                  Single-electron and single-photon sensitivity with a silicon Skipper CCD

                  Single-electron and single-photon sensitivity with a silicon Skipper CCD We have developed a non-destructive readout system that uses a floating-gate amplifier on a thick, fully depleted charge coupled device (CCD) to achieve ultra-low readout noise of 0.068 e- rms/pix. This is the first time th...
