Electrostatic discharge detector

If a material can be made into both PC and PV devices, then PV devices are preferred because they have a better theoretical signal-to-noise value, simpler biasing, and more reliable prediction of responsivity and noise. PC detectors are less fragile physically and less sensitive to electrostatic discharge (ESD). For early detectors that was an important issue, but robust ESD protection is almost always included in modern commercial devices.

Fig. 4.36 Schematic of the reflective beam blocker setup. Ions are produced in a pulsed discharge and accelerated to 7 keV. A gold mirror is placed in the beam path to illuminate the fast moving ion packet with a 10 Hz IR laser pulse. A set of electrostatic electrodes is used to bump the ion beam over the reflective beam blocker. On the way to the ion detector the ion beam enters an electrostatic ion beam trap (EIBT) dedicated to photoelectron-photofragment coincidence (PPG) experiments [493]...
