Heavy Ion Beam Probing (HIBP) diagnostic is a powerful tool for electric field studies in the hot dense plasma of modern-day toroidal magnetic confinement devices. On the TUMAN-3M tokamak, the HIBP have been used in regimes with improved plasma confinement to clear up the role of the radial electric field in the transition to good confinement regim...

Conference Paper
Radial electric field shear is crucial for turbulence suppression and transition to the H-mode, although the high shear value alone may not be sufficient for the LH-transition initiation. Temporal and spatial parameters of shear perturbation, particle source and turbulence parameters are the main factors responsible for LH-transition initiation. Di...

... To support measurements of fast ion distributions provided by the NPAs, a neutron dump (ND) installed behind the LENPA analyzer is equipped with neutron and gamma spectrometers (see figure 4) [20,21]. The main task of the Gamma-Ray Spectrometer (GRS) is providing data on the energy distribution of alpha particles in the energy range 1.7-3.5 MeV obtained from measurements of 4.44 MeV line emission generated in the 9 Be(α, nγ) 12 C reaction. ...
