The Los Alamos Neu­tron Sci­ence Cen­ter’s (LAN­SCE) Ac­cel­er­a­tor Op­er­a­tions and Tech­nol­ogy di­vi­sion group ex­e­cuted a pro­ject that im­ple­mented a new ana­log front-end card (AFE) for their wire scan­ner’s Data Ac­qui­si­tion (DAQ) sys­tem. The AFE ac­com­mo­dates the sig­nal am­pli­fi­ca­tion and noise re­duc­tion needed to ac­quire es­sen­tial mea­sure­ment data for beam di­ag­nos­tics for the LAN­SCE ac­cel­er­a­tor. Wire Scan­ners are elec­tro-me­chan­i­cal beam in­ter­cep­tive de­vices that pro­vide cross-sec­tional beam pro­file mea­sure­ment data fit­ted to a Gauss­ian dis­tri­b­u­tion that pro­vides beam shape and po­si­tion in­for­ma­tion. The beam op­er­a­tors use the beam shape and po­si­tion in­for­ma­tion to ad­just pa­ra­me­ters such as ac­cel­er­a­tion, steer­ing and focus on de­liv­er­ing an op­ti­mized beam to all tar­gets. The pro­ject im­ple­mented soft­ware and hard­ware that elim­i­nated the de­pen­dency on legacy sys­tems and con­sol­i­dated var­i­ous AFE de­signs for di­ag­nos­tics sys­tems into a sin­gle de­sign with 11 gain set­tings rang­ing from 100 nA to 40 mA at 10 V full scale to ac­com­mo­date fu­ture ap­pli­ca­tions on other di­ag­nos­tic sys­tems.
