Abstract / Description:The company PNSensor and the MPI Semiconductor Laboratory are developing and have produced first prototypes of pnCCDs with an avalanche readout which aim at single photon sensitivity in the visible wavelength range. This resolution is provided by an avalanche diode integrated in the readout chain of every CCD column. The diode features a new topology and can collect signal electrons from the CCDs' depleted buried channel. The pixel-structure has been derived from pnCCDs and was optimized for lowest leakage current and for compatibility with the avalanche structures. All advantages of the pnCCDs are maintained, including high quantum efficiency (between 80% and 100%), high frame rate (up to 1000 frames/s) and low leakage current. Possible applications are in the field of High Time Resolution Astrophysics (HTRA). There, fast imaging of faint objects in the visible, such as, e.g. close binary stars or fast rotating neutron stars, requires single photon sensitivity and high frame rates. We present results from proof-of-principle tests carried out on first laboratory prototypes of such devices.
