The Op­ti­cal Sto­chas­tic Cool­ing (OSC) ex­per­i­ment at Fer­mi­lab’s IOTA stor­age ring uses two un­du­la­tors to cool the beam over many turns. The ra­di­a­tion emit­ted by elec­trons in the first un­du­la­tor is de­layed and im­aged in the sec­ond un­du­la­tor where it ap­plies a cor­rec­tive en­ergy kick on the elec­trons. Im­per­fec­tions in the man­u­fac­tur­ing of the delay plates can lead to a source of error. This paper pre­sents the ex­per­i­men­tal char­ac­ter­i­za­tion of the ab­solute thick­ness of these delay plates using an in­ter­fer­o­met­ric tech­nique. The mea­sured "thick­ness maps" are im­ple­mented in the Syn­chro­tron Ra­di­a­tion Work­shop (SRW) pro­gram to as­sess their im­pact on the de­layed ra­di­a­tion pulse.

A proof-of-prin­ci­ple op­ti­cal-sto­chas­tic cool­ing (OSC) ex­per­i­ment is cur­rently in its com­mis­sion­ing phase at the Fer­mi­lab’s IOTA ring. In sup­port of this ex­per­i­ment, we re­cently im­ple­mented an OSC el­e­ment in the EL­E­GANT track­ing pro­gram. The model, based on a semi-an­a­lytic de­scrip­tion of OSC [*], sup­ports the sim­u­la­tion of a large num­ber of macropar­ti­cles (104-106) over many turns (106). This paper show­cases the sim­u­la­tion ca­pa­bil­i­ties to in­ves­ti­gate the beam dy­nam­ics in the pres­ence of cool­ing (or self-in­ter­act­ing ra­di­a­tion field in gen­eral) and quan­tify the im­pact of var­i­ous sources of error (e.g. trans­verse and phase jit­ter), guide data analy­sis.
