Bringing an x-ray tube up to optimum operating parameters should be 
done after replacing a tube or if one has been idle for more than a month 
or so. Start at minimum kv and ma , then raise kv 4 or 5 kv and ma 2 ma 
at a time every 30 minutes until maximum power is reached. If you hear 
arcing or if the ma is not stable turn power down and start again. Make
tube cooling is adequate!     Good luck,     Joe Ayers
