Title: Fast Bunch-to-Bunch Current Sampling in the Cornell Electron-Positron Collider
Abstract: Preliminary studies of a high resolution Cornell Electron-positron Storage Ring (CESR) bunch-to-bunch signal processing system are described. In these studies, a prototype inductive-integrating, sampling current monitor is evaluated for improved estimation of bunch lifetimes over a series of planned CESR luminosity upgrades. Initial test data indicate significant performance advantages over conventional electrostatic pickup systems in the areas of linearity, dynamic range and beam position sensitivity. Novel features of the fast bunch current monitor include its wideband passive integrating pickup, diplex filter section and high resolution bunch signal processor (BSP). Evaluation studies in CESR indicate this fast bunch monitor is potentially useful in colliders and other storage rings utilizing bunch-to-bunch or bunch train separations down to 80 nanoseconds. Proposed system revisions to permit fast, high resolution bunch train current measurements in future CESR operations are discussed. Commercial availability of several principal bunch-to-bunch current monitor components is noted. >
