Micro gas-puff based source

DWPI Title: Micro fluid-puff based source for generating plasma, has pulsed power source that is coupled to anode and cathode for applying voltage across the anode and cathode
Abstract: Various technologies described herein pertain to a micro gas-puff based source of neutrons, x-rays, and/or energetic particles. The micro gas-puff based source can generate plasma, which can emit neutrons, x-rays, and the like. The micro gas-puff based source includes a diode, which further includes an anode and a cathode. Further, a chamber is between the anode and the cathode. Moreover, a MEMS gas supply can inject a puff of gas between the anode and the cathode within the chamber, where the MEMS gas supply shapes the puff of gas to form a quasispherical density profile of gas created in various of geometries. Further, a pulsed power supply applies a voltage across the anode and the cathode to cause compression of the puff of gas to form the plasma.
Use: Micro fluid-puff based source for generating plasma.
Advantage: The micro fluid-puff based source can provide increased production efficiency of neutrons. Hence, time-of-flight measurements can be enhanced due to narrow pulse widths, and the micro fluid-puff based source can be robust and long-lived.
Novelty: The micro fluid-puff based source (100) has micro-scale fluid supply (110,112) that injects a puff of fluid between an anode (104) and a cathode (106) within a chamber (108). The micro-scale fluid supply shapes the puff of fluid to form a quasispherical density profile that is non-uniform between the anode and the cathode. A pulsed power source (114) is coupled to the anode and the cathode for applying voltage across the anode and the cathode to cause compression of the puff of fluid to form plasma. The plasma formed by fluid-puff based source emits neutron, x-ray and energetic particle.
