Detectors: two liquid-nitrogen-cooled HPGe
Low-background lead shielding/collimators
Extensive safety devices
Several operating modes available according to required activities
The VEBOS system is designed to perform a complete scan of individuals standing in front of a vertically moving detection equipment.
The measuring equipment is composed of 2 electro-cooled HPGe detectors, or NaI(Tl) scintillators, managed by a multi-channel analyser.
The detectors are shielded with lead collimators in order to reduce the contribution due to environmental background. The collimators can also be used to define a detection field of view, according to the measurement requirements (e.g. full body scan, hot spot deep analysis,etc.).
The detectors and related components are lodged on a mechanically moving shelf, activated by the system software according to the pre-set measurement sequence.
The mechanical structure of VEBOS includes a main frame which acts both as supporting structure as well as shielding from external background contribution.
The primary user interface is provided by a built-in panel PC with proprietary software allowing the complete management of the system, i.e. activation and control of the measurements, display/archive of the results, etc.
Several safety devices are implemented in VEBOS: a base platform that detects an individual presence, interlocks at the maintenance door, and buttons on the holding handles to enable the movement of the detectors.
