An R.F. Modulated Electron Gun for Nina Injection Equipment

Progress toward an All Niobium Superconducting Rf Photocathode Electron Gun*

Advanced Energy Systems Inc (AES) and Brookhaven National Laboratory (BNL) are currently working on a program to develop a Superconducting Photocathode Electron Gun using an all Nb cavity. The work is being performed as a Phase II SBIR and under a CRADA between AES and BNL. Results of initial efforts have been presented previously [1,2]. This paper will review the progress being made in this pr...

Development of a Novel Superconducting Rf Photocathode Electron Gun

Over the past year Advanced Energy Systems Inc. and Brookhaven National Laboratory have undertaken a program to develop a Superconducting Photocathode Electron Gun utilizing a unique cathode concept. The cathode concept is much simpler than many other approaches and should avoid many complications which might otherwise be encountered. This cathode concept does not utilize an insert of any kind ...

Femto-seconds Electron Beam Diffraction Using a Photocathode Rf Gun*

One of the 21 century scientific frontiers is to explore the molecule structure transition on the femtosecond time scale. X-ray free electron laser (XFEL) is one of the tools now under development for investigating femto-second structure transition. We are proposing an alternative technique – femto-second electron diffraction based on a photocathode RF gun. We will present a design of a kHz fem...

Femtosecond Electron Bunch Generation Using Photocathode Rf Gun

A femtosecond electron bunch is essential for the observation of ultrafast phenomena. In order to improve the time resolution of pulse radiolysis and ultrafast electron diffraction (UED), that involve the use of an ultrashort electron bunch and ultrashort light, a femtosecond photocathode RF gun was investigated experimentally. The bunch length due to space-charge and RF effects in the gun was ...
