(1) Photonics Science Limited, Robertsbridge, East Sussex, TN32 3LA, United Kingdom.
2 CCD cameras High performance thermoelectrically cooled image intensified CCD cameras
Scintillator AST type ND blue, based upon6Li with added ZnS:AgThickness: 0.45 mmTotal active area: 252 x 198 mm2Each pixel is 144 µm on edgeDistance to sample: 35 mm to 195 mm
Geometry from transmission (γ=0º) to back scattering (γ=180º), preferred γ angles: 0º, 90º, 180ºBeam divergence : about h= 0.6º, v= 0.8º
Coupling between both Via a tapered fibre-optic, bonded directly onto the CCD, to give maximum transmission and high sensitivity
