    "abstract": "A new effect, gas amplification of electron energy is reported here; namely\nwhen a cylindrical pyroelectric crystal such as (LiNbO3) is contained in a\nconcentric cylindrical chamber and is heated and then allowed to cool in a\ndilute gas the maximum energy of the resultant focused electron beam more than\ndoubles as the pressure increases from 0.05 to 4 mTorr for seven different\ngases.",
