Ultra-Bright Pulsed Electron Beam With Low Longitudinal Emittance

View page
US Patent:
7755069, Jul 13, 2010
Filed:
May 16, 2007
Appl. No.:
11/749747
Inventors:
Max Zolotorev - Oakland CA, US
Assignee:
The Regents of the University of California - Oakland CA
International Classification:
G21G 1/12
G21K 5/02
US Classification:
2504931, 2504923, 250423 R
Abstract:
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 has been described. The source makes use of Cs atoms in an atomic beam. The source is cycled beginning with a laser pulse that excites a single Cs atom on average to a band of high-lying Rydberg nP states. The resulting valence electron Rydberg wave packet evolves in a nearly classical Kepler orbit. When the electron reaches apogee, an electric field pulse is applied that ionizes the atom and accelerates the electron away from its parent ion. The collection of electron wave packets thus generated in a series of cycles can occupy a phase volume near the quantum limit and it can possess very high brightness. Each wave packet can exhibit a considerable degree of coherence.

Active High-Power Rf Switch And Pulse Compression System

View page
US Patent:
57963142, Aug 18, 1998
Filed:
May 1, 1997
Appl. No.:
8/847058
Inventors:
Sami G. Tantawi - San Mateo CA
Ronald D. Ruth - Woodside CA
Max Zolotorev - Mountain View CA
Assignee:
Stanford University - Stanford CA
International Classification:
H01P 122
H01P 504
US Classification:
333 20
Abstract:
A high-power RF switching device employs a semiconductor wafer positioned in the third port of a three-port RF device. A controllable source of directed energy, such as a suitable laser or electron beam, is aimed at the semiconductor material. When the source is turned on, the energy incident on the wafer induces an electron-hole plasma layer on the wafer, changing the wafer's dielectric constant, turning the third port into a termination for incident RF signals, and. causing all incident RF signals to be reflected from the surface of the wafer. The propagation constant of RF signals through port 3, therefore, can be changed by controlling the beam. By making the RF coupling to the third port as small as necessary, one can reduce the peak electric field on the unexcited silicon surface for any level of input power from port 1, thereby reducing risk of damaging the wafer by RF with high peak power. The switch is useful to the construction of an improved pulse compression system to boost the peak power of microwave tubes driving linear accelerators. In this application, the high-power RF switch is placed at the coupling iris between the charging waveguide and the resonant storage line of a pulse compression system.

Ignition Feedback Regenerative Free Electron Laser (Fel) Amplifier

View page
US Patent:
62856901, Sep 4, 2001
Filed:
Jul 27, 1999
Appl. No.:
9/361675
Inventors:
Alexander Zholents - Walnut Creek CA
Max Zolotorev - Oakland CA
Assignee:
Bennett Optical Research, Inc. - Ridgecrest CA
International Classification:
H01S 300
US Classification:
372 2
Abstract:
An ignition feedback regenerative amplifier consists of an injector, a linear accelerator with energy recovery, and a high-gain free electron laser amplifier. A fraction of the free electron laser output is coupled to the input to operate the free electron laser in the regenerative mode. A mode filter in this loop prevents run away instability. Another fraction of the output, after suitable frequency up conversion, is used to drive the photocathode. An external laser is provided to start up both the amplifier and the injector, thus igniting the system.
