12 T Dry Cryomagnet

• Integrated 50 mK Dilution Refrigerator and GHS

• +/- 12 T symmetric vertical field

• 35mm split

• +/- 4-degree beam divergence

• Dark Angle: 40 degrees

• Dil Fridge 60+ microWatt minimum cooling power @100 mK


09/08/22 Update:

installation of the radiation shield and outer chamber is 

being completed

• These are the final steps of closing the cryostat for the 

preliminary test

• System cooldown is expected for week of Sept 12th

• DR status:

• Machining: 95% complete (ULT parts only remain)

• Still : completed

• 1K pot : 85% assembled

• Mixing chamber : 50% complete

• ULT : Sub-assemblies started

• Heat exchangers : 80% complete
