Title Characterizing Supersonic Gas Jet-based Beam Profile Monitors
Abstract The next gen­er­a­tion of high power, high in­ten­sity ac­cel­er­a­tors re­quires non-in­va­sive di­ag­nos­tics, par­tic­u­larly beam pro­file mon­i­tors. Resid­ual gas-based di­ag­nos­tics such as ion­iza­tion beam pro­file or beam in­duced flu­o­res­cence mon­i­tors have been used to re­place com­monly used scin­til­lat­ing screens. At the Cock­croft In­sti­tute an al­ter­na­tive tech­nique using a su­per­sonic gas jet, shaped into a 45o cur­tain screen, was de­vel­oped. It has al­ready demon­strated its su­pe­rior per­for­mance in terms of res­o­lu­tion and sig­nal-to-noise ratio in com­par­i­son with resid­ual gas mon­i­tors in ex­per­i­men­tal stud­ies. The per­for­mance of this type of mon­i­tor de­pends on the achiev­able jet ho­mo­gene­ity and qual­ity. Using a mov­able vac­uum gauge as a scan­ner, the dy­namic char­ac­ter­is­tics of the jet are stud­ied. In this paper we also give an analy­sis of the res­o­lu­tion for this mon­i­tor in de­tail from the the­ory and ion drift sim­u­la­tion.
