My mistake. I didn't see the laminations on the core. That small of a laminated core would be a very small duty cycle. My old eyes on a small phone display fooled me.

I was at the dentist yesterday for annual X-rays and noted that the machine was 65 KV 8 mA and the exposure time was 0.08 seconds! My office uses a digital sensor, the "teeth pictures" show up right away on a flat screen monitor.

If you could figure out how to liquid cool that transformer at a high flow rate it might work for a fusor, it would also depend on how fine the wire is in the HV winding.

We have a real time x ray microscope at work. 20uA is plenty for giving contrast in non-metallic objects easy, if not overexposed. I guess a head-sized object would need more like 50uA (not that the safety systems allow you to stick your head in it!! :) ). The max 200uA setting is for getting good contrast when penetrating mm worth of metal.
