“…Therefore, (Hindié et al 2002) recommended that the medical use of 131 I should not be performed in children. In addition, it was observed that the toxicity of 131 I when entering the organisms through inhalation is higher than ingestion (Luchanskii et al 1988). Therefore, the route of exposure to 131 I could play a significant role in developing radiation-induced thyroid cancer.…”

“…Two NDDs [12][13][14][15] with the NDD can be constructed in a relatively simple manner. Energy spectrum measurement can be accomplished with just one detector using the pulse height analysis (PHA) mode with a combination of fast amplifiers, ADC and histograming memory.…”

Study of ripple-trapped proton behaviour in LHD by two line-of-sight measurements of fast neutrals

et al. 2004

The behaviour of helical ripple-trapped particles in large helical device (LHD) have been investigated by two line-of-sights natural diamond detector measurements in plasma sustained with ICRF for two types of resonance configurations, i.e. on-axis and saddle-shaped resonances. The tail temperature increases linearly as the Stix-temperature increases and then saturation follows, indicating the effect of the finite confinement time of the energetic ions. In the linear region, the tail readily increases when the line-of-sight is focused on the larger resonance area. The confinement time of the energetic ions is obtained from the empirical relation based on the Stix theory. The configuration with a saddle-shaped resonance has a longer confinement time than the on-axis resonance. Analyses of experimental measurements are consistent with the theoretical calculations including collisional ripple-induced transport.

“…This article describes an experimental study of heating efficiency and the sawtooth induced redistribution and subsequent stochastic ripple diffusion of energetic protons during central and off-axis H + minority ICRH on TFTR. Data about confined proton behaviour obtained by a natural diamond detector (NDD) [15][16][17] based charge exchange atom spectrometer [18] are compared with the evolution of fast proton losses measured by three escaping charged particle detectors [19]. In Section 2 we briefly review the experimental technique.…”

Study of acceleration, confinement and sawtooth induced redistribution of fast resonant protons during ICRH in TFTR

et al. 1999

A natural diamond detector (NDD), developed in the Russian Federation, has been used for the first time for fast charge exchange H0 atom spectrometry and flux evolution measurements during H+ minority ICRH experiments in deuterium plasmas in TFTR. The behaviour of deeply trapped RF driven H+ ions was studied in quiescent plasmas and under the influence of sawtooth oscillations during central and off-axis ICRH. H+ ion energy spectra measured by the NDD yielded data on the efficiency of H+ minority ion acceleration by ICRF waves and the H+ ion confinement at different ICRH powers and resonance layer positions. The evolution of the hydrogen charge exchange atom flux measured by the NDD was compared with fast proton losses measured by escaping charged particle detectors to demonstrate that fast H+ ions are redistributed from the plasma core to well beyond the q = 1 surface. The redistribution is sufficiently far from the plasma centre for fast ions to leave the plasma due to stochastic ripple diffusion. In contrast with non-deeply-trapped fast ions, Alfvén eigenmode (AE) activity does not significantly affect the spatial and energy distributions of deeply trapped fast ions.
