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!
