论文摘要
通过使用塑料闪烁探测器在加尔各答Bose Institute的高能量物理探测器实验室中使用塑料闪烁探测器来测量宇宙射线MUON通量。由于COVID19爆发和全国范围内的封锁，该实验室从2020年3月底至2020年5月底关闭。锁定后，尽管该市不处于正常状态，但我们仍然可以在几天的时间内获取数据。锁定对紧急情况以外的运输服务以及大多数行业都在城市及其周围施加了严格的限制。在空气污染物浓度的变化方面，这种锁定对大气条件有重大影响。我们已经测量了锁定之前和之后的宇宙射线通量，以观察出明显的变化，如果由于大气条件的变化而发生了明显的变化。在本文中，我们报告了加尔各答的宇宙射线通量（22.58 $^{\ circ} $ n 88.42 $^{\ circ} $ e和11〜m海平面的11〜m以及在锁定之前和之后存在的主要空气污染物。
Cosmic ray muon flux is measured by the coincidence technique using plastic scintillation detectors in the High Energy Physics detector laboratory at Bose Institute, Kolkata. Due to the COVID19 outbreak and nationwide complete lockdown, the laboratory was closed from the end of March 2020 till the end of May 2020. After lockdown, although the city is not in its normal state, we still were able to take data on some days. The lockdown imposed a strict restriction on the transport service other than the emergency ones and also most of the industries were shut down in and around the city. This lockdown has significant effect on the atmospheric conditions in terms of change in the concentration of air pollutants. We have measured the cosmic ray flux before and after the lockdown to observe the apparent change if any due to change in the atmospheric conditions. In this article, we report the measured cosmic ray flux at Kolkata (22.58$^{\circ}$N 88.42$^{\circ}$E and 11~m Above Sea Level) along with the major air pollutants present in the atmosphere before and after the lockdown.
