	The European Spallation Source, currently under construction in Lund, Sweden, will be a neutron source based on partly superconducting linac, accelerating protons to 2GeV with a peak current of 62.5mA, ultimately delivering a 5MW beam to a rotating tungsten target. For a successful tuning and operation of a linac, a Beam Loss Monitoring (BLM) system is required. The system is designed to protect the machine from beam-induced damage and unnecessary activation of the components. This contribution focuses on one of the BLM systems to be deployed at the ESS linac, namely the neutron sensitive BLM (nBLM). Recently, test of the nBLM data acquisition chain including the detector has been performed at LINAC4, at CERN. The test represents first evaluation of the system prototype in realistic environment. Results of the test will be presented together with an overview of the ESS nBLM system.

	The European Spallation Source (ESS) is a neutron facility under construction in Lund, Sweden, and established as an European collaboration between different member countries. The machine is a 2 GeV proton LINAC with a nominal beam current of 62.5 mA, 2.86 ms of pulse length and a bunch repetition rate of 352 MHz. The Beam Position and Phase Monitors (BPM) at ESS were designed to satisfy the specifications for the different beam modes, which span from 5 µs pulse length and 6.3 mA beam until the nominal beam condition. The system is designed for standard beam position measurements for beam trajectory correction and for beam phase measurements for cavity phase tuning, imposing restrictions on the sensor design and electronics architecture. Approximately a hundred BPM’s were manufactured and are being installed by partners in collaboration with ESS. The BPM system comprises a MicroTCA.4 electronics based in COTS AMC and RTM modules with custom FPGA firmware implementation and a custom Front-End electronics. In this work, the system architecture, implementation, performance, and test results are presented and discussed.

The European Spallation Source (ESS) is a neutron facility under construction in Lund, Sweden, and established as an European collaboration between different member countries. The machine is a 2 GeV proton LINAC with a nominal beam current of 62.5 mA, 2.86 ms of pulse length and a bunch repetition rate of 352 MHz. The Beam Position and Phase Monitors (BPM) at ESS were designed to satisfy the specifications for the different beam modes, which span from 5 µs pulse length and 6.3 mA beam until the nominal beam condition. The system is designed for standard beam position measurements for beam trajectory correction and for beam phase measurements for cavity phase tuning, imposing restrictions on the sensor design and electronics architecture. Approximately a hundred BPM’s were manufactured and are being installed by partners in collaboration with ESS. The BPM system comprises a MicroTCA.4 electronics based in COTS AMC and RTM modules with custom FPGA firmware implementation and a custom Front-End electronics. In this work, the system architecture, implementation, performance, and test results are presented and discussed.
