Any update?

Hi,

Iv'e been too lazy to put it back together yet, I will be today though.

Glad to see it working again! Well done.

I decided to try the tube on my ZVS LOPTX circuit, check out the video below. I should imagine it's emitting X-RAYS in this configuration?

There's always some xray production when an electron is accelerated in a vacuum and then strikes a high density target, the question is how much xrays, and how much can exit the envelope. Based on the glass fluorescence pattern and the internal plasma pattern it looks like the tube pressure is too high to allow sufficient mean free path for sufficient electron acceleration needed to achieve substantial xray production. I.e. the electrons are hitting gas atoms and creating ions which are visible as the bluish cloud, and there's relatively little green fluorescence at the anode, both indicating a potentially low xray output. I wouldn't worry too much, but it's impossible to know for sure without radiological detection equipment.
