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. ...

The theory predicts that the oscillation period should be proportional to the square root of the oscillating mass, including the mass of the clip. Note that gravity plays no part here: the oscillation period would be the same on the Moon or in zero-g. Denoting square root by SQRT, we have . ...
