Conceptual Design of a High Sensitive Versatile Schottky Sensor for the Collector Ring at FAIR.
In: Proceedings IPAC11, [Conference or Workshop Item]

Abstract

The FAIR (Facility for Antiproton and Ion Research) accelerator complex includes the Collector Ring CR, i.e. a dedicated storage ring for secondary particles, rare isotopes and antiprotons. The CR features three different modes of operation: pre-cooling of antiprotons at 3 GeV, pre-cooling of rare isotope beams at 740MeV/u and an isochronous mode for mass measurements. For beam optimizations in all three modes a sensitive Schottky setup is required to monitor very low beam intensities down to single particles. In this paper the conceptual design of a longitudinal Schottky sensor based on a pillbox cavity with adjustable coupling and frequency tuning is presented. The basic measurement principles are depicted and a possible realization is discussed with emphasis on the special requirements of the CR operational modes. Full-wave simulations of the proposed sensor cavity allow for further optimizations.
