Description
Technical field
The present invention relates to a kind of electron linear accelerators, accelerate more particularly, to a kind of electronic line of sight of quick obtaining vacuum
Device.
Background technique
The operation of medical computerized linear accelerator be unable to do without vacuum technique, needs the item in high vacuum, even ultrahigh vacuum
It is run under part.Vacuum technique mainly has in the effect of medical computerized linear accelerator:
(1) discharge breakdown in accelerating tube is avoided.
(2) gun cathode is prevented to be poisoned.
(3) collision loss of electronics and residual gas is reduced.
It will cause the consume of electron gun filament in medical electron linear Accelerating running use process, replacement electron gun filament needs
Destroy high vacuum environment.For high vacuum environment in long-time use process, a possibility that leakage, is big.It is after replacement gun filament and high
There is leakage and requires to rebuild vacuum in vacuum environment.Because entire cavity (accelerating tube) pipeline configuration be more than it is 3 meters long, only
The acquisition speed that one end has an external valve that can carry out vacuum to cavity is slow, and maintenance will expend nearly 24 hours and go to obtain phase every time
The vacuum level answered.
