Evaluation of methods for power calibration in large tokamaks
Aljaž Čufar, Igor Lengar, Luka Snoj
Doktorska disertacija
Oznake: nuclear fusion;fusion reactors;JET tokamak;neutron yield calibration;neutron detection;simulations;
Fusion reactors based on the fusion of deuterium (D) and tritium (T) emit large amounts of 14 MeV neutrons. As exactly one neutron is emitted per such fusion reaction, neutron yield measurements are the most direct way for the determination of the released energy. Accurate measurements of neutron ou ...

Analysis and modelling of gamma ray emission in large tokamak plasmas
Andrej Žohar, Igor Lengar, Massimo Nocente
Doktorska disertacija
Oznake: nuclear fusion;plasma physics;tokamaks;Joint European Torus;plasma transport;plasma modelling;reaction cross-section;gamma rays;
Understanding the physics of fast ions in a fusion plasma is widely regarded as one of the crucial tasks for the reliable operation of fusion tokamak reactors. Measurements on tokamaks have shown that gamma rays are produced when fast ions react either with the plasma fuel ions or with main plasma i ...

Analysis of neutron induced water activation
Domen Kotnik, Igor Lengar, Luka Snoj
Doktorska disertacija
Oznake: nuclear reactors;TRIGA reactor;water activation;experiments;KATANA facility;fusion;particle transport;
Water as a primary coolant will play an important role in the performance of fusion reactors, as after being irradiated and activated, it causes an ionising radiation field throughout the facility. Therefore, additional protection and shielding for the instruments and personnel must be adequately co ...

Characterisation of the neutron field for streaming analyses in TT operations at JET
Igor Lengar, T. Vasilopoulou, M. Kłosowski, Rosaria Villari, Bor Kos, Aljaž Čufar, Domen Kotnik, Luka Snoj, Vladimir Radulović, Žiga Štancar, Andrej Žohar
Izvirni znanstveni članek
Oznake: jedrska fizika;
Assessing radiation fields in the biological shield penetrations of fusion reactors is a challenging task. At the Joint European Torus (JET) the neutron field at larger distances from the torus has been calculated and measured. JET operated in 2021–22 with a tritium-tritium plasma and neutronics exp ...

A real-time architecture for the identification of faulty magnetic sensors in the JET Tokamak
A.C. Neto, D. Alves, B. B. Carvalho, G. De Tommasi, R. Felton, H. Fernandes, P.R. Lomas, F. Maviglia, F.G. Rimini, F. Sartori, Adam V. Stephen, D. F. Valcárcel, L. Zabeo, Igor Lengar, Luka Snoj
Izvirni znanstveni članek
Oznake: jedrska fizika;fizika plazme;
In a tokamak, the accurate estimation of the plasma boundary is essential to maximise the fusion performance and is also the first line of defence for the physical integrity of the device. In particular, the first wall components might get severely damaged if over-exposed to a high plasma thermal lo ...
