In cathode ray tube at 0.1 atm glow was produced but at pressure of 0.01 the original glow disappear why

dear student,
Discharge stops to pass through the gas, as no charge carriers are present in the discharge tube. As the pressure is reduced below 0.01 mm of Hg, it becomes difficult to maintain the discharge .so glow disaapears.
