Abstract Cryo­genic regimes of op­er­a­tion are, for var­i­ous rea­sons, highly ad­van­ta­geous for nor­mal con­duct­ing ac­cel­er­a­tor struc­tures. Liq­uid cryo­gen-based sys­tems are costly to im­ple­ment and main­tain. As a re­sult, de­vel­op­ing cryo­genic test fa­cil­i­ties at a smaller more cost ef­fec­tive scale using cryo-cool­ers is at­trac­tive. Be­fore real im­ple­men­ta­tions of a cryo-cooler based beam­line, a sig­nif­i­cant amount of in­for­ma­tion is nec­es­sary re­gard­ing the be­hav­ior and prop­er­ties of var­i­ous com­po­nents and ma­te­ri­als at cryo­genic tem­per­a­tures. Find­ing this in­for­ma­tion lack­ing for our par­tic­u­lar beam­line case and by ex­ten­sion sim­i­lar elec­tron beam­lines, we en­deavor to gen­er­ate a thor­ough beam­line-rel­e­vant ma­te­r­ial and com­po­nent prop­er­ties down to the range of a liq­uid ni­tro­gen tem­per­a­tures (77 K) and the nom­i­nal op­er­at­ing tem­per­a­ture of a mod­est Gif­ford-McMa­hon cry­ocooler (45 K).
