چکیده

This paper describes a pulsed electron gun that can be used as an FEL, as an injector for electron linear accelerators or for rf power generation. It comprises a 1 to 5 MeV, 1 to 2 ns pulsed power supply feeding a single diode, photoexcited acceleration gap. Beam quality of a ~ 1nC charge in ~ 1 GV/m field was studied. Computations of the beam parameters as a function of electrode configuration and peak electron current are presented together with descriptions of the power supply, laser and beam diagnostics systems.

PBPL Publications: 2009-00027 PUBLICATION ELECTRON EMISSION CHARACTERIZATION OF MG PHOTOCATHODE GROWN BY PULSED LASER DEPOSITION WITHIN AN S-BAND RF GUN

Pulsed laser deposition (PLD) has been proposed several years ago as a suitable technique to deposit a pure Mg film over a radio frequency (rf ) gun Cu backflange in order to obtain a high efficiency photocathode surface for the generation of high brightness electron beams. In this paper we report preliminary experimental results on the emission properties of a PLD grown Mg film within the high...

High Power Testing of a 17 GHz Photocathode RF Gun

We report experimental high power test results on a high gradient 17 G H z RF photocathode gun. The 1 2 cell, π -mode, copper cavity was tested with 5-10 MW , 100 ns, 17.145 G H z pulses from a 24 MW Haimson Research Corp. klystron. A maximum surface electric field of 250 MeV/m was achieved corresponding to an on-axis gradient of 150 MeV/m. The gradient was verified by a preliminary electron be...

Scheme for a coherently controlled pulsed electron gun

When the outer electron of an alkali atom in an electric field is laser excited just above the field-induced ionization threshold, the electron ejection will not be instantaneous. Calculations show there are a number of energy regions where, upon short-pulse laser excitation, the atom will eject a train of electron probability pulses with the pulses being nearly equally spaced in time. This sys...

Field Emission Dark Current of Technical Metallic Electrodes

In the framework of the Low Emittance Gun (LEG) project, high gradient acceleration of a low emittance electron beam will be necessary. In order to achieve this acceleration a-500 kV, 250 ns FWHM, pulse will be applied in between two electrodes. Those electrodes should sustain the pulsed field without arcing, must not outgass and must not emit electrons. Ion back bombardment, and dark current w...

Studies of Photo-emission and Field Emission in an Rf Photo-injector with a High Quantum Efficiency Photo-cathode

An 18 MeV electron photo-injector facility was constructed at Fermilab in collaboration with UCLA, INFNMilano, University of Rochester, and DESY. The photoinjector is now being operated in partnership with the Northern Illinois Center for Accelerator and Detector Development. The facility consists of an RF gun [1, 2] with a cesium telluride (Cs2Te) photo-cathode [3] excited by a pulsed ultra-vi...
