由于加尔各答的COVID19，Cosmic ray流量和封锁--有任何相关性吗？
Cosmic ray flux and lockdown due to COVID19 in Kolkata -- any correlation?
摘要：
在加尔各答玻色研究所的高能物理探测器实验室中，利用塑料闪烁探测器的符合技术测量了宇宙线μ介子通量。由于COVID-19爆发及全国全面封锁，实验室于二零二零年三月底至二零二零年五月底关闭。封锁后，虽然城市不处于正常状态，但我们仍然能够在某些日子获取数据。封锁对除紧急服务外的运输服务施加了严格的限制，城市内外的大多数工业也被关闭。就空气污染物浓度的变化而言，封锁对大气状况有重大影响。我们已测量了封锁前后的宇宙射线通量，以观察大气条件变化是否会引起明显变化。在这篇文章中，我们报告了在加尔各答（22.58 $^{\circ}$ N 88.42 $^{\circ}$ E和海拔11米）测量的宇宙线通量以及封锁前后大气中存在的主要空气污染物。
英文摘要：
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.
