FAQ for Passivated Implanted Planar Silicon (PIPS^®) Detectors

We stock most standard PIPS detectors, so we can deliver within 1-2 weeks. For specific detectors, please contact our Sales Department.

The minimum thickness is 200µm, but we have a limited stock of 100 and 150µm for some detector areas.

No, but our product gamma of SiLi detectors has thicknesses from 1mm to 10mm thicknesses. There is also a possibility to combine two PIPS detectors of 700 or 1000µm.

See this Application Note: "Select the best charged particle detector for your application"

We can supply PIPS detectors with integrated PA or PAA from 450mm² to 1700mm². The reference model is CAMXXXPAA (XXX is the active area surface in mm²)

Thickness 300µm: 40-60V; 500µm: 90-150V; 1000µ: 250-400 V

Yes, it is possible, but this will increase to the noise

Longer lengths are possible but the capacitance of the detector will increase. A Longer cable length can also cause pick-up and/or ringing effects.

It depends on the electronics used. For the 2003BT the max. count rate is 2E6 MeV/sec (1 µA) for electrons and protons. For higher counts saturation will occur and another amplifier is needed, or you need to measure in current mode.

The operating temperature for a standard PIPS is -30°C/+50°C, storage temperature is -100°C/+100°C. For higher or lower temperatures we have BK and CY Options available with storage temperatures of -200°C/+200°C.

A vacuum of 10E-6 mbar is guaranteed for standard assemblies. For 1 specific application it was already used at 10E-10. For detectors mounted on a carrier a ceramic board is preferred.

Yes, we can assemble an acid resistant rubber for CAM PIPS or use TCAM-PIPS

Yes, PIPS are perfect photo diodes and could perfectly be used as photodiode for Cherenkov radiation.

Ensure there is no light, use short cables (<10cm), ensure the pre-amplifier is properly grounded

Typical values of radiation damage are listed in the table below:

The symptoms of radiation damage are: higher leakage current/noise followed by peak broadening and, sometimes, double peaking. In order to prolong the usable "life" of a detector in a radiation field causing damage, the detector must be kept cold (any cooling below room temperature helps; ideally the detector should be cooled to –60°C).
