AB  - The European Spallation Source (ESS) is a neutron facility under construction in Lund, Sweden, and established as a 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 pulselength 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 untilthe 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 AMCand RTM modules with custom FPGA firmware implementation and a custom Front-End electronics. In this work, the system architecture, implementation, and test results are presented and discussed.
