Part II: HPD - Basic<br />
1. Photocathode (Alkali / GaAs)<br />
2. High Electric field (HV 2 to 20 kV)<br />
3. Gain in one step by energy dissipation <strong>of</strong> keV pe’s in solid-state detector; ENF ~1<br />
4. Secondary carriers for multiplication are produced and directly readout by<br />
• Si-Anode+ROC = HPD / ISPA Tube …<br />
• APD = HAPD<br />
• Back thinned CCD = EBCCD<br />
• Back thinned CMOS = EBCMOS<br />
