The sta­tus of FEL-based Co­her­ent Elec­tron Cool­ing Proof-of-prin­ci­ple Ex­per­i­ment at BNL is pre­sented. The ex­per­i­men­tal set-up is com­prised of a 2 MeV CW SRF elec­tron gun and 20 MeV CW SRF linac and 8-m long he­li­cal FEL am­pli­fier. The sta­tus of the ac­cel­er­a­tor com­mis­sion­ing, and progress in the con­struc­tion of the he­li­cal un­du­la­tor at Bud­ker INP, is also re­ported

The Co­her­ent Elec­tron Cool­ing Proof-of-Prin­ci­ple ex­per­i­ment [*] based on an FEL is cur­rently under con­struc­tion in the RHIC tun­nel at BNL. Di­ag­nos­tics for the ex­per­i­men­tal ma­chine [**] are cur­rently being de­signed, built and in­stalled. This paper fo­cuses on the de­sign of the in­frared di­ag­nos­tic in­stru­men­ta­tion down­stream of the three tan­dem 2.8m long he­li­cal wig­gler sec­tions that will act on a 22MeV 68uA elec­tron beam co-prop­a­gat­ing with the 40GeV/u RHIC gold beam. The 14 um FEL ra­di­a­tion, or wig­gler light, will be ex­tracted from RHIC via a view­port in a down­stream DX mag­net cryo­stat and analysed by in­stru­men­ta­tion on a nearby op­tics bench. In­stru­ments con­cen­trat­ing on three pa­ra­me­ters, namely in­ten­sity, spec­tral con­tent, and trans­verse pro­file, will ex­tract in­for­ma­tion from the wig­gler light in an at­tempt to quan­tify the over­lap of the elec­tron and ion beams and act as an in­di­ca­tor of co­her­ent cool­ing.

The pur­pose of the Co­her­ent elec­tron Cool­ing Proof-of- Prin­ci­ple (CeC PoP) [1] ex­per­i­ment being de­signed at RHIC is to demon­strate lon­gi­tu­di­nal (en­ergy spread) cool­ing be­fore the ex­pected CD-2 for eRHIC. The scope of the ex­per­i­ment is to lon­gi­tu­di­nally cool a sin­gle bunch of 40 GeV/u gold ions in RHIC. The cool­ing fa­cil­ity will be in­stalled in­side the RHIC tun­nel in 3 phases. The sta­tus of the in­stru­men­ta­tion sys­tems planned for phase 1 com­mis­sion­ing ef­forts will be de­scribed. This paper will also de­scribe up­dates to the in­stru­men­ta­tion sys­tems pro­posed to meet the di­ag­nos­tics chal­lenges dur­ing the final phase of cool­ing com­mis­sion­ing [2]. These in­clude mea­sure­ments of beam in­ten­sity, emit­tance, en­ergy spread, bunch length, po­si­tion, and trans­verse align­ment of elec­tron and ion beams.
