PS2 Beam Transfer Systems: Conceptual Design Considerations

The replacement of CERN's existing 26 GeV Proton Synchrotron (PS) machine with a separated function synchrotron PS2 has been identified as an important part of the future upgrade of the CERN accelerator complex [1,2]. The PS2 will require the design of a number of beam transfer systems associated with injection, extraction, beam dumping and transfer. The different requirements are briefly presented. A first iteration of the conceptual design aspects of these systems is presented, based on the initial PS2 parameter set [3] and assuming a simple 90-degree phase advance FODO lattice. The required equipment sub-system performance is derived and discussed, and possible limitations are analysed. The impact on the overall design and parameter set is discussed, together with some recommendations for the direction of the continuing studies.
