/**
 * \brief Class for a 2 in x 2 in CeBr3 scintillation detector with PMT and connectors
 *
 * This class implements a simplified standard configuration of 2 in x 2 in scintillation
 * detectors as manufactured by the company SCIONIX \cite SCIONIX2020.
 * The sensitive crystals are made of the low-background (as compared to lanthanum-based
 * scintillators) cerium-bromide (CeBr3) material.
 * If not indicated otherwise, dimensions were read off from the technical drawings on the SCIONIX
 *  webpage for scintillation crystals with a photomultiplier tube (PMT) and a preamplifier.
 *
 * In the present implementation, the case of the detector is divided into three parts:
 *
 * - The front part, which contains the entrance window for radiation and encompasses most of the
 * scintillator crystal.
 * - The PMT part, which contains the crystal-PMT interface and the PMT itself.
 * It is mounted inside a PMT case which acts as a magnetic shield.
 * - The connector part, which contains the connector.
 *
 * The geometry is simplified in the sense that the front part of the detector, should resemble
 * the real detector closely, while the back part consists of empty cases.
 * On the outside of the PMT case, two connectors for high voltage supply and signal readout are
 * attached, which are implemented in a simplified way as well.
