oPAC Fellow participating in Compact Energy Recovery Linac commissioning
oPAC Fellow Alessandra Valloni is currently at KEK (High Energy Accelerator Research Organization, Tsukuba, Ibaraki Prefecture, Japan) participating in the Compact Energy Recovery Linac commissioning.
On Thursday 12th June Alessandra will give the seminar "Accelerator Development for LHeC and LTF" and she has already shared the abstract with the oPAC community:
The Large Hadron Electron Collider (LHeC) is a proposed facility for deep-inelastic electron-proton/nucleus scattering, realized by colliding one of the two LHC proton (or heavy-ion) beams with 60 GeV electrons provided by a new accelerator. Following the release of its conceptual design report in 2012, the configuration of an energy recovery linac with racetrack shape has been chosen as the LHeC baseline.
Motivated by the discovery of the Higgs boson at the LHC, further LHeC design work during the last two years has adapted the electron and high luminosity optics and beam parameters in order to achieve a luminosity around 1034 cm-2s-1, which is desirable for precision Higgs physics studies at the LHeC.
In parallel the design of an LHeC Test Facility (LTF) has been advanced. Aside from various other technical and physics goals, this test facility will, in particular, aim at investigating the ERL principle in an LHeC-like configuration, including electron injector and return-arc magnets, at providing a test stand for superconducting SRF cavity modules, as well as at performing some LHeC-related detector R&D. One possible user application of the LTF beam is for generating controlled beam induced quenches of SC magnets. A planned staged construction of the LTF, including a number of well-defined intermediate steps, will lead to an ultimate beam energy of about 1 GeV.
This talk will present an overview of the LHeC & LTF design, some recent activities and an outlook on further developments.
