Description
The CMS collaboration is planning to upgrade the forward calorimeters as these will not be sufficiently performant with the expected HL-LHC (High Luminosity LHC) conditions. After CMS committee decision, the High Granularity Calorimeter (HGC) is the technology chosen for this upgrade. It is realized as a sampling calorimeter with layers of silicon detectors that feature very high longitudinal and lateral granularities, and a coarser segmentation backing hadronic calorimeter based on scintillators as active material. The sensors are realized as pad detectors of size in the order of 1 cm2 with an active thickness between 100µm and 300µm depending on the position respectively the expected radiation levels. After the first results on neutron irradiation of 300µm, 200µm and 100µm n-on-p and p-on-n devices that have been irradiated to fluences up to 1.5E16 n/cm2 at Ljubljana Nuclear Reactor; We present, the latest results in terms of radiation hardness of these pad detectors.
