EMR Instruments & Tools

The EMR facilities provide users with several home-built high field and high frequency (23-700 GHz) instruments. For details, click the links in the table below.

In addition to these instruments, the Magnet Lab is involved in a collaborative project to build a Free-Electron Laser at our Tallahassee facility. Please visit that page for details.

¹Absolute sensitivity is the minimum number of detectable spins per Gauss linewidth and a 1Hz bandwidth
at room temperature.
