大阪大学科学工业研究所的40 MeV、L波段电子直线加速器用于各种束流科学研究。电子束或直线加速器的稳定性对于加速器的这些高级研究是至关重要的。为了从稳定性的角度评价直线加速器的性能，测量了电子枪、加速器末端和实验端口的电子束强度，并根据提供给加速器的1.3 GHz射频功率的幅度起伏分析了强度的起伏。由于加速管中的能量起伏，加速器末端的强度起伏似乎是在聚束部分产生的，而在实验端口产生的强度起伏似乎是由于加速管中的能量起伏而产生的。
The 40 MeV, L-band electron linac at the Institute of Scientific and Industrial Research, Osaka University is used for various studies on beam sciences. Stability of the electron beam or the linac is crucial for these advanced studies with the linac. In order to evaluate the performance of the linac in view of stability, the intensities of the electron beam are measured at the electron gun, the end of the linac, and the experimental port, and the intensity fluctuations are analysed based on the amplitude fluctuations of the 1.3 GHz RF power provided to the linac. The intensity fluctuations at the end of the linac seem to be produced in the bunching section and those at the experimental port to be produced owing to the energy fluctuations in the acceleration tube.
