Another thing I forgot to tell you, I got zap on this due to grounding problem and since then I stop playing on it. I did use PSpice simulation (dual SCR inverter) and it was good.
I'm getting some soon. But also I will have to finish building an inverter that I have just started gathering parts for. I'm planning to make my very own X-ray laser, so I figure I should build a power supply (in term of power conservation and safety) - for safety, it would have PIC24HJ flash microcontroller overseeing everything going on in the inverter.
So, if everything goes well, I would gladly post a link for you and the others to see.
True. Also, some digital camera with auto-focus may not like being near the X-ray tube - the CCD chips may still be able to see X-ray energy, thus throwing the microcontroller chip astray, thus messing focus up every times the X-ray tube fires.
Also, it's good that you have used phosphor (scinillator) sheet - safety-wise... I was wondering what kind of scinillator would be best and how cheap can they get? ( O_O Some aren't...)
OK. I got my green fluoroscopic screen from surplus. Anyway one time I was working with a Lorad mammography (24Kvp) and used a RM screen - cassette to check (green sensitive) for x-ray emission and what I got was a brown illumination instead of green and it was my first time to see this. Later on I found out the I had only 12Kvp instead of 24Kvp due to a control problem. Since then I could add that crystals do reacts differently below 22Kvp. Would you have any documents on this? If none!!
Still interesting. But if you still want to work with that, be careful not to get into its line-of-sight. If the unit's shielded behind thick Lead alloy, then it may be okay.
Still, remember that the more voltage the harder the X-ray emission get. If your inverter stuffs like, 100 Kilovolts AC into small X-ray tube, then 5-mm Lead shield would be useless. (Better to invest in 1 to 3 inches thick Lead alloy shield. Of course, I have worked with that before.)
I worked with different LINAC's (up to 25Mv) except for Electa and loves to tune waveguide and never use a stupid video camera when trouble shooting for loose connections or pcb but I personally goes inside the treatment room with beam-on (closed jaws. Of course nobody would like to come with me inside especially our medical physicist.
Thank you.....

Thank you much sir and good luck.

Thanks for the comment sir,
When I was a kid I had ADHD without knowing about it. Now I'm a full blown ADD and still have a hard time organizing my work area. What's your secret?
I play the piano to release some of my brain activities but the funny thing is I never had a formal school is reading notes.

you need to stop this! it's dangerous! all the radiation... i think it's very unhealthy. stop!

Thank you sir for your concern. This was done in the mid 90's and I stop doing it.
