High power transmission devices
components
-
WR1500 or WR1800 waveguides: for RF power transmisson
-
circulator: for protection of the klystron from reflected power
-
magin-T: devide the RF power into two
-
dummy loads: absorb the reflected RF power. Pure water load is used.
-
phase shifter: for adjustment of the path length
-
E-bend, H-bend, bellows:
rectangular waveguide
