An immense advantage of EM 2 detectors is that—when calibrated properly—they are noiseless and single ion counting is possible. The essence of an EM is a serial connection of discrete metal plates ...
The R928 has a gain of 1.0 x 10 7 (10 million) at -1 kV supply voltage, so each dynode multiplies the amount of electrons by six, with a response time of 22 ns. PMTs are unsurprisingly not cheap, ...

The Series B and Series C high-voltage power supplies incorporate a dynode driver for use with side- or front-window photomultipliers like the 931A and the IP28. Series B supplies ...
