A new 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.Comment: 5 pages, 5 figures, pd
