The selected works and presentations of Amur Margaryan

The selected works and presentations of Amur Margaryan focus on the development of high-precision timing technologies based on radio-frequency (RF) methods. A new-generation sensor, the Radio-Frequency Photo Multiplier Tube (RF PMT), has been developed and tested, enabling the detection of electrons and photons with picosecond-level precision. The technique is based on circular scanning of electrons and position-sensitive detection, whereby temporal information is transformed into a spatial distribution.
