RISDevelopment of a Bonner sphere spectrometer with emphasis on decreasing the contribution of scattering by using a new designed shadow cone
In this study, the Bonner sphere spectrometer (BSS) used for measurement of neutron spectra based a BF3 long counter. The most important problem for this system was a high count of scattered neutrons. This spectrometer was ...
Evaluation of response matrix of a multisphere neutron spectrometer with water moderator
Neutron energy responses of water sphere spectrometers (WSS) to 30 MeV have been
calculated by means of Monte Carlo calculations, using the computer code MCNP4C with ENDF/B-VI.0 neutron cross-section. The calculations ...
MEASUREMENT OF THE NEUTRON SPECTRUM BY THE MULTI-SPHERE METHOD USING A BF3 COUNTER
The multi-sphere method, a neutron detection technique, has been improved with a BF3 long
cylindrical counter as a thermal detector located in the center of seven spheres with a diameter
range of 3.5 to 12 ...
ارزیابی جنس، اندازه و تعداد کره های بانر و محاسبه تابع پاسخ انرژی سیستم به همراه آشکارساز BF3
درطیف سنجی نوترون به روش کره های بانر پس از شمارش توسط هریک از کره ها در مقابل چشمه، جهت بازیابی طیف اندازه گیری شده و رسیدن به طیف واقعی چشمه بایستی تابع پاسخ انرژی آنها را نیز در اختیار داشت. یکی از بهترین روشهای بدست ...
