An improvement of a radiation hardness of the CMS Hadron Endcap Calorimeters under increased LHC luminosity

Mostrar otras versiones (1)

One very important aspect of an upgrade program of the Hadron Endcap Calorimeters (HE) is connected with the need to provide a radiation hardness of individual detectors (tiles), located in the first five layers of each HE for towers 23 - 29 (pseudo rapidity range 2.0 - 3.0). Changing the method of...

description One very important aspect of an upgrade program of the Hadron Endcap Calorimeters (HE) is connected with the need to provide a radiation hardness of individual detectors (tiles), located in the first five layers of each HE for towers 23 - 29 (pseudo rapidity range 2.0 - 3.0). Changing the method of light collection from the most irradiated scintillator tiles will provide a longer term use of scintillators as a detector of HE under increased LHC luminosity. The experimental results of the measurements for the different assemblies (scintillator SCSN-81 and the WLS fiber Y11) irradiated by electrons (E ~ 4 MeV) are discussed.
