High Speed Hardware Description Language (VHDL) on Complex Programmable Logic Device (CPLD). The system has provision of software, manual as well as isolated remote trigger option. The Client Server based application is developed using National Instrument CVI for remote continuous and single shot data acquisition for basic plasma physics experiments. The software application has features of remote settings of sampling rate, selection of operation mode, data analysis using plot and zoom features. The embedded hardware platform can be configured to be used in different way according to the physics experiment requirement by different top level software architecture. The system is tested for different physics experiments. The detailed hardware and software design, development and testing results will be discussed in the paper.

THPD05	Design and Analysis of Second Harmonics Modulator for DC Current Transformer	feedback, pick-up, controls, factory	145
	K.D. Joshi, K. Reju BARC, Mumbai, India
	DC Current Transformers (DCCT) are widely used in the world of particle accelerators. DCCT is a device which produces even harmonics, predominantly second harmonics corresponding to DC beam current flowing through two toroids. The second harmonics is detected by digital synchronous detector implemented in programmable logic. Current proportional to the detected second harmonic is passed through the toroids in a feedback loop such that the flux due to the DC beam current is cancelled by it. This feedback current is the measure of average beam current. The high permeability toroids, excitation and output windings are collectively called magnetic modulator, which is a key component of DCCT. Design and analysis of a second-harmonic magnetic modulator used as a detector for DC Current transformer for high resolution current measurement is presented.

FRCA04	Control System for BARC-TIFR Pelletron	controls, status, linac, ion	251
	S. Singh, J.A. Gore, S. Kulkarni, P. Singh BARC, Mumbai, India
	Pelletron is 14 MV tandem Accelerator operating from past 20 years. It was operating on DOS based control system. Its control system software and CAMAC controller hardware has been changed recently. Control system software is is a two layer software namely Scanner and operator console. First layer which runs at equipment interface layer interacts with all CAMAC crates acts a server , known as Scanner. Scanner is developed in LINUX and uses TCP/IP protocol suite for interaction with CAMAC and operator interface. Scanner uses shared memory to store machine's runtime data. Operator console is a Graphics interface software developed by using QT APIs. Operator interface is source code portable between MS windows and LInix.

FRCB03	RF Control System for 400 keV RFQ	controls, LLRF, cavity, monitoring	260
	G. Joshi, T. Ananthkrishnan, S.K. Bharade, P. M. Paresh, C.K. Pithawa, C.I. Sujo BARC, Trombay, Mumbai, India
	An RF control system has been developed for the 400 keV, 350 MHz RFQ coming up at BARC. This single cavity system consists of the functionalities of amplitude stabilization and frequency tracking for both continuous and pulsed mode of operation. The amplitude stabilization is implemented by modulating the attenuation across a fast modulator placed in the drive path. The frequency tracking is achieved by driving the FM port of a signal generator with a signal proportional to the phase shift across the resonator. The whole system is under computer control via CAMAC hardware. The paper describes the system architecture, housing & wiring of the system in a single instrumentation rack and development & testing of computer control.
