E-beam Triode for Multiple Submicrosecond
نویسندگان
چکیده
Externally controlled diffuse discharge switches offer the potential of submicrosecond opening time and high repetition rate. For the investigation of an electron-beam controlled diffuse discharge, an e-beam gun was constructed which allows submicrosecond, multiple pulse operation. The 200 kV, 100 cm2, e-beam with thermionic cathode is designed as a triode. The control grid is pulsed to generate several successive e-beam pulses of 100 ns duration and variable pulse-to-pulse interval. Electrical and optical diagnostics are used to monitor the triode performance. Preliminary switch experiments in N2-02 gas mixtures are discussed.

2.856-GHz MODULATION OF CONVENTIONAL TRIODE ELECTRON GUN
For the generation of picosecond (< 100 ps) electron beam pulses, we studied the RF modulation of a conventional triode electron gun. The feasibility study for this scheme has been experimentally investigated by modulating a triode gun of the Y-824 cathode-grid (KG) structure provided by the CPI Eimac, with 2.856-GHz pulsed RF’s generated by a solid-state amplifier (SSA). In this paper, we pres...
متن کاملMulti-slit triode ion optical system with ballistic beam focusing.
Multi-slit triode ion-optical systems with spherical electrodes are of interest for formation of intense focused neutral beams for plasma heating. At present, two versions of focusing multi-slit triode ion optical system are developed. The first ion optical system forms the proton beam with 15 keV energy, 140 A current, and 30 ms duration. The second ion optical system is intended for heating n...
متن کاملMarx Generator and Reflex Triode based High Power Pulsed Microwave Source
A compact repetitive Marx generator and a High Power Microwave (HPM) source based on a matched reflex triode has been developed and tested. The Marx generator rated at 1 kJ, 300 kV, 12 kA, 10 Hz, is suitable to drive the reflex triode directly. Bipolar charging of the Marx generator has been used to get lower system inductance and consequently faster output rise time with relatively low chargin...
متن کاملRealization of an all-optical triode and diode with a two-level-atom-loaded diffraction grating.
A finite-difference time-domain full-wave vector Maxwell equation solver is coupled with a two-level-atom model to simulate the scattering of an ultrafast pulsed Gaussian beam from a finite-length, metallic lamellar grating loaded with two-level atoms. The atomic medium is taken to be resonant at or near the frequency of the incident optical radiation. The highly resonant material and grating b...
متن کاملSteerable optical tweezers for ultracold atom studies.
We report on the implementation of an optical tweezer system for controlled transport of ultracold atoms along a narrow, static confinement channel. The tweezer system is based on high-efficiency acousto-optic deflectors and offers two-dimensional control over beam position. This opens up the possibility for tracking the transport channel when shuttling atomic clouds along it, forestalling atom...
