Abstract

The PIXE chamber of CBNM, designed for high flexibility in analytical conditions and high throughput of samples, is equipped with stepper motors to serve the various movable components in the chamber. A versatile motor controller was designed which steers all motors in the chamber, allows for a safety interlock system, and which can readily be expanded or adapted to more and other types of stepper motors if necessary. By interfacing this controller to a computer via the IEEE-488 protocol, it can be remotely controlled in order to automatise complete series of full analysis cycles. An integrated software package has been written, which combines the motor steering - including the necessary safety interlocks - with the control of all MCA functions under a single menu-oriented program. The modular design of the controller and the interfacing by standard IEEE-488 make it portable to other experiment environments.
