Title: Development of a High Flux Source of Gas Phase Carbon and/or Boron Atoms
Agency / Branch: DOD / USAF
Contract: N/A
Award Amount: $79,983.00


The energy required to convert solid carbon or boron into gas phase atoms becomes stored energy if these gas phase atoms are trapped without reaction in a solid hydrogen matrix. This energy is released when the carbon-hydrogen fuel mixture is burned in a rocket engine increasing the specific impulse of the fuel. The task of producing high energy density fueld is frustrated by the lack of a high flux source of gas phase carbon atoms having adequate purity (99%) that is both compatible with cryogenic trapping requirements and is economical for commercial applications. Thermal evaporation or laser ablation sources do not meet these cryogenic and economic requirements, respectively. HY-Tech proposes to build a plasma discharge source utilizing a metal vapor vacuum arc (MEVVA) to generate a pure carbon plasma that is confined and guided to a biased electrode where the ions are recombined through an Auger tunneling process. Incorporating an electrode avoids the cryogenic problems that would arise if a conventional neutralizing gas cell was used. The mass of carbon atoms per unit of charge transfer in the arc will be determined for designing the Phase II system. Estimates indicate that the required flux of 0.21 g/hr can be generated at an average power consumption of 0.8 to 1 kw of electrical energy.
