Title Development of Instrumentation for Low Energy Beams
Contributors
Abstract Ion and antiproton beams at keV energies are very attractive for a number of fundamental studies. The diagnostic of these beams, however, is a challenge because most detectors are either not sensitive enough or too disturbing. In this work, a set of optimised detectors has been developed to suit the particular beam diagnostic needs of the novel Ultra-low-energy Storage Ring (USR) at the future Facility for Low-energy Antiproton and Ion Research (FLAIR), accommodating as few as 107 particles at energies down to 20 keV. The instrumentation includes beam profile monitors based on scintillating screens and secondary electron emission, ultra-sensitive Faraday cups for absolute intensity measurements, and capacitive pick-ups for on-line beam position monitoring. This thesis presents results from theoretical studies and modelling, the design of prototypes of all monitors, and results from measurements with beam. All detectors are characterised in detail, their individual limitations are described and options for further improvements are indicated. Whilst initially developed for the USR, the instrumentation described in this thesis is also well suited for use in other low-intensity, low-energy accelerators, storage rings, and beam lines
