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 presented. Performance and diagnostic capabilities are illustrated based on results obtained at Joint European Torus. The implications for neutron spectrometry diagnostics on the next step tokamak for burning plasmas (Y-n --> 10(22) n/s) are discussed

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 presented. Performance and diagnostic capabilities are illustrated based on results obtained at Joint European Torus. The implications for neutron spectrometry diagnostics on the next step tokamak for burning plasmas (Y-n --> 10(22) n/s) are discussedFile in questo prodotto:
