OK
I whet the whistle with what i was doing on the water cooler
but it has dissappeared
The following pics are of the modified system that can go to 100kV+ with plenty of mA
x-rays are a real hazard with measured values in the many
100s of mSv/hr
A radiation wall of concrete filled cinder blocks has been constructed. Interesting to note the wall works very well but turning the detector with its sensitive face upwards gives us around 150uSv/hr being reflected (backscatter) off the roof. The new spellman supply STR series 150kV @ 40mA is remote controllable, although the supplied software is extremely clunky with a mind of its own. So we will set up and enable the supply then make ourselves scarce while we wind up the voltage remotely over the ethernet connection to the supply. Only 1 high voltage breakover outside the tank so far and alot of work to clean up the charring of the big plastic insulator.
We have a camera inside the terminal area that is repeated on the 19" monitor at the control console so we can check on arcs etc
pics are of the system into the view port @ 33kV and then 90kV note the plastic is trying to track internally
The vertical stack of resistors in the centre of the outside pic is the ballast resistors 150k ohms
enjoy
