The char­ac­ter­i­za­tion of high in­ten­sity charged par­ti­cle beams in a min­i­mally in­ter­cep­tive, and non-de­struc­tive man­ner is per­formed using an ion­iza­tion di­ag­nos­tic. In this ap­pli­ca­tion, a neu­tral gas is tai­lored into a thin sheet, or cur­tain-like, dis­tri­b­u­tion at the in­ter­ac­tion point with an elec­tron beam. The elec­tron beam ion­izes the neu­tral gas in lo­cal­ized space, leav­ing a foot­print of the beam trans­verse dis­tri­b­u­tion. The ion cloud is sub­se­qe­untly im­aged with a se­ries of elec­tro­sta­tic lenses to a de­tec­tor plane. The re­sul­tant image is used in a re­con­struc­tion al­go­rithm to re­con­struct the beam pro­file at the in­ter­ac­tion point. In this paper, we pre­sent progress on the de­vel­op­ment of this di­ag­nos­tic for the char­ac­ter­i­za­tion of high charge, 10GeV elec­tron beams with small trans­verse dis­tri­b­u­tions.
