A wireless control system based on MODBUS protocol has been developed for operation of the High Temperature Superconducting ECR ion source, PKDELIS [1], LEBT and associated systems on a 200 kV high voltage platform. The isolation channels for the two high voltage platforms are implemented using ISM band wireless channel. A server for organization wide connectivity over Ethernet for access from the main IUAC control room has been implemented. History features and an intuitive GUI interface is provided. The system has been in regular use and has proven to be rugged and reliable.

| Currently the 10MeV Linac is being used for different research applications and industrial use. The control system in operation was developed using CAMAC based DAS, backed by Hard-wired Interlock System. It is proposed to replace the CAMAC system with a state-of-the-art indigenously developed PLC that is verified to the level of a Class IB computer-based system used in nuclear power plants. A PLC node comprises of two VME bus based CPU boards (PowerPC MPC7447, 600MHz) working in redundant mode. The Inputs and Outputs are common to both CPUs. The intelligent I/O boards are hot swappable. The PLC hardware and software has undergone rigorous verification and validation. A user-friendly development environment is provided to the process engineer for building the application using pre-defined function blocks. The LCS developed using PLC is to be used for operating the Linac irradiation facility, remotely as well as locally in a fail-safe mode, with sequential start-up and sequential shut-down. Apart from system status monitoring, data archiving, alarm generation and setpoint adjustments, it shall monitor the important parameters and trip the GM HV, KM HV and EG PS on fault conditions. | |||

| THPD21 | Testing of Inductive Output Tube based RF Amplifier for 650 MHz SRF Cavities | controls, PLC, EPICS, high-voltage | 187 |
|
|||
| A 650 MHz IOT based RF amplifier has been developed in VECC. It can be used to power several cavity modules in high energy high current proton linear accelerator to be built for ADSS programme in India and in Project-X at Fermilab, USA. The IOT based amplifier requires different powers supplies, water cooling and forced air cooling for its operation. A Programmable Logic Controller (PLC) based interlocks has been incorporated to take care of systematic on/off of the power supplies and driver amplifier, water flow, air flow and other interlocks for the safe operation of the RF System. In addition to that EPICS based RF operating console and data logging/monitoring system has been added. | |||

| THPD26 | Integrated Control System for LEHIPA | controls, proton, DTL, ion-source | 192 |
|
|||
| The Low Energy High Intensity Proton Accelerator (LEHIPA) is a 20 MeV 30 mA proton accelerator which will be achieved in multiple stages. LEHIPA consists of several sub systems/devices located at different positions of the beam path which includes ION source , RF Power , RF Protection Interlock System, Low Conductivity Water plant, Low Level RF control Systems, Vacuum System, Beam Diagnostics & Beam Line Devices. All these subsystems have their own local control systems (LCS) which will coordinate the operation of the corresponding subsystem. The control system for LEHIPA is thus being designed as a Distributed Control System with different teams developing each LCS. The control system will assist the operator to achieve a beam of desired characteristics by interacting with various sub systems of the accelerator in a seamless manner,protect the various parts machine by generating the necessary interlocks ,keep track of various parameters monitored periodically by suitably archiving them, alarms annunciation and trouble shoot from the control room. This paper describes approach to system design of ICS. | |||
| THPD45 | Overview of Control System for 30MeV RF Source | controls, linac, klystron, gun | 222 |
|
|||
| Control system for RF source of 30 MeV, 3 kW RF Linac for neutron generation is being developed. The system consists of two 15 MeV linac structures, each powered independently with klystron rated for 7.5 MW(pk)/7.5 kW(avg). Two klystron modulators of 160kV, 110A, 7usec and 250Hz feed pulsed power into the klystron, which produces RF power at 2856 MHz. The klystrons will be driven by low power RF driver amplifiers programmed for matching phase, frequency and power into the linac. Both the driver amplifiers are controlled through RS-232 Protocol. The HV pulsing and RF drive for the klystron has been interlocked with water flow, arc detector, SF6 gas pressure etc. The control system is designed using Real time embedded controller, where pulses for synchronization are being generated in FPGA. Most of the power supplies like electromagnet, HVDC, etc. are on RS-232 protocol. These power supplies are controlled via suitable RS-232 to Ethernet converter. State machine topology is being used to design the logic. The database for logging data is developed in SQL. This paper describes the details of the software implementation and hardware used to realize the control of the RF power source. | |||
