High voltage dc gun for high intensity polarized electron source

open access: yesPhysical Review Accelerators and Beams, 2022
The high intensity polarized electron source is a critical component for future nuclear physics facilities. The electron-ion collider requires a polarized electron gun with higher voltage and higher bunch charge compared to any existing polarized ...

Nanotip electron gun for the scanning electron microscope [PDF]

open access: yesScanning, 2005
Experimental nanotips have shown significant improvement in the resolution performance of a cold field emission scanning electron microscope (SEM). Nanotip electron sources are very sharp electron emitter tips used as a replacement for the conventional tungsten field emission (FE) electron sources.

Suppression of parasitic secondary emission in a magnetron-injection gun of a 24-GHz technological gyrotron

open access: yesResults in Physics, 2021
This article analyzes the ways of reducing the parasitic emission current in the electron beam formation system of a technological gyrotron. The operation of the magnetron-injection gun in the quasi-critical mode and the profiling of the cathode can ...

The ALS Gun Electronics system [PDF]

open access: yesProceedings of International Conference on Particle Accelerators, 2002
The ALS Gun Electronics system has been designed to accommodate the gun with a custom made socket and a high speed electronics circuit which is capable of producing single and multiple electron bunches with time-jitters measured at better than 50 ps. The system generates the gated RF signal at ground level before sending it up to the 120 kV-biased gun ...

An all-optical electron gun [PDF]

open access: yesScience, 2017
Optics Short bunches of electrons are used extensively to yield information about the structure of materials and the dynamics of phase transitions. Traditionally associated, perhaps, with “big science,” the availability of accelerator beam time and the timing resolution of the pulses can be limiting factors for experimental studies. Huang et al.
