在室温下运行的两个天然钻石探测器（NDDS）用于融合中子源（FNS）氘 - 三位生（DT）中子光谱测量在Tritium靶标周围的不同点和不同的Deuteron束能量。 ，值1.95％和2.8％。能量分布及其在目标内部散射引起的范围。对于基于NDD的光谱系统和0.25μs的成型时间放大器，以5.7×105计数的计数速率测量。基于NDD的光谱法所需的计数速率约为106/s。
Two natural diamond detectors (NDDs) operating at room temperature were used for Fusion Neutronics Source (FNS) deuterium–tritium (DT) neutron spectra measurements at different points around the tritium target and for different deuteron beam energies. Energy resolution of both NDDs were measured, with values 1.95% and 2.8%. Due to the higher energy resolution of one of the two NDDs studied it was possible to measure the shape of the DT neutron energy distribution and its broadening due to deuteron scattering inside the target. The influence of pulse pileup on the energy resolution of the combined system (NDD+electronics) at count rates up to 3.8×105 counts/s was investigated. A 3.58% energy resolution for the spectrometric system based on NDD and a 0.25 μs shaping time amplifier has been measured at a count rate of 5.7×105 counts/s. It is shown that special development of a fast pulse signal processor is necessary for NDD based spectrometry at count rates of approximately 106 counts/s.
