Radiation Detectors

The group’s research focus is on the characterisation and development of wide band gap semiconductor and scintillator materials that are suitable for operation as radiation detectors at room temperature or above. 

Materials for n/gamma discrimination

  • Direct detection – semiconducting polymers
  • Indirect detection with novel pulse shape discriminating plastic scintillators
