Radio Frequency Timer based Electron, Photon and Heavy Ion Detectors

Project Status: 6 Project underway
Commencement Date: 01.03.2024
Duration in months: 0 months


Within the scope of this project, it is proposed to develop, create and test detectors of single electrons, photons and heavy ions based on the advanced Radio Frequency (RF) timer created as a result of the implementation of the ISTC projects A-372 and A-2390. Test studies of the advanced RF timer with the RF synchronized femtosecond laser beam demonstrated ?10 picoseconds (ps) time resolution and 0.2 ps/hour stability. This 10 ps resolution is not a technical or physical limit, it is mainly due to the technical parameters of the prototype tube and RF deflector and can be reduced to the ps and sub-ps level by suitable optimization of those parameters. The project has three main objectives. First, to improve the time resolution of the RF Timer created in the framework of the ISTC A2390 project, aiming to bring it from 10 ps to 1 ps. Second, to develop, construct and test of the 500 MHz RF timer based heavy ion detectors and operate them with RF driven particle beams. Third, to develop, construct and test a dedicated RF deflectors of keV energy electrons, capable to operate in the 1-10 GHz frequency range.
