... WFC3 Data Handbook > Chapter 6: Charge Transfer Efficiency (CTE) > 6.2 The Nature Of CTE Losses . ... The Nature Of CTE Losses . ... These traps can temporarily detain individual electrons. ... The dip between 12 and 30 electrons shows the "sweet spot" background level, where the charge transfer is maximized at low background levels. ... We see that a charge packet that contains just one electron will encounter 20 traps on its 2000-pixel journey to the serial register, if there is no background. ...

Next: CCD Scientific Performance Up: CCD Operation Previous: CCD Operation . A visible light photon releases only one electron-hole pair, and consequently many photons must be collected in each pixel for a measurable signal to be produced. ... This use as an imaging X-ray spectrometer requires that no more than one photon is incident on each pixel in any image frame, which imposes a requirement that image collection times be limited to ~seconds for typical astronomical applications. ...
