If the Sector 5 rollers can not be repaired, we may need to explore options for replacement. The soft, wool like material that surrounds the rollers is not uniform and causes an uneven surface once the roller is covered with the balloon.

 Temperatures are still within specifications. At 17:45, the daily 5 minute average for each probe was as follows: (1)70.49&deg;, (2)70.14&deg;, (3)70.12&deg;, (4)70.11&deg;. The humidity daily 5 minute average for the same time was 21.05%.

+Sector 1 - Identified cross-talk occurring on wires/channels near the channel that is having a signal injected. Obtained a new signal cable for HVTB and ADB to try on Monday. Signal cables sent to us use connectors that do not provide strain relief for the knife contacts with the wires in the cable. Had one pull apart, also identified this as a source of poor contact points within the wire that was causing significant amounts of ringing in the ADB-front panel's analog output signals. New cable should take care of this problem. Analyzed output of Ch. 1-14, characterized behavior with existing bad cabling. Also put the "bad" op-amp we identified from Ch. 90 on the HVTB into Ch. 96 and observed ADB and ECL signals with a "good" and "bad" op-amp. Currently the good op-amps in all channels result in two "ragged" pulses per injected pulse in the ADB-front panel's analog signals and variable triggering behavior with the ECL that would result in junk data if hooked up to a TDC. The "ragged" pulses are most likely an artifact of the cabling being used, and should be resolved with the new cabling.
 Sector 5 - strung 45 Sense wires (now on SL2 - row 61). Completed weekly Tension Trend test.
