Re: Progress Update

<t>Looks good, Great work.<br/> <br/> I would let the vacuum system run for a few hours and then see what your gauge reads. A leak is always possible, however in a brand new system contamination could be serious problem. If it keeps improving during a long pump down then that's the likely culprit.<b...

Re: MDP Controller?

Thanks Joe,

That's a lot more than I had to go on yesterday.
Based on that pin out this shouldn't be too hard.

Re: MDP Controller?

<t>The MDP 5010 has the same specs as the 5011, so I think it's essentially the same pump inside, just an older model. Biggest change I see is the field serviceability and extra cooling fins. The 5011 has an access port on the bottom for greasing the bearings.<br/> <br/> I believe the one I'm lookin...

MDP Controller?

<t>Someone's posted the info on a simple controller that should work for most Pfeiffer pumps, but I would like to have a stab at adapting it for another.<br/> <br/> Does anyone know the pinout for the Alcatel MDP 5010 / 5011 pumps? Someone in my area has a couple of these pumps just sitting around, ...

Re: Cheap Fluorinert

<t>FC40 has a lower viscosity and would be slightly easier to circulate through small tubing, but it's nothing that would keep you from using FC43 if necessary.<br/> <br/> One thing to keep in mind is that at high voltage there's really no such thing as completely non-conductive, regardless of what ...

Re: FICS Fusion...early stages

<t>May I recommend a UV Cure glass adhesive instead. <br/> <br/> There are various manufacturers, LocTite, Dymax, SuperGlue even makes one. You will likely find some at your local automotive store, though you might want to test the auto store version before use.<br/> <br/> Get everything lined up an...

Re: homemade neutron detector using ZnS(Ag) scintillator, is that possible ?

<t>According to the sources I've found, a 15cm thickness of plastic scintillator is between 20% and 30% efficient at detecting neutrons.<br/> <br/> You've got to get quite a but of scintillation material to really make it work well, however it can certainly be more efficient than attempting to adapt...

Re: Unknown source

<r>If it's anything like the ENI's that I have then it has a that the check source is most likely what they call a "Radium DEF" source. According to my research it's actually just a generic radium266 source with a number of radium daughters and various contaminants. Pretty much just a mix of radioac...

Re: PZT Transformer HV circuit diagram complete

<r>Curtis was attempting lead you to an answer that you probably already know; that if it has a frequency then it is by definition alternating in some form.<br/> <br/> Your circuit also has a DC Bias one way or the other depending on what you are measuring it against so depending on your setup they ...
