Filled BUBBA with about 30 liters of liquid helium yesterday. The fill went smooth and took about 25 minutes. Julie and Yongjae assisted with the fill.

SI-4 AF Demagnetizer -- FIXED

The SI-4 AF Demagnetizer is up and running. The PA04 power amplifiers burnt out (failed) because of insufficient air flow. The air filter was clogged with lint and dust. The air filters are easily removed and need to be cleaned out about every 6 months with water. In case of another power failure, the PA04 power amplifiers can be purchased from Apex utech volume 7 price list.
