At present the number of large and compact neutron spectrometers is under development for application in fusion plasma experiments. Compact neutron spectrometers have a very high potential to be used in future fusion devices, and in ITER in particular, due to their ability to be placed inside narrow collimators of multi-channel neutron cameras providing the spatially resolved neutron spectrometry. Stilbene neutron detectors were successfully used for D-D neutron flux measurements on Tore-Supra and JT-60U and neutron spectrometry and flux measurements on neutron generators. Results of measurements of DD and DT neutron spectra using compact stilbene neutron detector during 2003 Trace Tritium Experiments (TTE) at JET are presented in this paper.
