Description

The European Spallation Source (ESS) in Lund, Sweden, is a pulsed neutron source based on a proton linac. During beam commissioning in 2025, the 870 MeV protons of 6 mA current, 5 microsecond pulse length and 1 Hz repetition delivered to tuning beam dump.  
Beam Loss Monitoring (BLM) system is to protect the accelerator from beam-induced damage and unnecessary activation of the components.  The one of ESS BLM detector is ionization chamber (icBLM) . All 266 chambers are installed, connected, powered. There was performed a several tests : the leakage current tests at CERN and ESS labs, self-integration, DAQ, HV tests in tunnel of whole chain of system, calibration test at HiRadMat facility at CERN. This contribution focuses on the results from acceptance and calibration campaigns made at end of 2025 and in 2026 by BLM team with help of DEKRA Xray gun for readiness for beam on target commissioning.
