3. Cherenkov detectors as an auxiliary diagnostic for the studies of the runaway-electrons beams recorded in the tokamak’s Scrape-Of-Layer

Roch Kwiatkowski (National Centre for Nuclear Research)

Talk

The NCBJ team had proposed to use Cherenkov detectors with diamond radiators for measurements of fast electrons inside the Magnetic Confinement Facilities of the tokamak type many years ago. The main idea was the application of a Cherenkov Effect for measurements of electron-beams in the energy range of (50-300) keV. In MCF the studies were performed for runaway electrons that undergo...

2. Numerical reconstruction of Langmuir probe measurements obtained from the negative ion source for ITER (SPIDER)

Prof. Roman Zagorski (National Centre for Nuclear Research)

Keynote

The experimental fusion reactor ITER will be heated by injection of a fast neutral beam generated by acceleration and neutralization of negative ions. The negative ion source used for this purpose (SPIDER), constructed at the Consorzium RFX (Italy) consists of 8 driver volumes where radio-frequency (RF) power is inductively coupled to the plasma electrons and an expansion chamber containing a...

4. Review of optical emission spectroscopy applications of the plasma and the PFC materials interaction study in Plasma-Focus and Rod Plasma Injector devices

Dobromił Załoga (National Centre for Nuclear Research)

Talk

This overview presents a study of the plasma interaction with the plasma-facing components (PFC) materials in the Plasma-Focus (PF) and the Rod Plasma Injector (RPI) devices using optical emission spectroscopy (OES). The mentioned devices generate intense plasma streams, but they differ in operational parameters. The measurements were performed using PF-360 (NCBJ), PF-1000U (IFPiLM) and...
