R2E-related MD: slow controlled losses for RadMon/BLM cross-checks

The purpose of the dedicated R2E MD has been to evaluate the R factor (i.e. the ratio between the thermal neutron fluence and the high energy hadron fluence (>20MeV) for various tunnel locations, to measure the HEH radiation level gradient along the MBC dipole and on the MQ, to check the ratio the BLM measured dose and RadMon SEU counts and to study the dose gradient between the standard BLM beam axis location and at the level of the equipment location. Within the R2E Mitigation Project, these accurate measurement and cross-check of the mentioned parameters are of great importance for the evaluation and interpretation of the R2E-related radiation levels, as well as for the evaluation of the failure cross-section of specific equipment (i.e. QPS ISO150). In addition, a short part of the MD has been devoted to the comparison of BLM signals generated by loss directed inwards and outwards with respect to the LHC ring.
