DC Field Magnets & Facilities

The facility contains 14 resistive magnet cells connected to a newly upgraded 56 MW DC power supply and 15,000 square feet of cooling equipment. The facility also has three superconducting magnets and an array of cryostats, dewars, probes, sample holders and other equipment. Click on the links in the tables below to see field modulation, variable field gradient, calibrations and other details about our magnets and other equipment. Also check our Magnet Dates and Deadlines list, and go to our Users Schedule page for a look at current and upcoming users.

Our top-notch team of DC field support staff keeps things running smoothly.

Resistive Magnets

All of our resistive magnets support the following research: magneto-optics (ultra-violet through far infrared), magnetization, specific heat, transport, high pressure, low to medium resolution NMR in highest fields, EMR, temperatures from 40 mK to 800 K, dependence of optical and transport properties on field orientation, and more.

Superconducting Magnets

Our superconducting magnets, listed below, are located in the Millikelvin Facility. These magnets, with a maximum sweep rate of 0.66 tesla/minute and experimental temperatures as low as 0.2 degrees K, support the following research: Magneto-optics (ultra-violet through far infrared), magnetization, specific heat, transport, high pressure, low to medium resolution NMR, dependence of optical and transport properties on field orientation and more.
