  The Advanced Rare Isotope & Electron Linac (ARIEL) facility at TRIUMF consists of an electron linear accelerator (e-linac) capable of currents up to 10 mA at an energy of 30 MeV, giving a total available beam power of 300 kW. In addition, the e-linac can be run in pulsed operation down to beam pulses of 5 μs, up to CW. A Machine Protection System (MPS) is required to protect the accelerator from hazardous beam spills and must turn off the electron gun within 10 μs of detection. The MPS consists of two types of beam loss monitors, a front-end beam loss monitor board developed at TRIUMF, and EPICS-based controls to establish operating modes. A trip time of 10 μs has been demonstrated, along with a 106 dynamic range and sensitivity down to 100 pA. This paper is focused on the current status of the beam loss monitor detection system.
