The number after each value refers to the source listed below. Values are as published by the manufacturer; the exact configuration is always confirmed in our quotation.
| Detector type | P-type reverse coaxial HPGe well detector1 |
|---|---|
| Active germanium volume | 90–450 cm³ for models in the configuration guide2 |
| Resolution measurement geometry | Point source in the well, 1 cm from its bottom2 |
|---|
| Energy range | Approximately 10 keV–10 MeV1 |
|---|
| Preamplifier | Optional remote -HJ1 |
|---|
| Sample well diameter | 10 or 15.5 mm depending on model2 |
|---|---|
| Endcap | Aluminium as standard; OFHC copper with high-purity aluminium well tube (0.02 in wall) on low-background -LB-AWT/-XLB-AWT options2 |
