Abstract
Abstract
We present a detector-emulation method for developing,
optimizing, and testing front-end electronics for particle detectors
under realistic experimental conditions. The method is capable of
reproducing bipolar signals shape and amplitude, rates, pileup, and
radiation backgrounds. By controlling the different components of
the experimental environment, the method allows for the assessment
of their individual and combined effects, which is difficult to
achieve in test beam or experiment environment.
The technique emulates the output current of AC coupled detector
terminals for an experimental environment of interest, by combining
a sequence of recorded or simulated signal waveforms. Voltage
waveforms produced with off the shelf arbitrary waveform generators
are converted to current by a simple circuit, which also accounts
for the characteristic capacitance of the detector, and injected
into the front-end electronics. We demonstrate the technique by
applying it in the optimization and characterization of the
front-end electronics of the sTGC detector for the
ATLAS experiment.
