[¦gas ‚am·plə·fə′kā·shən]
(nucleonics)
The ratio of the charge collected to the charge liberated by the initial ionizing event in a radiation-counter tube.

If the gas amplification can be as high as [10.sup.5] the threshold can be as low as 10 eV and then xenon is also good for detection of coherent scattering.
(1) Very high factor of the gas amplification (>[10.sup.4]).
But to get the gas amplification higher [10.sup.4] at High Voltage 3 kV the diameter of the cathode should be 40 mm, not more.
At higher voltages the counter acts like a ionization chamber with no secondary electrons occurring and the gas amplification is the same for all inc oming photons.
