Abstract

The contribution of residual atmosphere gases to the flux of collectively accelerated protons in a Luce diode has been determined by comparing the number of protons generated by anodes made of polyethylene and pyrolytic boron nitride. Radioactivation diagnostics based on the nuclear reactions ¹⁰B(p, α)⁷Be and ¹²C(p, γ)¹³N has been used to determine the mean number of protons per pulse and their energy. It has been found that the number of protons accelerated collectively due to adsorption and ionization of water vapor and hydrocarbons from the residual atmosphere of the vacuum chamber on the surface of the dielectric anode insert may be comparable to the number of protons produced directly from the polyethylene dielectric anode insert.

残余气体对卢氏二极管中集体加速质子通量的贡献

摘要

通过比较由聚乙烯和热解氮化硼制成的阳极产生的质子数，可以确定残余气体对Luce二极管中集体加速的质子通量的贡献。基于核反应¹⁰ B（p，α）⁷ Be和¹² C（p，γ）^13的放射性激活诊断N已用于确定每个脉冲的质子平均数及其能量。已经发现，由于水蒸气和碳氢化合物从介电阳极插入物的表面上的真空室的残留气氛中吸附和电离而共同加速的质子的数量可以与直接由聚乙烯产生的质子的数量相当。介电阳极插件。
