Vacuum Control and Gas Handling for COMPASS To kamak

Thi s paper is aimed at creating a vacuum and a gas handling subsystem. The new vacuum and the gas handling subsystem was developed at IPP/Prague after the COMPASS tokamak reinstallation. It was necessary to build a system which can operate 24/7 and be fully autonomous. A firmware programmed in the C programming language controls devices connected to the vacuum and the gas handling subsystem. The firmware is programmed at dsPIC r Microchip r embedded at a board assembled at IST Lisbon. The vacuum and the ga s handling are connected through fiber optics to a server computer and can be controlled remotely through a workstation situated at the control room.
