  An X-ray de­tec­tor is being de­vel­oped for di­ag­nos­tic mea­sure­ment and mon­i­tor­ing of the Drift Tube LINAC (DTL) at the Los Alamos Neu­tron Sci­ence Cen­ter (LAN­SCE) at Los Alamos Na­tional Lab. The de­tec­tor will con­sist of a row of x-ray spec­trom­e­ters ad­ja­cent to the DTL that will mea­sure the spec­trum of X-rays re­sult­ing from bremsstrahlung of elec­trons cre­ated in vac­uum by the RF. Each spec­trom­e­ter will mon­i­tor a spe­cific gap be­tween drift tubes, and will con­sist of an array of scin­til­lat­ing crys­tals cou­pled to SiPMs read out with cus­tom-built elec­tron­ics. The spec­trom­e­ter is de­signed with one LYSO and three NaI crys­tals. The LYSO pro­vides a tagged gamma source with three peaks that are used for cal­i­bra­tion of the NaI. A pro­to­type of the spec­trom­e­ter was tested at the LAN­SCE DTL to val­i­date the fea­si­bil­ity of mea­sur­ing gamma spec­tra and per­form­ing self-cal­i­bra­tion in situ. A sum­mary of test re­sults with the LAN­SCE pro­to­type will be pre­sented, along with a de­tec­tor sys­tem de­sign that aims to be mod­u­lar and in­ex­pen­sive across all mod­ules in the DTL. Plans for fu­ture de­vel­op­ment will be pre­sented as well.
