LEIR Closed Orbit Measurement proposal

For the Low Energy Ion Ring (LEIR) continuous (every 10ms) tracking of the closed orbit is necessary during the acceleration and on request. To do so it is foreseen to re-use parts of the existing hardware, mainly the pick-ups (PUs), from LEAR while other parts like the head amplifiers and the acquisition system will have to be re-designed. This note addresses the hardware and software needed for an analogue based acquisition system as well as a DSP based solution. The commissioning of LEIR is foreseen for mid 2005.
