一个有趣的效果，“气体放大的电子能量”在这里报告，即当一个圆柱形的热释电晶体，如（铌酸锂）是包含在一个同心的圆柱形腔室，并被加热，然后允许在稀释气体中冷却，所得的聚焦电子束的最大能量增加一倍以上的压力从0.05到4毫托为七种不同的气体。
An interesting effect, “gas amplification of electron energy” is reported here; namely when a cylindrical pyroelectric crystal such as (LiNbO3) is contained in a concentric cylindrical chamber and is heated and then allowed to cool in a dilute gas the maximum energy of the resultant focused electron beam more than doubles as the pressure increases from 0.05 to 4 mTorr for seven different gases.
