We have had the fortunate ability to develop the sub-systems independently. Each system has unique demands to work cryogenically. The magnet requires hundreds of amps to be delivered at 4 Kelvin, all while being cooled exlcusively through conduction mechanisms. For the readout development, we have had to design and commision a custom cryostat with a base temperature of 270 milli-Kelvin, as well as integrate testing equipment into a Dilution Refrigerator for device testing that requires the 10 milli-Kelvin base temperature.</p>
