600 MHz Progress…

The 600 MHz is being prepared for energizing to field.  First, the vacuum insulation is pumped down with turbo pumps to achieve a high-vacuum (~10-8).



Today, the liquid nitrogen tank is being cooled and filled.  The liquid helium chamber is being pre-cooled to N2(l) temperature.  Tomorrow they will cool and fill the liquid He chamber with He(l).



Once cooled, the magnet can be slowly energized and brought to field.  This system will require ~5 hrs to energize (assuming no quench), compared with 5-8 days for the 850 MHz.  Once energized, they will spend a day shimming the cryo-temp shims.  The magnet will need a few wks to settle – during this time the console will be installed and tested.
