The military, who used the most 5062C, Actually had an maintenance note
about increasing the Cesium oven temperature to get the last bit of life
out of the tube.

On the 5061A/B tubes the STD tube runs at 85C and the high perf. at 115
to 132 C (marked on tube label) You can measure the temp by clipping a
thermocouple meter to the two exposed leads poking out of the RTV. select
a new oven set resistor to increase the temp by 20 degrees and see what
you get.

About heating the entire tube, mght not be a good idea as all the stuff
in the gettering would get released and you might not be able to pump
down to vacuum again! Also too hot and the magnets might weaken!
