采用提升法成功地制备了单晶化学气相沉积金刚石。将其制成辐射探测器,在聚变中子源上进行了14 MeV中子的响应函数测量。用(12)C(n,α)(9)Be反应获得了1.5%的高能量分辨率。本征能量分辨率为0.79%,这也是迄今报道的最好的钻石探测器分辨率,其中不包括中子散射、目标减速和电路噪声引起的能量扩散。
A self-standing single-crystal chemical vapor deposited diamond was obtained using lift-off method. It was fabricated into a radiation detector and response function measurements for 14 MeV neutrons were taken at the fusion neutronics source. 1.5% of high energy resolution was obtained by using the (12)C(n, α)(9)Be reaction at an angle of 100° with the deuteron beam line. The intrinsic energy resolution, excluding energy spreading caused by neutron scattering, slowing in the target and circuit noises was 0.79%, which was also the best resolution of the diamond detector ever reported.
