Unfolding of energies of fusion products measured by the activation probe at JET
 Ficker, Ondřej ; Mlynář, Jan ; Bonheure, G. ; Murari, A. ; Popovichev, S.
Providing a detection method for diagnostic of charged fusion products in tokamaks presents a major challenge, while its absolute calibration with a sufficient accuracy and its capability to withstand harsh fusion reactor environment will be required. A novel type of detector that meets most of these requirements, based on an activation probe, was tested in JET and other European facilities. This probe proved to be extremely robust due to its simple construction. It is equipped with samples of well defined isotopic abundance. The amounts of activated nuclei due to the reactions in these materials could be measured via ultra-low-level gamma spectroscopy. The feasibility of the proton spectrum reconstruction from measured activities is examined in this contribution with the help of the algorithm based on the Tikhonov regularisation constrained by minimum Fisher information. The reliability of the method was previously illustrated using synthetic proton data.

Status of Development of High Temperature Radiation Hardened Hall Sensors for Energy Producing Fusion Devices
 Kovařík, Karel ; Ďuran, Ivan ; Sentkerestiová, J. ; Oszwaldowski, M. ; Viererbl, L. ; Boshakova, I. ; Holyaka, R. ; Erashok, V.
A principally new diagnostic method has to be developed to allow the magnetic measurements in true steady state regime of operation of future fusion reactors. One of the options is use of diagnostics based on Hall sensors that are well established in experimental physics and industry. There are two main issues associated with the use of Hall sensors in harsh environment of future fusion reactors. They are low survival temperature of available commercial transducers and unreliability of these mostly semiconductor sensors under neutron irradiation. This paper describes status of development of sensors to be operational in conditions mentioned above.
