【摘要】 本文详细介绍了Micromegas探测器的基本结构、原理以及近期来本所最新实验进展:不同工作气体（Ar和CO₂）配比条件下,利用⁵⁵Fe放射源对该探测器的能量分辨、计数曲线和气体增益等特性进行了较为详尽的测试。除此,文章还对增益的实验结果和Garfield的模拟结果进行了比较。更多还原

【Abstract】 In this paper,we describe the structure of Micromegas（Micro Mesh Gaseous Structure） detector which has been developed recently by our group.And its gas gain,energy resolution and signal in the condition of a ⁵⁵Fe X-ray source and various Ar-CO₂ mixtured gases are plotted as a function of mesh voltage.The results using Garfield program of simulation of the Micromegas detector are very important to optimize the design,shorten the experimental period.Additionally, they also indicate theat the Garfield program is a powerful tool for the Micromegas detector design and experiment.更多还原
