Sector 1 - began training stringers to turn on high voltage and look for signals using STB probe and ADB monitoring system.
Sector 5 - restrung Guard and Field wires for replaced feed throughs in SL1 (Fields: 167-11, 187-2, 223-8 and 225-11. Guards: 227-10 and 228-3). All wires strung were continuity tested for potential crossed wires.
Sector 6 - tested SL2 Field wires from row 134 to 168 (245 wires).
10/02/12
Sector 1 - Injected a 10 MHz square wave with a 40 mV peak-peak amplitude into each channel of the ADB monitor system. Tested the gain on A and B of each channel. Preliminary results show 5 channels that may not be functioning properly.
Sector 5 - removed and replaced 4 more damaged or glue contaminated feed throughs that were found during visual inspection (SL1: 16-2 (Sense). SL2: 37-1 (Guard), 227-8 (Field) and 227-9 (Field)).
Sector 6 - tested SL2 Field wires from row 169 to 189 (147 wires).
Temperatures in the cleanroom have been decreasing slowly over the last week. Increased the temperature set point of the HVAC system by one degree to keep temperatures within cleanroom specifications. Will monitor and report any issues.
10/03/12
Sector 1 - Injected a 1kHz -40mV peak pulse with a 0.1% duty cycle directly into the ADB monitor system to verify ECL output for all 96 channels. All channels confirmed a -1V peak with a 1us pulse width. Mapped Layer/Wire to corresponding ADB channel. The map that was sent to us does not correspond between ADB channel and Layer/Wire.
Sector 6 - tested Field wires from row 190 to 227 (263 wires).
10/04/12
Sector 1 - Spent considerable time trouble shooting ribbon cables to verify that an injected signal maps correctly from each STB channel to each ADB channel and produces an ECL output.
Sector 5 - completed weekly Tension Trend test.
Sector 6 - completed weekly Tension Trend test. Tested SL2 Sense wires from row 3 to 39 (109 wires).
Completed weekly clean in cleanroom.
10/08/12
Sector 1 - reorganized rack to accommodate for the VME crate.
Sector 5 - rotated chamber; repositioned magnet; leveled the stringing arm and aligned the chamber for Sense wire stringing in SL2.
Sector 6 - tested SL2 Sense wires from row 40-146 (321 wires).
