Helium dewars: 1,000 liters, 500 liters, 50 liters = 1,550 L 

¼ CM LHe capacity, ~ 400 L (?)

Total LHe supply from CTF….

Nitrogen line at 80 psi thru a 3/8 inch pipe = 22 cfm or 1,320 cubic feet per hour

SF6 inside vessel that hold HV power supply: 25 ft3 filled to 70 psi, ~ 54 lbs: total volume if released? 144 ft3

HDIce gets power from Big Bertha. Big Bertha will get power fed from a distribution panel in the annex. This distribution panel is attached to the generator. Ground isolated linesWalt thinks we might want two additional 480 VAC welding receptacles installed inside the cave too. These additional lines do not need to be attached to a generator.

Walt: electronics racks platform design, for Neil to build

Neil Wilson: rack platform, unistrut to wall, temporary stairs, LCW, GN2 and compressed air

Layout of utilities added to unistrut

Have facilities remove stuff from control room wall exterior

Find a concrete block for empty space near control room

Have Walter move concrete block…
