LOW-LATENCY HIGH-RESOLUTION SINGLE-SHOT BEAM POSITION MONITORS

In this paper design aspects of fast high-resolutio n, single-shot transverse beam position monitors (BPMs) are discussed. The focus is on BPMs which can provide (sub-) micrometer position resolution within measur ement speeds of less than one hundred nanoseconds. Differ ent pickups and analog signal conditioning electronics are reviewed. Their characteristics and limitations wit h respect to application in high-resolution, fast BPM s are pointed out. Exemplary implementations of pickups and electronics are reviewed. A BPM based on a resonant stripline pickup, developed for a fast transverse f eedback system for the European X-FEL, is also presented.
