摘要
使用由空气层(1 号辐射器)或聚四氟乙烯层(2 号辐射器)(厚度 b = 100 μm)隔开的薄铝箔堆(厚度 a = 10 μm),对能量范围为 8 至 200 keV 的共振过渡辐射(RTR)进行实验观测的结果。两个辐射器的周期都是固定的(d = a + b = 110 μm)。在研究的能量区间内,辐射器 1 的辐射形成长度大于周期,而辐射器 2 的辐射形成长度小于周期。对于前者,我们观察到实验与理论之间存在合理的一致性,但对于后者,我们观察到一些差异。
Observation of X-ray transition radiation from a relativistic electron passing a stack of plates
The results of experimental observations of resonant transition radiation (RTR) with energies ranging from 8 to 200 keV using stacks of thin aluminium foils (thickness a = 10 μm) separated by layers of either air (radiator no. 1) or Teflon (radiator no. 2) (thickness b = 100 μm). Period of both radiators was fixed (d = a + b = 110 μm). For the studied energy interval, a radiation formation length was larger than period for radiator 1 and was less for radiator 2. For the previous one we observed a reasonable agreement between experiment and theory, but for the latter one we observed some discrepancy.
期刊介绍:
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
