Thursday, December 05, 2013
Impedance measured on TGHT and TBHT (~2.5 mOhm and ~2.0 mOhm). Readback on TBHT gives an impedance of ~2.5 mOhm. This is higher than the previous test. Local current on TBHT shows 60A more than the readback at 300A. The vacuum did not come down as low as usual, which likely means there is a leak.
