An all-optical electron gun

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...

An All Optical Laser Wakefield Electron Injector

Designing an Integrated All-Optical Analog to Digital Converter

We present the procedure for designing a high speed and low power all-optical analog to digital converter (AO-ADC), by integrating InGaAsP semiconductor optical amplifier (SOA) with InP based photonic crystal (PhC) drop filters. The self-phase modulation in the SOA can shift the frequency of the Gaussian input pulse. The two output PhC based drop filters are designed to appropriately code the f...

Electron Gun Technology

Wisconsin Srf Electron Gun Commissioning*

The University of Wisconsin-Madison has completed installation of a superconducting electron gun. Its concept was optimized to be the source for a CW free electron laser facility with multiple megahertz repetition rate end stations. This VHF superconducting configuration holds the promise of the highest performance for CW injectors. Initial commissioning efforts show that the cavity can achieve...
