  The Cor­nell-BNL ERL Test Ac­cel­er­a­tor (CBETA) de­vel­oped sev­eral en­ergy-sav­ing mea­sures: multi-turn en­ergy re­cov­ery, low-loss su­per­con­duct­ing ra­diofre­quency (SRF) cav­i­ties, and per­ma­nent mag­nets. With green tech­nol­ogy be­com­ing im­per­a­tive for new high-power ac­cel­er­a­tors, the lessons learned will be im­por­tant for pro­jects like the FCC-ee or new light sources, where spin­offs and lessons learned from CBETA are al­ready con­sid­ered for mod­ern de­signs.

  Co­her­ent Syn­chro­tron Ra­di­a­tion (CSR) in bend­ing mag­nets poses an im­por­tant limit for elec­tron beams to reach high bright­ness in novel ac­cel­er­a­tors. While the lon­gi­tu­di­nal wake­field has been well stud­ied in one-di­men­sional CSR the­ory and im­ple­mented in var­i­ous sim­u­la­tion codes, trans­verse wake­fields have re­ceived less at­ten­tion. Fol­low­ing the re­cently de­vel­oped two-di­men­sional CSR the­ory, we de­vel­oped a Python code sim­u­lat­ing the steady-state two-di­men­sional CSR ef­fects. The com­puted CSR wakes have been bench­marked with the­ory and other sim­u­la­tion codes. To speed up com­pu­ta­tion speed, the code ap­plies vec­tor­iza­tion, par­al­lel pro­cess­ing, and Numba in Python.

  SLAC is de­vel­op­ing the Light­source Uni­fied Mod­el­ing En­vi­ron­ment (LUME) for ef­fi­cient mod­el­ing of X-ray free elec­tron laser (XFEL) per­for­mance. This pro­ject takes a holis­tic ap­proach start­ing with the sim­u­la­tion of the elec­tron beams, to the pro­duc­tion of the pho­ton pulses, to their trans­port through the op­ti­cal com­po­nents of the beam­line, to their in­ter­ac­tion with the sam­ples and the sim­u­la­tion of the de­tec­tors, and fi­nally fol­lowed by the analy­sis of sim­u­lated data. LUME lever­ages ex­ist­ing, well-es­tab­lished sim­u­la­tion codes, and pro­vides stan­dard in­ter­faces to these codes via open-source Python pack­ages. Data are ex­changed in stan­dard for­mats based on openPMD and its ex­ten­sions. The plat­form is built with an open, well-doc­u­mented ar­chi­tec­ture so that sci­ence groups around the world can con­tribute spe­cific ex­per­i­men­tal de­signs and soft­ware mod­ules, ad­vanc­ing both their sci­en­tific in­ter­ests and a broader knowl­edge of the op­por­tu­ni­ties pro­vided by the ex­cep­tional ca­pa­bil­i­ties of X-ray FELs.
