8.4.1 Parts Required for Periodic Replacement
Here are parts required for periodic replacement
8.4.2 Replacement of magnetron
When mounting a new magnetron, do not touch the magnet with a screwdriver or
put it on an iron plate. After replacement, connect the lead wire correctly.
Handling of Magnetron under Long-Time Storage
The magnetron that has been kept in storage for a long time may cause sparks and
operate unstably when its operation is started. Perform the aging in the following
procedures:
1) Warm up the cathode for a longer time than usually. (20 to 30 minutes
in the STBY state.)
2) Start the operation from the short pulse range and shift it gradually to
the longer pulse ranges. If the operation becomes unstable such as
the magnetron current is unstable, in during this process, return it to
the standby mode immediately. Keep the state for 5 to 10 minutes until
the operation is restarted.
