Temporal δ Compton Camera

Application

Temporal δ Compton Camera can be used for many applications, such as: 
  • Nuclear medicine
  • Nuclear waste management and characterization
  • Decommissioning of a nuclear facilities
  • Gamma imagining
  • Safety and security 

Features

Temporal δ Compton is composed of a portable unit including a processing unit and one detector unit.
  • Temporal imaging read-out electronics.
  • 1 calibrated detector module composed of two 32x32 mm CeBr3 crystals read-out through Phillips DPC3200 Tile Sensor.
  • Embedded software to reconstruct characteristic vector (X,Y,Z,T,E) in real time for each valid scintillation event.
  • Image reconstruction from acquired vectors is done at distance on a laptop.
  • Energy Range 100 keV—3 MeV (Spectroscopy) and 400keV-3MeV (imagery).
  • The sensitivity of the system is better than 1 nSv/h in a 60 s acquisition with a Na-22 source.
  • Available in two versions:
    • Temporal δ V2 - based on CeBr3 
    • Temporal δ V3 - based on CZT with outstanding energy resolution 

DESCRIPTION

Temporal δ is the first device to use this new concept. We are now proposing a portable version with one CeBr3 head, gamma ray and visible imaging and active temperature control. This version is dedicated to energies 300KeV - 2 MeV. This camera has the best angular resolution (6°) and timing resolution (300ps) on the market. It is also extremely sensitive allowing to image natural radioelements (4 kBq at 1 meter ̴ 4 hours) and good imaging of extended sources.
