The 70705 Photomultiplier Power Supply provides the highly regulated voltage needed for precision measurements with Oriel photomultiplier tubes (PMTs). Since the signal current varies as the 5th to 10th power of the supply voltage (depending on the PMT), stability of the voltage supply is vital. It is used to supply negative voltages to -2000 V, and has a positive ground. This facilitates connection of the output (anode) to our current measuring equipment.
