Planed diagnostics for the facility for rare isotope beams at Michigan state university

The Facility for Rare Isotope Beams (FRIB) at Michigan State University will utilize a high power, heavy-ion linear accelerator to produce rare isotopes in support of a rich program of fundamental research. The linac will consist of a room temperature-based front-end system producing beams of approximately 0.3MeV per nucleon. Three additional superconducting linac segments will produce beams of >200 MeV/u with a beam power of up to 400 kW. Because of the heavy-ion beam intensities, the required diagnostics will be largely based on non-interceptive approaches. The diagnostics suites that will support commissioning and operation are divided into lower energy <0.3 MeV/u front-end, and higher energy <200 MeV/u driver linac systems. The instruments in the driver linac include strip-line beam position and phase monitors (BPM), toroid beam current monitors (BCM), and 3-D electron scanners to measure rms beam size and emittance to match different linac segments.
