Title: TRIFIC: The TRIUMF Fast Ion Counter

Abstract

The TRIUMF Fast Ion Counter (TRIFIC) is a tilted-grid gas counter detector for identifying the impurities in radioactive ion beams (RIBs). Placed at zero degrees downstream of a primary reaction target at the TRIUMF ISAC-II facility, TRIFIC provides accurate Z identification of beam species on an event-by-event basis at a rate of up to 5 × 10 5 particles per second and functions as a beam composition monitor at rates up to 5 × 10 7 particles per second. With this additional level of diagnostics, RIB experiments at TRIUMF are able to reach levels of sensitivity not previously possible. Details pertaining to the construction and instrumentation of TRIFIC as well as results from the commissioning of the detector are introduced.
