Subject: status of COT


Tonight I ran tests on the COT in preparation for the baggy tomorrow.
Crate #4 now works after getting a new TRACER (the old TRACER from the
clean room was returned as requested by the XFT'ers).

>From Bob's day shift list yesterday:

   SL8-387 (D,619,18-06-3): 00 dead, 01 hot!, 03 warm, 00 null

      --> Now looks perfect after f-cage work.

   SL8-437 (D,704,19-07-0): 00 dead, 01 hot!, 07 warm, 01 null

      --> Still slightly noisy, could use more copper tape.

   SL8-401 (D,666,18-04-2): 00 dead, 01 hot!, 04 warm, 01 null

      --> Still moderate noise.

   SL7-378 (D,693,09-06-1): 00 dead, 01 hot!, 04 warm
   SL7-379 (D,693,09-06-1): 00 dead, 00 hot!, 09 warm

      --> Still very noisy.

All plug-ins now look OK except for a patch of cells in SL4:

   SL4-252 (D,672,19-17-0): 04 dead, 04 hot!, 00 warm, 00 null
   SL4-254 (D,673,19-17-1): 05 dead, 00 hot!, 00 warm, 00 null
   SL4-256 (D,674,19-17-2): 08 dead, 00 hot!, 00 warm, 00 null

      --> 254 and 256 look like bad rptr or TDC plug-ins, but 252 is
          strange in that the high even-cell wires are dead, which is not
          indicative of a cable dislodged anywhere (see web site
          http://penn01.fnal.gov/~cot/oct2001/ for picture).

I haven't looked at them yet, but both TDC and rptr should be easy to
check out.
