Energy Matching Between LEIR and PS / Hancock, Steven (CERN)
This note gives an operations procedure based on the PS Tomoscope and Trajectory Measurement System (TMS) to adjust the ion beam momentum at transfer from LEIR to the PS in a way that guarantees a correct transfer between the two machines without any modification of the LEIR magnetic cycle. [...]
