PSGR is a high precision spectrum gamma tool. It uses a novel and prominent detector which is independently developed.

Using this detector can distinguish the incident position of gamma ray and compensate energy losses in the transmission. This feature makes the vertical resolution of the tool is not affected by the crystal length restrictions. Furthermore, the energy resolution of gamma ray has been greatly improved.
