PROPOSAL FOR A HIGH-BRIGHTNESS PULSED ELECTRON SOURCE

Proposal for a High-brightness Pulsed Electron Source*

We propose a novel scheme for a high-brightness pulsed electron source, which has the potential for many useful applications in electron microscopy, inverse photo-emission, low energy electron scattering experiments, and electron holography. The source makes use of Cs atoms in an atomic beam. Each cycle of the device begins with a laser pulse that excites a single Cs atom on average to a band o...

Proposal for research in high-brightness electron guns using high-field cathodes

High Brightness Electron Sources

The production of unprecedentedly high brightness electron beams is a critical aspect of many applications, from free-electron lasers to advanced accelerators. The preferred method for obtaining these beams is the radiofrequency photoinjector. The physics and technology aspects of this device are reviewed here, along prospects for future progress in high-brightness beam development.

High Current and High Brightness Electron Sources

The development of high current, high brightness electron guns is critically important for free-electron laser and energy recovery linear-accelerator light source facilities. In this paper, we will review the technical requirements of such projects and the status of on-going research throughout the community including results of emittance measurements and high current beam performance.

A Pulsed Electron Source for the HITRAP Cooler Trap

The HITRAP Cooler Trap will store highly charged ions and cool them to a temperature of 4 K for delivery to precision experiments [1]. The trap is preceded by a decelerator complex able to slow ion bunches delivered by the ESR from a specific kinetic energy of 4 MeV/u down to 6 keV/u [2]. The Cooler Trap is designed as a 23-ring cylindrical Penning trap, providing the ability to simultaneously ...
