Preferred Label : gas-filled phototube;
IUPAC definition : Similar in construction to a vacuum phototube except that it is filled with a noble
gas (usually Ar) at a pressure of about 10 Pa. Photoelectrons accelerated by the anode
electric potential ionize gas atoms. The additional electrons provide a substantial
intrinsic gain.;
