Title Crab Cavity and Cryomodule Development for HL-LHC
Abstract The HL-LHC pro­ject aims at in­creas­ing the LHC lu­mi­nos­ity by a fac­tor 10 be­yond the de­sign value. The in­stal­la­tion of a set of RF Crab Cav­i­ties to in­crease bunch cross­ing angle is one of the key up­grades of the pro­gram. Two con­cepts, Dou­ble Quar­ter Wave (DQW) and RF Di­pole (RFD) have been pro­posed and are being pro­duced in par­al­lel for test in the SPS beam be­fore the next long shut­down of CERN ac­cel­er­a­tor’s com­plex. In the re­tained con­cept, two cav­i­ties are hosted in one sin­gle cry­omod­ule, pro­vid­ing ther­mal in­su­la­tion and in­ter­fac­ing with RF cou­pling, tun­ing, cryo­gen­ics and beam vac­uum. This paper overviews the main de­sign choices for the cry­omod­ule and its dif­fer­ent com­po­nents, which have the goal of op­ti­miz­ing the struc­tural, ther­mal and elec­tro-mag­netic be­hav­ior of the sys­tem, while re­spect­ing the ex­ist­ing con­straints in terms of in­te­gra­tion in the ac­cel­er­a­tor en­vi­ron­ment. Pro­to­typ­ing and test­ing of the most crit­i­cal com­po­nents, man­u­fac­tur­ing, prepa­ra­tion and in­stal­la­tion strate­gies are also de­scribed.
