The strategy for machine protection and quench prevention of the super-conducting elements of the Large Hadron Collider (LHC) at the European Organisation for Nuclear Research (CERN) is heavily reliant on its beam loss monitoring system. This is one of the most complex and large-scale beam instrumentation systems deployed anywhere in the world. In order to augment the system's dependability and verify the correct connection of each of the approximately 4000 detectors distributed around the 27 km LHC ring to its assigned channel in the electronic system, a mobile irradiation instrument has been designed and built. This instrument can be easily and safely transported along the LHC tunnel and imitate a localised beam loss at each BLM detector. This paper describes the concept of the instrument, its engineering design, the safety measures included and recent upgrades. Possible future improvements of the device are also considered.

The European Spallation Source (ESS) to be under construction in Lund, Sweden, will provide a highest average intensity beam from a 5 MW superconducting proton linear accelerator to produce spallation neutrons. A serious problem for high current accelerators is the high density of the beam, which is able to destroy the equipment, to make a quench of super conductive magnets. Loss of even a small fraction of this intense beam would result in high radiation and destruction of the equipment. The Beam Loss Monitor (BLM) system must be sensitive to different level of losses in different accelerator locations. The main ESS beam loss detector type is ionization chamber (icBLM). The detector is originally designed for CERN LHC and 4250 monitors were produced in 2006-2008, now widely used in almost all accelerators at CERN, in IHEP (Protvino, Russia). In 2014-2017 a new production of 830 icBLM was performed to replenish spares for LHC and to make series for ESS, GSI. The requirements, design, testing and layout for ESS accelerator are presented
