Abstract

A femtosecond x-ray streak camera based on photoelectron filter technology is reported in this paper. Photoelectrons are collimated through the slit and channel of the photoelectron filter, so that transit time spread and space charge effect of electrons are reduced. A planar-focusing high-voltage electron-optical system is designed to match the filter. The channel length of the filter is 300 μm, and the slit width is 20 μm. The streak tube using the photoelectron filter is 273 mm in length, and the extraction field value between the Au photocathode and the filter is 10 kV/mm. An experimental platform is set up to calibrate the streak camera, which is excited by a 266 nm, 130 fs UV laser. The experimental results show that temporal resolution is 357 fs and dynamic range is 182:1 of this developed camera.
