The conductivity of the TGHT circuit will be measured with a copper bar shunt.

Monday, December 02, 2013, 16:00: Pumping down. 

Tuesday, December 03, 2013, 09:40: Stepped current up to 600A. Impedance of system ~0.7 mOhm. See attached graph for P(I).

Tuesday, December 03, 2013, 12:06: Stopped turbo. Vacuum at 1.3E-5 Torr

Wednesday, December 04, 2013, 09:20: Copper bar removed from vacuum chamber.

Test finished.
