| 摘 要： | 结合电子中微子质量测量研制高分辨率β谱仪的需要,我们开展了低能电子减速积分谱仪的实验研究。减速积分谱仪已出现多年了。五十年代哈密顿,六十年代卡德维尔,以及七十年代的赫契托等都曾作过减速栅型谱仪的工作。他们所用都是双层球栅分析栅网。赫契托用了每毫米四线的32°张角的球面栅,透射率达20%,对于200—1400eV的电子分辨率为0.06%。但前人所研究谱仪都是能量极低(2 keV以下)、尺寸较小的。为了适应中微子质量测量的要求,我们在较高能区作了实验研究。

| Abstract: | The Study of double planar grid retarding integral spectrometer for lowenergy electrons is described. The intrinsic energy resolution of double grid ismeasured by simulation of electron gun. The result shows that the resolution(FWHM) is about 2eV, which seems to be independent of the electron energy. Itis desirable to be used in the measurement of neutrino rest mass from tritiumbeta decay with an improved grid and a better geometric structure. |
