Temperature Dependencies<br />
Critical E-field for breakdown depends on temperature<br />
Temperature dependent breakdown voltage<br />
Temperature dependent ga<strong>in</strong> <strong>and</strong> PDE<br />
Intr<strong>in</strong>sic dark rates are high but not an issue for Cherenkov telescopes<br />
NSB rates are generally higher -> no cool<strong>in</strong>g needed<br />
For example <strong>in</strong> the SCT we expect ~40 MHz NSB <strong>in</strong> a 6x6 mm 2 pixel<br />
-> about 1 MHz NSB per mm 2 sensor area<br />
Compare <strong>to</strong> typical <strong>in</strong>tr<strong>in</strong>sic dark rates <strong>of</strong> MPPCs <strong>of</strong> a few 100 kHz per mm 2<br />
