MIT/Lincoln Labs CCID20 W105C2 CCD Test Results

This is a high-resistivity phase 2 MIT/Lincoln Labs 2Kx4K CCD. It has improved brick wall. This device has suffered a breakdown during the initial cool-down. The B amplifier stopped working when the temperature got to -127C and hasn't worked since. A summary report is available. Noteworthy points about this CCD include:

Before it broke down it had generally very nice characteristics.

Original postscript files are available from our anonymous ftp server and these provide better resolution and clarity than is usually possible on a web page. Here are a few figures to illustrate device highlights:

Surface flatness

This CCD has a fairly large curvature.

There is a bow of about 20 µm in this CCD. This is the most we've seen in any phase 2 device, but may still be entirely acceptable in many applications.
