Next: Particle Background Rejection Up: Detection Efficiency Previous: Front Illumination . ... The method requires that the CCD substrate be etched from the rear towards the depletion layer boundary. The device can be illuminated through this rear surface, which has a much thinner dead layer than the electrode side. ... The corresponding detection efficiency data are presented in Figure 7, and compared with the predicted data for a 20 m thick depletion layer. ...

... The Radar Decoder correlates the received signal with the code used at transmission, generating the equivalent pulse-radar signal (digital). This process greatly reduces the output data rate over directly sampling with the Radar Interface , but requires that the ephemeris be very well known, so that the bins don't smear into one another. ... The Radar Interface samples an input input signal voltage (in quadrature), and provides it as a digital output to a VME bus for processing or recording. ...

... For historical reasons, it is useful to offer comparisons between the current WFPC2, and its predecessor WF/PC-1, which was returned to Earth in December 1993. Field format: WF/PC-1 contained 8 cameras and CCDs, each CCD having 800 x 800 pixels. ... Many differences derive from the fact that the WF/PC-1 CCDs were thinned, backside illuminated devices whereas the WFPC2 CCDs are thick, frontside illuminated devices. WF/PC-1 CCDs were thinned and backside illuminated. ...
