Greeting all. First post.
Got a problem with an old Kolrad K2 Yag 3/4 beam laser system at work that I try to keep alive. The problem is with the EG&G KN2 Krytron tube (http://en.wikipedia.org/wiki/Krytron). The tube is used to trigger the high voltage for the 20K pulse for the large flashlamp. After a time the tube wears out and will not wait for the trigger signal to fire but will instead fire at random charge levels. Not good. Perkin Elmer purchased the EG&G division that produced the tube then shut down the plant about ten years ago. These tubes appear to be impossible to find now so I was looking at any way to create an electronic version of a KN2 tube. Any suggestions ?
Thanks,
Tom
