Arrived about 10:30 with Aaron from LGR. Sunny, cool, windy.

Took down and removed LGR trailer and tower. Measurement height was 24 feet (7.32m), tubing length was 36.5 feet (11.15m) and the flow rate was about 40 lpm. Pump was a BOC Edwards XDS 35i.

All tower systems were running despite generator maintenance on Saturday.

I adjusted the bypass valve to return the pressure to 143 Torr.

Added foam insulation to the inside of the new box. Box temperature was 82F just after noontime. AC was set to maintain 90 F inside the box, I lowered this to 80 F. I heard AC come on. Serial data from LGR was down for a little while during foam installation.

Interrior dimensions of box: 37-1/2” floor to ceiling foam; 33” front to back (door to door); 39” side to side.

Exterior dimensions of box: 42”x36”x39” plus width of plywood on all sides.

Need longer cables to move laptop inside. ~18feet RS232 cables for CR1000, CR23X, and LRG to CR1000.
