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
