Title A Gas-filled Capillary Based Plasma Source for Wakefield Experiments
Abstract A plasma medium can be formed when a gas is dis­charged via an ap­plied high volt­age within a cap­il­lary tube. A high volt­age dis­charge based plasma source for plasma wake- field ac­cel­er­a­tion ex­per­i­ment is being de­vel­oped. De­sign con­sid­ered a glass cap­il­lary tube with var­i­ous inner radii. Glass was pre­ferred to sap­phire or quartz op­tions to ease the ma­chin­ing. Elec­trodes will be at­tached to the tube using a sealant re­sis­tant to high vac­uum con­di­tions and bak­ing at high tem­per­a­tures. Each elec­trode will be iso­lated from the neigh­bour­ing one using nuts or wash­ers from a ther­mo­plas­tic poly­mer in­su­la­tor ma­te­r­ial to pre­vent un­wanted spark­ing out­side of the tube. In this paper, gen­eral de­sign con­sid­er­a­tions and pos­si­ble work­ing points of this plasma source are pre­sented for a range of plasma den­si­ties from 1×1020 to 1×1022 m−3. Con­sid­er­a­tion was also given to plasma den­sity di­ag­nos­tic tech­niques due to crit­i­cal de­pen­dence of ac­cel­er­at­ing gra­di­ent on plasma den­sity.
