Diagnostics modules for tokamak disruption experiments
- North Carolina State Univ., Raleigh, NC (United States)
Diagnostic modules equipped with various sensors can provide useful information on key parameters for disruption events, e.g. energy deposition, vapor shielding effect, plasma pressure and force distribution. The modules are, basically, DIMES samples (Divertor Materials Evaluation System) equipped with sensors, coupled to digitizing units and interfaced to a data acquisition system. The DIMES samples are part of the lower diverter diagnostics on the DIII-D tokamak. Three top-cap prototype diagnostics modules have been designed and fabricated. The initial testing and calibration have been performed using the SIRENS plasma gun at an energy deposition of 1 to 12 MJ/m{sup 2} over 0.1 to 1.0 ms, with a plasma pressure >100 MPa.
