Large-volume HPGe detectors for rare events with a low deposited energy

The manufacturing technique and the main characteristics of large-volume HPGe detectors with a capacitance of ∼0.5 pF are described. Based on the developed technique, it is possible to produce a detector such that it is comparable in mass to a coaxial HPGe detector, but its energy resolution and detection threshold are close to the values characteristic of small X-ray HPGe detectors.
