SGP/NIMFR/E13 - Head connector failure

The direct beam, head and tube temperatures went to zero beginning 20050105. The head 
connector was reseated 20050118 correcting the problem but the head signal cable was stressed 
again 20050120 through 20050121 resulting in poor data.  Data between 20050118-20050120 
may be ok but should be examined carefully.
