DESCRIPTION:Speakers: Shanyn Hart (iThemba LABS)\nThis work investigates t
 he development of a two-stage Compton camera for environmental radiation m
 onitoring\, with a focus on energy resolution\, detection efficiency\, fas
 t timing\, and optimal geometrical configuration. While significant advanc
 es have been made in radiation imaging technologies\, challenges remain in
  achieving high sensitivity and accurate source localisation in complex en
 vironments.\n\nA prototype Compton camera is studied using compact\, low-v
 oltage 14 × 14 × 25.4 mm LaBr$_3$:Ce scintillation detectors coupled to 
 SiPM readout\, with the aim of leveraging the advantages of modern SiPM te
 chnology. These detectors\, manufactured by CapeScint (MA\, USA)\, demonst
 rate excellent energy resolution (3.4% at 662 keV) and fast timing perform
 ance. Scatter event tracking is modelled using the TOPAS Monte Carlo toolk
 it to determine optimal detector geometry and timing characteristics\, com
 plemented by experimental measurements with standard gamma-ray sources.\n\
 nIn addition\, two Cs$_2$LiYCl$_6$ (CLYC-6) SiPM-readout detectors of the 
 same geometry have been commissioned to exploit their neutron sensitivity.
  Pulse shape discrimination is used to distinguish neutron and gamma-ray i
 nteractions\, enabling simultaneous gamma–neutron detection for comprehe
 nsive environmental radiation assessment.\n\nThe development of this syste
 m has the potential to improve radiation source localisation\, contaminati
 on mapping\, and situational awareness in environmental and nuclear safety
  applications. Its compact design and fast-timing capabilities make it wel
 l suited for field deployment in scenarios such as nuclear facility monito
 ring\, waste management\, and emergency response. Preliminary results from
  simulation and experimental studies will be presented.\n\nhttps://indico.
