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. ...

A diagram of the output register of the PlutoCCD CCD is shown in Figure 5-1 and illustrates the setup clock waveform and DC potentials for the last three pixels of the serial shift register (V f ), before it is collected in the Summing Well (V sw ), transferred to the Last Gate (V otg ), and then sampled by the output MOSFET, when the charge is dumped to the output node using the amplifier with a Voltage Reference (V ref ), Reset Gate (V rg ), and output drain (V dd ). ...
