FIG. 1.

Sketch of a VLPC detector. The incident photon is absorbed in the intrinsic (1.12 eV band gap) or in the gain region (0.05 eV band gap), creating an electron-hole pair.

FIG. 3.

Charge distribution from a VLPC pixel operated at 6.8 V at a small counting rate . The open histogram corresponds to data ( entries) and the curve corresponds to a fit using a Poisson distribution convoluted with a Gaussian.

Image of FIG. 4.
FIG. 4.

Charge distribution from the same VLPC pixel shown in Fig. 3, operated at the same bias voltage, but at a counting rate of 4 MHz. The open histogram corresponds to the data ( entries) and the curve corresponds to a fit using a Poisson distribution convoluted with a Gaussian. The mean pedestal was adjusted to match the value of Fig. 3 for the sake of comparison.

Image of FIG. 5.
FIG. 5.

Gain dispersion as function of background rate. Data points are the mean values of 64 VLPCs, taken at a temperature of 9 K and . Simulation points were obtained using 90 000 cells in one pixel, and .

Image of FIG. 6.
FIG. 6.

Sketch of the VLPC model used in the simulation. The area of the pixel is . Up to 90 000 nonoverlapping avalanches (one per isolated cell) can develop in each pixel.
