Contact Jerry Makara (makara@fnal.gov), asking to send the gHe Tube-Trailer to NM4. cc Kun(liu.pku@gmail.com), Dustin (dustin@virginia.edu).
We should also estimate the number of tubes needed and how long we are expected to keep the trailer at NM4.
Based on our records:
1. If we are getting the tubes with 900 psi in each tube, then one tube adds ~4-5 psi in the outside tank (see http://twist.phys.virginia.edu:8081/General/1089)
2. If we are getting the tubes with 1800 psi in each tube, then one tube adds ~7-8 psi in the outside tank (see http://twist.phys.virginia.edu:8081/General/838)
