“…The relationship of dose to "damage" (loss of light output) was assumed to be linear. The assumption of linearity has been checked experimentally [5]. Therefore, the assumed depth (z) distribution of the response of a radiation damaged EM calorimeter can be written; 1-d(z) = I -a E(z) (1) where dis the fractional light loss (damage), E(z) is the energy profile of 10 GeV electrons, and a is a normalization factor.…”

The radiation hardness of a 3HF-tile/02-WLS-fiber calorimeter with two different tile/fiber patterns has been studied. Two calorimeter modules were irradiated up to 10 Mrad with the BEPC 1.3 Ge V electron beam. The radiation damage of these modules is compared with our previous measurements from SCSN81-tile/BCF91 AWLS fiber modules [1,2]. The longitudinal damage profiles are fitted as a function of depth. I. INfRODUCTION From our previous studies on irradiation of 8 scintillator tile/wavelength-shifter (WLS) fiber modules, we concluded that: (I) The scintillator tile/WLS fiber technique can be used in the SDC barrel calorimeter. The existing commercial scintillator (SCSN81) and WLS fiber (BCF91A) are suitable for the SDC barrel calorimeter [!]. (2) The Multi-Fiber Module (MFM) structure increases the radiation hardness of the tile/fiber system [2].
