Diagnostic Development for the WHAM Device

The Wisconsin HTS Axisymmetric Mirror (WHAM) device anticipates fusion relevant densities and temperatures enabled by the combination of new high-field magnet technology, high harmonic fast wave (HHFW) heating of neutral beam fast ions, ECRH heated electrons confined by magnetic expanders, and vortex shear stabilization of MHD instabilities. An overview of the plasma diagnostics in development and how they are incorporated in the vessel will be presented, including: 1. Flux loop and magnetic pick-up coils, 2. mm-Wave interferometry, 3. Soft X-ray spectroscopy, 4. Fusion neutron detectors, 5. D-$\alpha$ arrays, 6. Fast neutral particle and RGA measurements, 7. Visible and IR imaging, and 8. Fusion proton detectors. Diagnostics provided by collaborators (Thomson scattering and Zeeman measurements from ORNL), will also be included, as well as future diagnostics under development.
