EMR Instrumentantion Capabilities
The EMR facilities provide users with several home-built high field and high frequency (23 GHz - 1 THz) instruments. For details, click the links in the table below.
In addition to these instruments, the EMR program is involved in several facility development projects, including a collaborative effort to build the "Big Light" Free-Electron Laser.

1The absolute sensitivity is the minimum number of detectable spins per mT linewidth and a 1 Hz bandwidth at room temperature.
2 In combination with a far-infrared laser, selected frequencies up to 2500 GHz are available.
