TEXT-U Interferometer

The TEXT-U vertical view interferometer consists of an array of 15 detectors measuring interferometer phase data at 432 µm. (D. Brower, UCLA)

These detectors are spaced 3 cm apart and extend from -17.2 cm to 24.8 cm.

Tomographic imaging techniques are employed during periods of rigid body rotation to provide detailed two dimensional images of the plasma density profile.

Polarimetry data generated from Faraday rotation is also collected from the vertical view imaging system.

The plasma diagnostics group at UC Davis is developing inversion codes to recreate the electron and current density profiles from line integrated data collected at TEXT-U.
