	A new 25 kV 2 ms 50 Hz extraction voltage power supply has been developed for the high performance H-minus ion source for the Front End Test Stand at the Rutherford Appleton Laboratory. The power supply has been designed to fit in a single 19 inch rack and has a modular design for easy maintenance. This paper details the design and performance of the power supply and extracted beam currents.

	The Front End Test Stand (FETS) under construction at RAL is a demonstrator for the front end systems of a future high power proton linac. Possible applications include a linac upgrade for the ISIS spallation neutron source, new future neutron sources, accelerator driven sub-critical systems, a neutrino factory etc. Designed to deliver a 60mA H-minus beam at 3MeV with a 10% duty factor, FETS consists of a high brightness ion source, magnetic low energy beam transport (LEBT), 4-vane 324MHz radio frequency quadrupole, medium energy beam transport (MEBT) containing a high speed beam chopper and non-destructive photo-detachment diagnostics. This paper describes the current status of the project and future plans.
