本文介绍一系列精密晶体振荡器经受γ射线照射的计划所取得的成果。本计划的目的是要提高与核武器有关的辐射环境对上述振荡器影响方面的现有知识。主要目的是要研究一种振荡器在γ射线照射时和照射后能保持频率稳定度不变。计划主要集中在选择和使用采取精密工艺制造的“Swept”石英晶体谱振器上。半导体器件的选择也是本计划的一个重要部份。一组三个生产试捡振荡器用选择元件的办法进行改进。将这些振荡嚣放在白沙导弹靶场核试验装置里经受γ射线辐射试验。使用的照射剂量大于3×10~6拉德。在振荡器尚未停振时,频率变化小于14×10~(-8)。这表明与作同类试验的未改进的振荡嚣相比,其改进因素至少是50∶1。
This article describes the results of a series of precision crystal oscillators that are exposed to gamma rays. The purpose of this plan is to improve existing knowledge about the effects of the nuclear-related radiation environment on these oscillators. The main purpose is to study an oscillator that maintains its frequency stability constant when irradiated with gamma rays and after irradiation. The plans are mainly focused on the selection and use of “Swept” quartz crystal spectrum analyzers made using precision processes. The choice of semiconductor device is also an important part of this project. A group of three production test pick up the oscillator with the selection of components to be improved. These oscillations were placed in the Baisha Missile Range Nuclear Test Facility and subjected to gamma-ray irradiation. The radiation dose used is more than 3 × 10 ~ 6 rad. When the oscillator has not stopped, the frequency change is less than 14 × 10 ~ (-8). This shows that the improvement factor is at least 50: 1 compared to the unmodified oscillation of the same type of test.
