Pho<strong>to</strong>ndetec<strong>to</strong>r Requirements<br />
Highest possible pho<strong>to</strong>n detection efficiency (PDE)<br />
<strong>with</strong> peak response between 300 nm <strong>and</strong> 600 nm<br />
Lower energy threshold<br />
Better event reconstruction<br />
S<strong>in</strong>gle pe signal widths about 3 ns <strong>to</strong> 8 ns<br />
● wider signals -> contam<strong>in</strong>ation from NSB<br />
● narrower signals -> Cherenkov pho<strong>to</strong>ns do not pile up<br />
Jitter (e.g. TTS) < 1-2ns<br />
M<strong>in</strong>imized non-Poisson tails <strong>in</strong> pulse height distribution<br />
Afterpuls<strong>in</strong>g (PMTs) / Optical Crosstalk (<strong>SiPMs</strong>)<br />
Reduce accidental trigger<br />
