WEPD09	Fast Data Acquisition System for Booster Supplies Readback	controls, booster, synchrotron, electron	18
	K. Saifee, A. Chauhan, P. Fatnani, P. Gothwal, C.P. Navathe RRCAT, Indore (M.P.), India
	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.

WEPD13	Serial Multiplexed Based Data Acquisition and Control System	controls, GUI, status, power-supply	29
	N.C. Patel, C.K. Chavda, K.G. Patel IPR, Bhat, Gandhinagar, India
	Data acquisition and control system consist of analog to digital converter, digital to analog converter, timer, counter, pulse generation, digital input / output etc depending upon requirement. All the components of the system must communicate with personal computer (PC) for data and control signal transmission using any one of the communication protocol like Serial, Parallel, USB, and GPIB etc. Serial communication is advantageous over other protocol like long distance data transmission, less number of physical connection, ease of implementation etc. The developed serial multiplexed system can control different module like ADC (for a small analog channel density, moderate sampling rate and local on-board memory) module, DAC (for controlling pressure valve, biasing voltage etc) module, DIO ( for system status monitoring and status control) module, Timer card ( for generating delayed pulse for triggering and synchronizing with other system) using single serial port. A LabVIEW based GUI program is developed for the individual communication of each module.

	There are many Non Destructive Technique used in science and industry to evaluate the properties of a material, component or system without causing damage Infrared Thermography is one of them. Different types of IR thermo-graphy are used for different purpose. We are using hot and cold-water flow IR Thermography method to evaluate the Performance of Plasma Facing Components (PFC) for Divertor Mock-up. The Set-up is designed in such a way that hot and Called Water can flow in both direction inside mockup, like left to right and right to Left using electric motor. Eight numbers of Solenoid Valves have been used for selection of Water Flow Direction, thermo-couples for temperature measurement of water, IR camera to take the images and many others devices. Which needs a very good and versatile DAC system. We have developed a DAC system usingμcontroller and LabView for the acquisition of various parameters and controlling & synchronization of other system. Development of DAC is described in this paper

	S. Kulkarni, P. V. Bhagwat, J.A. Gore, A.K. Gupta, S. Kailas BARC, Mumbai, India
	A new program (GUI) for testing CAMAC modules (CAMAC ADC, DAC, Input Gate, Output Register) is developed using Labview and dynamic link libraries (DLLs). On start-up, the program initializes the CAMAC Controller via PCI bus interface, thus enabling communication with CAMAC modules. It can test CAMAC modules through different controls like slider bars, buttons etc. and display status of individual channels with soft panel meters and LEDs. The GUI is extremely useful in troubleshooting hardware problems of CAMAC modules and also in developing new modules.

THCA04	An Update on ConSys Including a New LabVIEW FPGA Based LLRF System	controls, PLC, cavity, LLRF	97
	T. Worm, J.S. Nielsen ISA, Aarhus, Denmark
	ConSys, the Windows based control system for ASTRID and ASTRID2, is now a mature system, having been in operation for more than 15 years. All the standard programs (Console, plots, data logging, control setting store/restore etc.) are fully general and are configured through a database or file. ConSys is a standard publisher/subscriber system, where all nodes can act both as client and server. One very strong feature is the easy ability to make virtual devices (devices which do not depend on hardware directly, but combine hardware parameters.) For ASTRID2 a new LabVIEW based Low-Level RF system has been made. This system use a National Instruments NI-PCIe7852R DAQ card, which includes an on-board FPGA and are hosted in a standard PC. The fast (50 kHz) amplitude loop has been implemented on the FPGA, whereas the slower tuning and phase loops are implemented in the real-time system. An operator interface including live plots from the regulation loops are implemented in a host program on Windows. All three levels have been implemented with LabVIEW. The LLRF system is interfaced to ConSys through LabVIEW shared variables.

