Di­ver­si­fied Tech­nolo­gies, Inc.(DTI) has de­liv­ered a fully solid state Klystron Power Sup­ply for the ISIS Front End Test Stand to Ruther­ford Ap­ple­ton Lab­o­ra­to­ry in the UK. The new pulsed power sup­ply drives a Toshi­ba E3740A klystron in prepa­ra­tion for con­struc­tion of a sys­tem to demon­strate high qual­i­ty in­tense chopped beams. DTI's sys­tem rep­re­sents a sig­nif­i­cant ad­vance in sol­id-state high power ac­cel­er­a­tor tech­nol­o­gy based upon a hard switch de­vel­oped for the US De­part­ment of En­er­gy (DOE) to meet sim­i­lar re­quire­ments for the In­ter­na­tion­al Lin­ear Col­lid­er(ILC). The sys­tem in­cludes two 220 kW switch­ing power sup­plies, a 110 kV solid state hard switch pulse mod­u­la­tor, mod anode and fil­a­ment power sup­plies, klystron fault pro­tec­tion, and in­ter­faces to the ISIS con­trols. This paper will ad­dress the de­sign and con­struc­tion of the KPS sys­tem, as well as test re­sults from the in­stal­la­tion at RAL in May 2009.
