At 4000 volts, the magnetron is going to draw at least a hunderd ma.  The
only way to limit magnetron current to less than a milliamp is to lower the
voltage a lot.  Unfortunately, this causes the magnetron to stop oscillating
and become a vacuum tube diode - useless for your experiment.

Be careful with a magnetron that is oscillating - you can do a lot of
microwave RF damage to yourself.  Eyes are especially sensitive.  There is
good reason for the interlocks on microwave oven doors.
