Interplanetary scintillation, fluctuations of radio waves caused by the solar wind
The scientific activities of Boris Grinyov center on the study of the fundamental properties of scintillation materials: searching for new scintillators, and developing instruments and devices based on scintillators for applications in various fields ranging from high energy physics (the BaBar, Belle and Alice experiments and the Fermi Gamma-ray Space Telescope, among others) to medical devices.
Two photomultiplier tubes are used to detect the scintillation light produced by a particle interacting with the argon.
At a time when electronics had not been able to make measurements with nanosecond accuracy, he developed several techniques to accomplish this accuracy for measuring organic fluorescence decay times and organic scintillation pulse widths by indirect means.
