The WFPC2 CCDs are thick, front-side illuminated devices, with a format of 800x800, 15x15 ? m multi-pinned phase (MPP). MPP allows CCD exposure with the total inversion of all phases. The Si-SiO 2 interface, at the surface of the CCD, is pinned at the substrate potential, directing signal charge away from the Si-SiO 2 interface states towards the buried n-channel. Figure 4.1 shows a schematic which illustrates the principle of MPP (modified from Janesick et al. ... 800 800 . ...

... Charge Coupled Devices (CCD) are currently by far the most widely used type of detector in astronomy. ... After a brief introduction to the VLT Control System, the VLT CCD Detectors Control Software is presented. The VLT Control System is a distributed system consisting of a set of UNIX Workstations, dedicated to high level operations, such as coordination of sub-system activities and interface to the users, and VME-based Local Control Units (LCU), dedicated to the control of sub-systems hardware. ...
