MIT/Lincoln Labs CCID20 W40C2 CCD Test Results

Here is a plot of the serial CTE for the second frontside device tested, W40C2. This is a plot of Fe-55 xrays. If the CTE were perfect there would be a straight line across the plot.

Here is a surface plot for the W40C2 CCD while it was cold (about -130°C) and in the lab dewar. The saw-tooth appearance at the back end is an artifact of the analysis. The CCD is actually smooth. Peak-to-peak variation is about 20 microns.

Here is a surface plot for the W40C2 CCD while it was at room temperature and in the lab dewar. There is little difference between this plot and the one obtained with the device cooled. Peak-to-peak variation is about 20 microns.
