Abstract

A-TOF is a novel time-of-flight device under construction for high-resolution spectroscopy of alpha-particle emission energies originating from the natural decay of heavy nuclides. It detects the time difference between pulses generated by the alpha-particle in a fly-through start-timing detector and in a stop-timing detector at several meters distance. This paper discusses the design of the start-timing detector and expands on details of its construction, including the electrostatic mirror, electron detector, and fast signal amplifier. Estimates are made about the anticipated timing resolution. The aim is to improve the energy resolution well below the physical limit of planar ion-implanted silicon detectors.

a - tof设备启动时间检测器的设计

a- tof是一种新型的飞行时间装置，用于高分辨率光谱分析源自重核素自然衰变的α粒子发射能量。它可以在几米远的距离上，在一个飞行开始计时探测器和一个停止计时探测器中检测到由α粒子产生的脉冲之间的时间差。本文讨论了启动定时检测器的设计，并详细介绍了其结构，包括静电镜、电子检测器和快速信号放大器。对预期的时间解决方案进行估计。其目的是提高能量分辨率，使其远远低于平面离子注入硅探测器的物理极限。

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
