Several scientific users from different communities, such as nuclear medicine, ionizing radiation metrology, nuclear energy industries, and fundamental physics are seeking for a precise knowledge of beta spectra. Consequently, it is of great interest to investigate the spectral shape of beta decaying nuclei with best possible precision. In this work, we aim to investigate precisely β~ decays. For this purpose, we have developed a quasi 4π beta spectrometer based on Silicon detectors (PIPS®). The measurement system is characterized by conversion electron peaks of 109Cd and 207Bi and has been compared with Monte Carlo simulations using nuclear decay data. The preliminary measurements of 14C (allowed transition) and 36Cl (second forbidden non-unique transition) decays have been performed and compared with simulations using the PENELOPE Monte Carlo code.
