Abstract

In the paper, the physical model of a doped scintilator is described. The Monte Carlo type code NEU-7 [Cvachovec, Cvachovec, and Tajovsky, Nucl. Math. Inst. Phys. Res. A, Vol. 476, 2002, pp. 200–202], which was created for a NE-213 and stilben type scintillators containing also hydrogen and carbon only, was extended for scintillators containing 10B, 11B, and O also.

The modified NEU-7 code is called NEUB-7, and with it the response function for scintilator BC-523A doped with 4.41 % 10B was calculated. The dimensions of the cylindrical scintilator are 5 × 6 in.², corresponding to the real detector. The created response matrix was implemented in the unfolding code with the maximum likelihood method.
