Abstract

The work describes a one-dimensional detector for diffraction experiments at a synchrotron radiation beam. The detector is being developed at the Budker Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences. Until recently the institute was developing gas one-coordinate detectors, in particular a one-coordinate detector with calculated channels (OD-3M), based on the technology of multiwire proportional chambers. To provide a spatial resolution better than 100 microns at a photon energy in a wide energy range (3–30 keV), it is necessary to use solid-state microstrip or matrix sensors in combination with specialized integrated registration circuits. The developed SOCOD detector, using a microstrip sensor based on gallium arsenide as a registration element, operates in the mode of the direct counting of photons with an energy of more than 3–4 keV and a speed of up to 1 MHz/channel. The work gives a general description of the current version of the detector, a block diagram of the registration channel, the software allowing users to control the operation of the detector and display the results obtained, and the developed algorithm for leveling the trigger thresholds in the channels. The results of electronic tests, the work of the alignment algorithm and their discussion are presented.

用于同步辐射束衍射实验的一维探测器的研制

摘要

该作品描述了一种用于同步加速器辐射束衍射实验的一维探测器。该探测器正在俄罗斯科学院西伯利亚分院巴德克核物理研究所研制。直到最近，该研究所还在开发气体一坐标探测器，特别是基于多线比例室技术的具有计算通道的一坐标探测器（OD-3M）。为了在宽能量范围（3-30 keV）的光子能量下提供优于 100 微米的空间分辨率，有必要将固态微带或矩阵传感器与专门的集成配准电路结合使用。开发的SOCOD探测器，使用基于砷化镓的微带传感器作为记录元件，工作在直接计数光子的模式下，能量超过3-4 keV，速度高达1 MHz/通道。这项工作对当前版本的检测器、注册通道的框图、允许用户控制检测器的操作并显示获得的结果的软件、以及用于调平触发阈值的开发算法进行了总体描述。渠道。介绍了电子测试的结果、对准算法的工作及其讨论。以及开发的用于调平通道中触发阈值的算法。介绍了电子测试的结果、对准算法的工作及其讨论。以及开发的用于调平通道中触发阈值的算法。介绍了电子测试的结果、对准算法的工作及其讨论。
