Kontrola vakua a plynového systému pro tokamak COMPASS
Janky, F. ; Pereira, T.V. ; Santos, B.A. ; Hron, Martin
This 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 dsPICr Microchip r embedded at a board assembled at IST Lisbon. The vacuum and the gas handling are connected through fiber optics to a server computer and can be controlled remotely through a workstation situated at the control room
Komunikační protokol pro kontrolu polohy a tvaru plazmatu tokamaku COMPASS

The Compass tokamak, reinstalled at IPP Prague, will have a new digital plasma position and shape control system. Development of a communication protocol is necessary for the connection between the energetics devices built by CKD company and the operator - either human or computer together. The present work is focused on development of such communication protocol. Human operator can send a request for status of energetics, time synchronization, counting errors, etc. through communication protocol. Predefined currents for individual power supplies will be send through the communication protocol. In the future this system will be replaced by feedback control system integrated in CODAC (Control Data Acquisition and Communication system).
