Analysis and calibration of the noise voltage between the damper plates used for beam diffusion during the crystal extraction experiment

The analogue noise signal produced by a WAVETEK function generator, which is used to excite one of the horizontal dampers BDH 21437 or BDH 21451 for blowing up the beam during the crystal extraction MDs, has been analysed to determine its r.m.s. value as a function of the selected attenuation. The i...

Descripción
Sumario:The analogue noise signal produced by a WAVETEK function generator, which is used to excite one of the horizontal dampers BDH 21437 or BDH 21451 for blowing up the beam during the crystal extraction MDs, has been analysed to determine its r.m.s. value as a function of the selected attenuation. The input/output characteristics of damper Nº 2 (BDH 21451) has been measured in order to calibrate the r.m.s. kicks (diffusion speed) which a particle experiences on its passage through the damper.
