Ra­di­a­Beam is de­vel­op­ing a Bunch Shape Mon­i­tor (BSM) with im­proved per­for­mance that in­cor­po­rates three major in­no­va­tions. First, the col­lec­tion ef­fi­ciency is im-proved by adding a fo­cus­ing field be­tween the wire and the en­trance slit. Sec­ond, a new de­sign of an RF de­flec­tor im­proves beam lin­ear­ity. Fi­nally, the de­sign is aug­mented with both a mov­able wire and a mi­crowave de­flect­ing cav­ity to add func­tion­al­ity and en­able mea­sur­ing the trans­verse pro­file as a wire scan­ner. In this paper, we pre-sent the de­sign of the BSM and its sub-sys­tems.

The SNS Beam Test Fa­cil­ity re­search pro­gram is fo­cused de­tailed stud­ies of beam dis­tri­b­u­tions for medium-en­ergy ion beams, with the goal of re­con­struct­ing re­al­is­tic 6D bunch dis­tri­b­u­tions to en­able halo pre­dic­tion. For com­plete char­ac­ter­i­za­tion of the ini­tial dis­tri­b­u­tion, scan time scales ex­po­nen­tially with scan di­men­sion. Cur­rently, a full 6D mea­sure­ment with ~10 points across most di­men­sions re­quires 30 hours. How­ever, mea­sure­ment of the 5D dis­tri­b­u­tion f(x, x’,y,y’,w) can be done very rapidly using a hy­brid slit/screen method. This ap­proach re­quires ~4 hours to ob­tain at least 32 points/di­men­sion, with very high res­o­lu­tion (0.5 keV) in the en­ergy dis­tri­b­u­tion. This pre­sen­ta­tion re­ports on the ap­proach and re­sults for 5D char­ac­ter­i­za­tion of the ini­tial RFQ-formed bunch. This in­cludes higher-res­o­lu­tion views of pre­vi­ously re­ported trans­verse-lon­gi­tu­di­nal de­pen­dence and ad­di­tional in­ter­plane de­pen­den­cies that were not pre­vi­ously re­ported.
