摘要:

电阻板室的工作取决于施加在气隙内部的电场。气隙内的该电场的强度取决于诸如电极厚度、介电常数、气隙等参数。外加电场可以通过空间电荷效应得到显著的改变。这可能是在高速率粒子物理实验中工作时的一个主要问题。由于连续的雪崩而产生的空间电荷的积累可以使施加的场失真。在这项研究中,我们已经观察到,在电场中的这种扰动的强度是电荷量,电极厚度,介电常数,和气体间隙的函数。在本文中,我们已经研究了与RPC制造,上面提到的参数上的应用领域的依赖性。此外,我们还用镜像法计算了RPC基本五层结构中空间电荷引起的附加极化场。讨论了在电极厚度、介电常数、气隙三个参数相同的情况下,电场扰动的变化规律。

英文摘要:

The working of a resistive plate chamber depends on the electric field applied inside the gas gap. The strength of this electric field inside the gas gap depends on parameters like electrode thickness, permittivity, gas gap, among others. The applied electric field can get significantly modified by space charge effect. This can be a major concern while working in high rate particle physics experiments. Accumulation of space charge generated due to consecutive avalanches can distort the applied field. During this investigation, we have observed that the strength of this perturbation in electric field is a function of the amount of charge, electrode thickness, permittivity, and gas gap. In this paper, we have studied the dependence of the applied field on parameters linked to RPC fabrication, mentioned above. In addition, we have used the method of image to calculate the additional polarisation field due to space charge for a basic five layers of the geometry of an RPC. The variation of the perturbation in electric field with the same three parameters electrode thickness, permittivity, gas gap has also been discussed.
