Computer Control Division is primarily involved in development, maintenance and upgradation of Control, Data Acquisition & Diagnostic Systems for Room Temperature Cyclotron (RTC), Superconducting Cyclotron (SCC), Medical Cyclotron, Electron LINAC and various experimental facilities of the centre. The development of control and data acquisition systems for the Magnetic Field Mapping (MFM) of SCC, RTC and upcoming Medical Cyclotron are the other important activities of this division. The division is also engaged in developing State-of-the-art Instruments e.g. vacuum gauge controller, nano-ammeter, RF power meter, alarm annunciator, etc. and various EPICS software tools.
The main activity of the section is the development of Experimental Physics & Industrial Control System (EPICS) based state-of-the-art distributed control system for Room Temperature Cyclotron (RTC) and Superconducting Cyclotron (SCC). This involves development of Supervisory Control System comprising of Operator Interface (OPI) and Input Output Controller (IOC) for the following subsystems of the cyclotrons.
High current power supplies for various magnets
High voltage power supplies
PIG ion source
Beam diagnostic system
Cyclotron control console
vacuum system
LCW system
Cyclotron status monitoring facility
The section is also responsible for day-to-day maintenance and upgradation of control hardware and software of the above control system. The testing and implementation of latest tools and technologies of EPICS to control system is being done on regular basis. Beside this, the following ARM based EPICS embedded modules are indigenously developed.
Beam Diagnostics Controller,
Vacuum gauge controller,
Alarm Annunciator
Power supply controller
The following EPICS Software Tools have also been developed.
CA Activex components for OPI,
EPICS MySQL Archiver for control system data logging
web based E-Log for operator log
The development of the following electronics/ controller/ position encoder readout electronics, jig movement controller and software for control and data acquisition for MFM system is an important activity of this section. The indigenously developed MFM system for SCC is capable of acquiring 106 field data point in around 180 minutes without human intervention.
The section indigenously develops the following precision instruments as import substitution.
nano ammter
RF power meter
charge integrator
SiPM based phase measurement with latest technology and connectivity
The section is also entrusted with the development of control system for prototype medical cyclotron.
