Schottky noise detector used to pick up the fluctuations with a sensitive spectrum analyzer allows a non-destructive and precise measurement of several parameters, like momentum distribution, tune, transverse emittance and chromaticity. Here, two kinds of Schottky detectors with the high sensitivity and their measurements are presented.
Capacitive Schottky pickup on CSRm
Resonant Schottky pickup on CSRe (cooperated with GSI)
