Abstract:

I have calculated the constants for the DCU voltage measurements. An initial study of the DCU rtd and internal temperature sensors is underway. Cold finger effects are studied from 2008 to the present. Check all 2011 DCU data for drifts from 2010 values due to radiation damage. No statistically significant drifts are seen.
