Irradiation of a Silicon Strip Detector
up to 10^15 mips/cm^2

Beam

Fluence

The total fluence was 5 * 10^14 protons/cm^2, equivalent to a nonionizing energy loss (NEL) of 10^15 mips/cm^5. The detector response was measured after different fluences using a Ruthenium source. After 2.5 * 10^12, 1.0 * 10^13, 5.0 * 10^13 and 5.0 * 10^14 protons/cm^2 the detector response was measured with a Ruthenium telescope.

Detector

Hamamatsu double sided strip detector. Thickness: 300 µm, pitch: 50 µ

FEE, Readout

The detector is readout using the LBIC amplifier-comparator chip and the CDP64 pipeline. The CDP64 is readout by the VME based DRS.
