CERN SC RF and ERL Test Facility Plans | |
|
||
| A proposal for a scientific and technical R&D facility based on a recirculating energy recovery linac (ERL) is under active development at CERN. It promises exciting technology developments of principal importance since the ERL technique is a unique way of economising the power consumption which possibly is the biggest common challenge of the next generation of energy frontier accelerators. Aside from various other technical and physics goals and applications considered, this ERL facility, in particular, aims at investigating the ERL principle, including its specific beam dynamics, operational and reliability issues, and at providing a test stand for SC RF cavity modules. The talk presents the high energy ERL configuration, and it outlines the concept and purpose of a 1 GeV electron beam 3-pass ERL facility. | ||

| TUIBLH2026 | LHeC ERL Design and Beam-Dynamics Issues | 15 |
|
||
| The LHeC aims at delivering an electron beam for collision with the LHC proton beam. The current baseline design consists of a multi-pass superconductive energy recovery linac operating in a continuous wave mode. Here, we describe the overall layout of such ERL complex located on the LHC site. We present an optimized multi-pass linac optics enabling operation of the proposed 3-pass RLA in the Energy Recovery mode. We also describe emittance preserving return arc optics architecture; including layout and optics of the arc switch-yard. High current (>100 mA) beam operation in the linacs excites long range wake-fields between bunches of different turns, which induce instabilities and might cause beam losses. The impact of long-range wake-fields, synchrotron radiation, and beam-beam effects has been assessed in this paper. | ||
