Pending Issues
- The magnet seems not to work reliably with the lambda stage
(2 quenches during an expt. in Decemper 2006). One
problem is that the switch heater power seems to be too low.
In a test in February 2007 no more problems were seen.
- The magnet has a cold leak, occuring only occasionaly at low temperatures.
As a workaround the main vacuum has to be pumped constantly. (Oct 2006)
Solved issues
- There seem to be a problem with the He level gauge. As a workaround, an
additional gauge is placed in the He filling port. (2005-10-19)
Solved in winter 2006.
