The NIST-SANS Electromagnets (HM1 and HM2)
There are three electromagnets that are used on SANS. One can achieve up to 1.8 Tesla (forefront of picture) with the magnetic field perpendicular to the neutron beam. Another can achieve up to 0.5 Tesla with the magnetic field either parallel or perpendicular to the neutron beam. The 0.5 Tesla magnet can be adapted to accomodate any of our closed cycle refrigerators, and is now possible to reach temperatures of 2K or less. The third can also reach 0.5 Tesla, and is commonly used at BT5 USANS.
