THPD03	PLC Controlled Search & Secure Safety Interlock System for Accelerator	PLC, controls, electron, 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.

	Indus-1 and Indus-2, the Synchrotron Radiation Source (SRS) facilities at RRCAT Indore are national facilities and being operated on round the clock basis to provide synchrotron radiations to users as well as carrying out machine studies. Both of these accelerators are widely distributed systems and employ many sub systems for their operation. These sub-systems are also made up of heterogeneous type of hardware and software modules. To keep the whole system up and running, the faults & failures encountered during machine operations are attended at site and all observations and rectifications information are to be recorded electronically by the crew members. FLogbook has been conceived and developed to meet such needs. This web based software operates in the Intranet environment over a three tier architecture. It mainly uses JavaServer Pages (JSP), JavaBeans and SQL databases for designing its building blocks. Using relational database, the package supports logging, e-mailing, searching & commenting the faults of various sub systems. This paper explains the salient features of FLogbook and also briefly describes the architectural design of the complete package.

	M.A. Nozdrin, N. Balalykin, V. Minashkin, V.Y. Schegolev, G. Shirkov, G.V. Trubnikov JINR, Dubna, Moscow Region, Russia
	Due to Joint Institute for Nuclear Research participation in ILC collaboration, e-linac accelerator test-bench is being created in Laboratory of high energy physics of JINR. The bench is designed for several goals: accelerating structures and diagnostics testing, photoinjector prototype creation and investigation, radiation resistance studies of different materials etc. In addition, several proposals of FEL creation on the basis of the e-linac exist. Current setup, results of the test-bench control systems evolution since 2009 and future plans are presented. The most important updates include radiation control system calibration, verification and installation and an upgrade of the video control system.

	We have developed a car-borne survey system named as KURAMA (Kyoto University RAdiation MApping system) for the establishment of air dose rate map in Fukushima and surrounding area as a response to the nuclear accident at TEPCO Fukushima Daiichi Nuclear Power Plant on March 11, 2011. KURAMA is developed with LabVIEW. The monitoring data tagged by GPS location data are shared with remote servers over 3G mobile network, then processed by servers for a real time plot on Google Earth and other various purposes. A CompactRIO-based KURAMA-II is developed for the autonomous operation in public vehicles. More than a hundred of KURAMA and KURAMA-II now serves for the drawing up the radiation map in the East Japan by Japanese government. The outline and present status of KURAMA and KURAMA-II are introduced.

FRCC04	Digital Pulse Processing Techniques for High Resolution Amplitude Measurement of Radiation Detector	target, shielding	279
	P. Singhai, P. Dhara, A. Roy VECC, Kolkata, India S. Chatterjee HITK, Kolkata, India
	The digital pulse processing techniques for high resolution amplitude measurement of radiation detector pulse is an effective replacement of expensive and bulky analog processing as the digital domain offers higher channel density and at the same time it is cheaper. We have demonstrated a prototype digital setup with high-speed sampling ADC with sampling frequency of 80-125 MHz followed by series of IIR filters for pulse shaping in a trigger-less acquisition mode. The IIR filters, peak detection algorithm and the data write-out logic was written on VHDL and implemented on FPGA. We used CAMAC as the read out platform. In conjunction with the full hardware implementation we also used a mixed-platform with VME digitizer card with raw-sample read out using C code. The rationale behind this mixed platform is to test out various filter algorithms quickly on C and also to benchmark the performance of the chip level ADCs against the standard commercial digitizer in terms of noise or resolution. The paper describes implementation of both the methods with performance obtained in both the methods.
