Marco Garattini (CERN)
Beam steering performance of bent silicon crystals irradiated with high-intensity and high-energy protons have been studied. In particular, crystals of the type used for collimation purposes at the CERN Large Hadron Collider have been irradiated at the HiRadMat CERN facility with 2.5 x 10^13 440 GeV protons, with a pulse length of 7.2 μs, to study possible changes in bending angle and...

HiRadMat is an unique facility to experimentally verify the consequences of beam impact on accelerator equipment. These experiments are essential for machine protection to validate simulation results and confirm the consequences of beam failure cases in the LHC and future accelerators. In the early years of HiRadMat, a dedicated experiment could prove the existence of the so-called...

J-PARC, Japan Proton Accelerator Research Complex, consists of a series of the world’s most intense accelerators and experimental facilities producing and utilizing high-intensity proton beams. Future experiments at HiRadMat facility will provide great opportunities to J-PARC for undergoing research and developments. In this talk following three LoIs submitted from J-PARC are overviewed:...

Proton impact tests in the HiRadMat facilitiy, performed during the LHC Run 1 and Run 2, were of key importance for the Collimation project. They followed up similar tests on collimator elements done in 2004 and 2006 in the TT40 area, and provided outstanding inputs on the choice of collimator materials, as well as on the validation of the design proposed for critical sub-assemblies (e.g. the...

The HiRadMat facility offers a unique possibility to study the effect of possible HL-LHC beam failure scenarios on the ATLAS detector. The requirement of detector safety is of primary importance for an accelerator, specially at HL-LHC where the increase of the TAS aperture will potentially increase the exposure of detectors to machine induced background.
By mean of complex Monte Carlo...

Continuation of study of the signal linearity and response, calibration, saturation, comparison of different types of BLM detectors. The LHC type of Ionization Chambers, IC08 and IC17, were tested in 2017-2018 and will need to continue to be tested in 2020-2022 to check the aging of IC and comparison with Run 2 data. This is highly important for evaluating the requirement of beyond 20 years of...

Prof. Piotr Cupial (AGH University of Science and Technology)
The ESS$\nu$SB project, financed by the EU H2020 programme as a 4-year design study (Grant Agreement No 777419), proposes to use the protons produced by the LINAC of the European Spallation Sources (ESS), currently under construction at Lund (Sweden), to deliver a neutrino superbeam. A very challenging component of this project is the enormous target heat load generated by a 5 MW proton beam....