	Data storage is a primary issue in any research facility. In the EPICS middleware based accelerator community, Channel Archiver has been always considered the main reference. It works with Oracle and MySQL, probably the best well known relational databases. However, demanding requirements at minimum costs have fostered the development of a wide range of alternatives, like protocol buffers (SLAC), MSDPlus (Consorzio RFX), SciDB (BNL) or Hypertable (IFNF). This document launches a tool called HyperArchiver, which was firstly developed at IFNF (Italy) and eventually customised by ESS Bilbao (Spain). Based on a NoSQL database named Hypertable, it focuses on large data sets management with maximum scalability, reliability and performance. Besides the update and further customization made at ESS Bilbao, HyperArchiver is presented with a set of GUIs, in order to provide an easy use and integration with any general control system. A LabVIEW VI and two cross-platform PyQt GUIs for both Hypertable data retrieval and HyperArchiver control have been developed and successfully tested at ESS Bilbao.

	The Tango[1] control system framework contains the communication bus with the standard communication modes as well as the basic hardware access modules, GUI tools and development kits, services and bindings to commercial products to set up a control system. Tango was developed by several synchrotron light sources that have to support not only the accelerator complex but also a lot of experimental end stations. For synchrotron experiments we have to control the whole process from basic hardware access over data taking to data analysis. This paper describes in the first part the special features of Tango allowing flexible experiment control. The dynamic configuration, the rapid hardware interface development and the sequencing and scanning framework are some examples. The second part gives an overview of some packages developed in the Tango community for experiment control: A HKL library for diffraction computation and diffractometer control, a library to control 2D detectors and a data analysis workbench with workflow engine for on-line and off-line data analysis. These packages are not part of Tango and can be used with other control systems. [1] http://www.tango-controls.org/

	S. Guha, T.K. Bhaumik, C. Mallik, P.Y. Nabhiraj VECC, Kolkata, India
	ZigBee based wireless technology is used to provide a low cost, low power, secured, PAN solution for monitoring of parameters from several distributed vacuum pumping modules installed in the SCC injection line. The parameters include On-Off status of the modules, RPM of pump, input current and pressure reading of different vacuum gauges. The ZigBee stack is written in a simplified form so that each node can create a network and can join to any established network when powered on. End nodes can be replaced through a little modification in the firmware codes. End node consists of sensors, signal conditioning circuits, micro-controller and ZigBee Transceiver whereas the central node consists of micro-controller, Transceiver and UART interface. This paper highlights the future approach of utilizing this network for data acquisition related with environmental temperature, relative humidity, noise, water leakage from inaccessible areas of Cyclotron Vault, Pit, Basement and ECR Highbay for the ease of maintenance also demonstrate the development of an environment monitoring system powered by solar cells covering a wide area.

	A. Kasliwal, T.G. Pandit RRCAT, Indore (M.P.), India
	Funding: RRCAT, Indore, Department of Atomic Energy, Government of India This paper describes a distributed embedded system that uses a high performance mixed signal controller C8051F040 for its DAQ nodes and is based on CAN bus protocol for remote monitoring and controlling of various subsystems of 750 keV DC accelerator based irradiation facility at RRCAT, Indore. A PC with integrated PCI CAN card communicates with intelligent DAQ nodes over CAN bus and each node is interfaced with a subsystem. An opto- isolated SN65HVD230 CAN driver is interfaced between each node and physical bus. Remote frames and message prioritizing are used for efficient control. The PC application is developed using LabVIEW 8.6. The proposed system is more reliable and noise immune as compared to previously [1] used systems that initially used a centralized system based on C8051 controller. This was then upgraded [2] to a distributed system that used micro-controller AduC812 and communicated over RS485 link. The new system has been integrated and tested satisfactorily for its designed performance with test jigs that simulated the actual subsystems with a bus length of 75 meters. First the complete scheme of the system is presented, then the hardware and software designs are discussed. [1] A.

THPD44	The CS framework as a Control System for the HITRAP Facility at GSI	GUI, controls, ion, laser	219
	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.
