Detector characteristics- New detectors
o
Volume effects: Size of sensitive volume :
Small/increase density
o
Energy dependence: Interactions in the detector material
As equivalent as possible to water
o Cable/stem leakage, polarity effect
No polarisation/high response-low contribution from stem-cable
o Dose rate dependence: Recombination, bias voltage
o Temperature dependence
In diodes try to increase gap and traps near conduction band
o Long term stability/irradiation effects
Stable material/lattice with irradiation
