Parallel coupled cavity structure with constant magnets focusing system

Accelerator for intensive electron beam (average current up to 2 A) from energy 50 keV up to energy 3-5 MeV is offered. Accelerating structure consist of a few resonators fed parallel from one waveguide. Focusing system contains constant radial magnets located between accelerating resonators and creating the axial alternating-gradient focusing magnetic field. Geometry and results of beam dynamics calculation such kind accelerator are presented

Status of a radio-frequency-based streak camera with sub-ps time resolution

We describe the status of our project for an RF-based streak camera. Measurements envisage the possibimity to operate within the subpicosecond domain. An evidence of a time resolution better then 0.6 ps has been demonstrated

Status of a radio-frequency-based streak camera with subpicosecond time resolution

Usage of a cavity with a high quality factor in a streak camera (SC) allows us to increase the energy of electrons up to 100 keV and therefore to reduce the influence of some of the effects that limit the SC time resolution. Time resolution up to 1.4 ps on a prototype of a radio-frequency-based SC (RFC) with circular scanning was demonstrated earlier. Following this, the new RFC was produced. The possibility of achieving a time resolution of 0.6 ps for a 350-ps single light signal is demonstrated. Preparation for experiments with spiral scanning (sub-ps time resolution for 10-ns process duration) is in progress
