The SPI Veto System

The SPI Veto System


Date: 07 June 2000
Satellite: INTEGRAL
Depicts: Bottom section of veto system

To reduce the background radiation, the detectors on SPI are shielded by bismuth germanate oxide crystals. These act as a veto (anticoincidence) system and extend around the bottom and side of the detector almost completely up to the coded mask. This image shows the bottom section of the system, that resides below the detector (see related images).
