Design and operation of a beam probe system for T(i) : Measurements at TEXTOR
A beam probe diagnostic using 35 kV helium atoms has been designed to determine the local ion temperature by application of the small angle Rutherford scattering. Both the active beamline and the time-of-flight analyser can be moved on supporting ball rail systems in two directions and adjusted to different scattering angles, providing a great versatility to the diagnostic experiment. Electrical engineering has created technical solutions to avoid damage from grid discharges of the ion source. This aim is achieved by proper grounding and electromagnetic shielding to keep power supplies and environment free from distortions.
