Development, Calibration and Application of New-generation Dissector with Picosecond Temporal Resolution

摘要

A dissector is an electron-optical device designed for measurement of periodic light pulses of subnanosecond and picosecond duration. LI-602 dissector developed at Budker Institute of Nuclear Physics (BINP SB RAS) is widely used for routine measurements of a longitudinal profile of electron and positron beams at BINP electron-positron colliders and other similar installations(1,2)'. LI-602 dissector is a part of many optical diagnostic systems and provides temporal resolution of about 20 ps. Recently a new generation of picosecond dissectors were created on the basis of the PIF-01/S1 picosecond streak-image tube designed and manufactured at the A.M.Prokhorov General Physics Institute (GPI) Photoelectronics Department(3,4). The results of the measurements of instrument function of the new dissector based on PIF-01/S1, which were carried out in the static mode(5), showed that temporal resolution of the dissector can be better than 3-4 ps (FWHM). The results of temporal resolution calibration of the new-generation picosecond dissector carried out at the specialized set-up based on a femtosecond Ti: sapphire laser and recent results of longitudinal beam profile measurements at BINP damping ring are given in this work.
