Our laboratory tests photomultiplier tubes (PMTs) and silicon photomultipliers (SiPMs) for noble-liquid detector development. Pulsed LED illumination, a signal generator and waveform readout are used to study sensor response and check the readout chain.

Pulsed-light tests and PMT readout

A signal generator controls the LED pulses and provides an external trigger. Oscilloscope measurements support signal inspection and comparisons between PMT anode and dynode readout.

SiPM LED calibration

LED calibration measurements are also used to examine SiPM response and evaluate the associated readout electronics.
