Duplex magnet to help meet demand for high fields

This week at the lab, we're preparing a home for a new magnet that will give more scientists access to some of the highest magnetic fields in the world.

The new Duplex Magnet, slated for completion this fall at the Pulsed Field Facility in Los Alamos, New Mexico, will reach fields up to 80 teslas, although it will most often run at 75 teslas to extend its lifetime. Like the other instruments available at the Pulsed Field Facility, the Duplex will generate these incredibly high fields for just a fraction of a second — still ample time for physicists to get valuable data.

But unlike the facility’s other magnets, the Duplex features two coils that will be powered by separate circuits and capacitors. This design helps operators better manage the temperature and stress the instrument is subjected to and allows for flexibility in future improvements.

The Duplex will be located near the facility’s primary workhorse, the 65 Tesla Multi-Shot Magnet. Featuring the same 15-millimeter bore for inserting experiments, it will enable more scientists to do cutting-edge experiments in these extreme fields.
