Contract
Paul prepared a version of the statement of work, but the text was lost. Mark volunteered to write a draft.
Time-Walk Correction Tests
Sasha tried out the technique that Elton described in a recent note. See his plots for details. Cosmic data taken with prototype counters show some of the general features expected, but there is a non-Laudau distributed background in the sample that complicates the fits.
