TEMPERATURE LOG FOR X-RAY TUBES

摘要

An x-ray system 20 includes an x-ray tube insert 24 that has an evacuated envelope 34, an anode assembly 38 and a cathode assembly 40. The anode assembly 38 and the cathode assembly 40 are located in operative relationship to one another within the evacuated envelope 34. A temperature indicating member 100 is located in thermally conductive contact with at least one assembly 38,40, 66 located in the x-ray tube insert 24. The temperature indicating member 100 has a temperature sensitive characteristic which changes in response to adequate thermal exposure to at least one temperature threshold value.
