Ingår i: NUCLEAR FUSION. - 0029-5515. ; 39:3, s. 321-336
-
Tidskriftsartikel (refereegranskat)abstract
- Reactor relevant ICRH scenarios have been assessed during DT experiments on the JET tokamak using H mode divertor discharges with ITER-like shapes and safety factors. Deuterium minority heating in tritium plasmas was demonstrated for the first time. For 9

Ingår i: REVIEW OF SCIENTIFIC INSTRUMENTS. - 0034-6748. ; 70:1, s. 1176-1180
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Spectrometry of the neutron emission is discussed as a probe of the fuel ion velocity distribution in tokamak plasmas where the instrumental energy calibration allows determination of Doppler shifts on an absolute scale or relative to the emission of ther

Ingår i: Plasma Physics and Controlled Fusion. ; 40, s. 1211-1219
-
Tidskriftsartikel (refereegranskat)abstract
- The first measurement of the energy distribution of the neutron emission from the nuclear burn-up of tritons produced at 1 MeV in d + d --> t+p reactions is reported. The results refer to deuterium plasmas with a strongly pulsed neutron production attaine

-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The first magnetic proton recoil type neutron spectrometer has been put to use for diagnosing tokamak plasmas of high neutron yield rates (the range Y-n = 10(15)- 6 x 10(18) n/s). The spectrometer principles along with the diagnostic installation are pres

Ingår i: REVIEW OF SCIENTIFIC INSTRUMENTS. - 0034-6748. ; 70:1, s. 1171-1175
-
Tidskriftsartikel (refereegranskat)abstract
- Spectrometry of the neutron emission has been used to probe the nonthermal features of the fuel ion velocity distributions in tokamak plasmas, especially, those arising from auxiliary heating. The first time resolved measurements are reported from the use

-
Tidskriftsartikel (refereegranskat)abstract
- The wall emission (WE) background accompanying observations of fusion plasma neutrons is a limiting factor in high accuracy neutron diagnostics. It is an important issue to solve for envisaged burning plasma experiments such as with ITER. This work repres

-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The fast alpha-particle kinetic effects in fusion plasmas of deuterium and tritium are studied in the perspective that they can give rise to minority populations of fast fuel ions. The resulting modification of the neutron emission spectrum is computed fo

-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The neutron energy spectrum from d+t and d+d reactions in a thermonuclear fusion plasma is investigated with the help of a combination of analytical and numerical (Monte Carlo) methods. The energy moments of the neutron spectrum are analytically determine
