Energy Matching Between LEIR and PS

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. The method was developed in response to the technical and manpower difficulties that altering the LEIR cycle would otherwise have entailed and is only possible because the liaison frequency to which the two machines both synchronize can be considered a free parameter.
