Soft x-ray measurements on the PLT Tokamak

6

TL;DRAbstract

Four experiments are described that currently run on the PLT tokamak and which utilize the soft x-ray emission of the plasma as a diagnostic: the pulse height analysis system for temperature and impurity measurements; the curved crystal Bragg spectrometer for the determination of ionization states of impurities; ''windowless'' surface barrier detectors for the investigation of the ultra soft x-ray radiation in the energy range 0.1 keV < h..nu.. < 1 keV and a silicon diode array for x-ray fluctuation measurements. For each diagnostic a short technical description and some recent results obtained with it on PLT are given in order to demonstrate its use.
