Description
Bombarding the inner wall of the tube with thermal electrons emitted from a heated filament can reduce its secondary electron yield. However, after bombardment, exposure to air causes the secondary electron yield to increase rapidly. The variation of the secondary electron yield of fully scrubbed tubes under different storage conditions has been studied, with the aim of identifying an effective storage method to slow down the reversal of the electron bombardment effect.
