【摘要】：PandaX是一個位于四川錦屏地下實驗室的大型粒子與天體物理稀有事件探測實驗裝置。PandaX的一期和二期實驗利用二相型氙時間投影室技術(shù)來直接探測弱相互作用暗物質(zhì)粒子。PandaX一期實驗已經(jīng)完成,它使用了120 kg氙以檢驗以往其他實驗所發(fā)現(xiàn)的疑似信號,其結(jié)果在標準假設(shè)下否定了這些疑似信號。PandaX二期升級了探測器,使用了500 kg的氙,預(yù)期在2015年晚些時候正式開始數(shù)據(jù)采集以尋找暗物質(zhì),將有望拓展暗物質(zhì)探測的極限。
[Abstract]:PandaX is a large particle and astrophysical rare event detection experimental device. PandaX is located in Jinping underground laboratory in Sichuan Province. The first and second phase experiments use two-phase xenon time projection chamber technology to direct the experiment. The first phase of the experiment to detect the weakly interacting dark matter particle, PandaX, has been completed. It used 120 kg of xenon to test suspected signals found in other previous experiments, and the results negated those suspected signals under standard assumptions. PandaX II upgraded the detector. Using 500 kg of xenon, it is expected that the official start of data collection in the search for dark matter later in 2015 is expected to expand the limits of dark matter detection.
