  Trans­verse pro­file di­ag­nos­tics for high-in­ten­sity beams re­quire so­lu­tions that are non-in­ter­cept­ing and sin­gle-shot. In this paper, we de­scribe a gas-sheet ion­iza­tion di­ag­nos­tic that em­ploys a pre­ci­sion-shaped, neu­tral gas jet. As the high-in­ten­sity beam passes through the gas sheet, neu­tral par­ti­cles are ion­ized. The ion­iza­tion prod­ucts are trans­ported and im­aged on a de­tec­tor. A neural-net­work based re­con­struc­tion al­go­rithm, trained on sim­u­la­tion data, then out­puts the ini­tial trans­verse con­di­tions of the beam prior to ion­iza­tion. The di­ag­nos­tic is also adapt­able to image the pho­tons from re­com­bi­na­tion. Pre­lim­i­nary tests at low en­ergy are pre­sented to char­ac­ter­ize the work­ing prin­ci­ple of the in­stru­ment, in­clud­ing com­par­isons to ex­ist­ing di­ag­nos­tics. The re­sults are pa­ram­e­trized as a func­tion of beam charge, spot size, and bunch length.
