Development of Dual-phase Xenon TPC with a Quartz Chamber for Direct Dark Matter Search

Posted by klaurent Tokyo

Kavli Affiliate: Masaki Yamashita | Summary:The idea of a hermetic quartz chamber in a dual-phase xenon time projection chamber (TPC) has the potential to improve the detector sensitivity for direct dark matter searches in the future. A major challenge facing TPC detectors in future dark matter experiments will be the reduction of the internal background […]

Line Expansion Opacity in Relativistically Expanding Media

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li |Summary:Spectral lines of heavy atomic elements in the ejecta of supernovae and neutron star mergers can have important contribution to the opacity of the ejecta matter even when the abundance of the elements is very small. Under favorable conditions, the line expansion opacity arising from spectral lines and the expansion […]
