Crab Cavity Development
The HL-LHC upgrade will use deflecting (or crab) cavities to compensate for geometric luminosity loss at low * and non-zero crossing angle. A local scheme with crab cavity pairs across the IPs is used employing compact crab cavities at 400 MHz. Design of the cavities, the cryomodules and the RF system is well advanced. The LHC crab cavities will be validated initially with proton beam in the ...

متن کاملStatus of the Ilc Crab Cavity Development
The International Linear Collider (ILC) will require two dipole cavities to “crab" the electron and positron bunches prior to their collision. It is proposed to use two 9 cell SCRF dipole cavities operating at a frequency of 3.9 GHz, with a transverse gradient of 3.8MV/m in order to provide the required transverse kick. Extensive numerical modelling of this cavity and its couplers has been perf...
متن کاملStudy of crab cavity option for LHC
It is prefered to make a larger crossing angle to avoid parasitic collisions between beams in LHC. The transverselongitudinal aspect ratio of the LHC beam is 17 μm/7.5 cm=0.23 × 10−3. Crossing angle larger than the aspect ratio causes geometrical degradation of luminosity. Crab cavity can realizes head-on collision without crossing angle effectively, with the result that it recovers these lumin...
متن کاملDesign of the ILC Crab Cavity System
The International Linear Collider (ILC) has a 14 mrad crossing angle in order to aid extraction of spent bunches. As a result of the bunch shape at the interaction point, this crossing angle at the collision causes a large luminosity loss which can be recovered by rotating the bunches prior to collision using a crab cavity. The ILC baseline crab cavity is a 9-cell superconducting dipole cavity ...
