Studies of ion acceleration in a one meter laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1991)The basic concept behind the Laser Controlled Beamfront Experiment has been described in detail in previous reports(1,2) In the experiment, control over the propagation of a virtual cathode at the front of an intense ... -
High power RF amplifiers for accelerator applications: The Large orbit Gyrotron and the high current, space charge enhanced relativistic klystron
(1990-10-23)Los Alamos is investigating a number of high power microwave (RPM) sources for their potential to power advanced accelerators. Included in this investigation are the large orbit gyrotron amplifier• and oscillator (LOG) ... -
Collective ion acceleration via laser controlled ionization channel
(Institute of Electrical and Electronics Engineers, 1987)Initial results from a successful laser-controlled collective ion acceleration experiment at the University of Maryland are presented. In the experiment, positive ions are trapped in the potential well at the head of ... -
Experimental development of a millimeter wave free electron laser
(SPIE, 1990-12)A 1 MW (cw), millimeter wave FEL (X, « 0.5 mm) is currently under development with an application for heating fusion plasmas. Two salient features of the FEL are the use of a short-period wiggler £w < 10 mm) electromagnet and ... -
Demonstration of efficiency enhancement in a high-power backward-wave oscillator by plasma injection
(American Physical Society, 1989-05-15)An experimental demonstration of a strong enhancement of the interaction efficiency in a high-power relativistic backward-wave oscillator when plasma is injected is presented. Controlled plasma injection enhances the ... -
Relativistic backward wave oscillators: Theory and experiment
(IEEE, 1991)Microwave sources based on backward-wave oscillators with relativistic electron beams are capable of producing high power coherent radiation in the cm and mm wavelength regime. Although there have been a number of ... -
