Liquid Scintillation Detectors for Gamma and Neutron Diagnostic at Textor and Results of Runaway and Sawtooth Oscillations
Time and energy resolved neutron and gamma measurements are performed at the TEXTOR tokamak with a fast liquid NE-213 scintillator. To distinguish between neutron and gamma (gamma)-ray induced events, pulse shape discrimination is used. To suppress scattered radiation, the detector is installed in well-shielded collimators aligned radially or tangentially to the plasma current. Count rates up to 2-3 x 10(5) s(-1) can be processed without considerable reduction of n/gamma discrimination and without gain instability. To demonstrate the capability of this system, typical results are presented as obtained from plasmas in TEXTOR during sawtooth oscillations, runaway discharges, pellet injection, and neutral beam injection
