ebay crate - scint detector
Posted: Fri Aug 19, 2011 10:19 am
I was idling on ebay a few days ago and grabbed something one of my 'regular' ebay vendors was selling;
Not tried it yet, I'm told it appeared to work OK on a 400V GM tube.
I bought it mainly because of a post by Alex Klotz on fusor; http://www.fusor.net/board/view.php?bn= ... 1308449638
He says he plugged his CNM 18-1 tube into an Ortec and seemed to have no problem running it.
However, I am not familar with this kind of gear and would like to ask what sort of 'tube load' this is expecting to see. I mean, the corona discharge tubes run with a few 10's uA running through them. What is on the front end of that 'HV' port, is there a resistor and a signal is taken off the port-side of that resistor, does that mean I should add a resistor-and-cap in series to the corona tube? The kit looks good and the vendor has been reliable before, so my only worry now is that I don't blow it up somehow through my ignorance. (Which included never seeing this plug type before - PET 100 - never heard of it before a few days ago).
So, what means of connection d'y'all think I should make between 18-1 and this to get the best out of the tube? (Esp @ Doug, as you've worked with these corona tubes now)
