Scintillations And Microlensing [PDF]

Symposium - International Astronomical Union, 1996
It is shown how the theory of scintillation may be applied to treat gravitational lensing. The theory is applied to microlensing by a system of N point masses. It is shown that scintillation theory reproduces a known result for the angular broadening due to multiple microlensing.

Study on the Characteristics of a Scintillator for Beta-ray Detection using Epoxy Resin

EPJ Web of Conferences, 2017
A thin plate of a plastic scintillator for detecting a beta-ray was developed. The plastic scintillator was made using epoxy resin and organic scintillators such as 2.5-diphenyloxazole (PPO) and 1,4-bis [5-phenyl-2-oxazole] benzene (POPOP).
