Abstract: 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 (pseudorapidity range 2.0–3.0). Changing the method of light collection from the most irradiated scintillator tiles will provide a long-term usage of scintillator 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 with electrons (E ≈ 4 MeV) are discussed.
