| الوصف: | The use of High Purity Germanium detectors operated in ionization mode at cryogenic temperatures is investigated as an external background mitigation solution for bolometers used in rare-event search experiments. A simple experimental setup with very partial coverage, running a 52-g $\mathrm{Li_2WO_4}$ bolometer sandwiched in-between two 2-cm thick High Purity Germanium cylindrical detectors in a dry cryostat, shows promising rejection to environmental gammas and atmospheric muons backgrounds. The acquired data are used together with a Monte Carlo simulation of the setup to extract the main contributions to the external backgrounds expected in an above ground experiment, such as e.g.~current and future experimental efforts targeting the detection of coherent elastic neutrino-nucleus scattering at reactor facilities. Based on all these results, a $\mathrm{4\pi}$ coverage similar veto system achieving a $\mathcal{O}$(10 keV) energy threshold is expected to achieve a $\mathrm{\gtrsim}$ 70 \% and a $\mathrm{\gtrsim}$ 97 \% rejection power for gamma-like and muon-like events, respectively.
