Hi Mark

Being similar the models, I accept gladly your offer.
Please get in touch by PM.

Thanks!

Hi Mark

Electronics inside the main box is splitted, as you can see in this picture.
I am not in the mood to track the wires, etc.

Hi Richard
Your approach is great, but I stick to the conservative way, not to modify too much the original object.

In my small collection, I have a Isoto, built in Argentina during the 70's. Copy of a French design.
Unfortunately I have no schematics to attempt to rebuild it.

Dan, I was talking of continuous EM.
My guess is that succesful intervent cleaned contaminated surfaces. May be partially but good enough to recover function.
Probably those that never recovered got chemical changes.
All in all, I recommend to give a try.

With regard to EM, my experience servicing mass spectrometers is as follows: Washing them with isopropyl alcohol (IPA) and drying it with clean, dry N2 usually permits to extend lifetime. Scrubbing with a cotton swab and extensive washing with IPA sometimes recovered a rebel one. Manufacturers preve...

Hi Jake

Beware not all BNC are hermetical.
We learned it the hard way...
See Andrew Seltzmann posts related to ion source construction.

What bothers me of this approach is the high vacuum required for a working mass quadrupole or ion trap.
Seems to be far away from the fusor typical operating pressures.

Right, good option.
Probably all we tend to start thinking from our own set up.
Surely I suggested the sputter version because I have a small 2.75” CF cross.

Hi Frank Of course you are right! The thread is related to the success of Japanese researchers who improved the neutron generation when using a chamber with titanium walls. See comments by Dan Knapp and Richard. Focusing on titanium, I suggested a cheaper way than a full titanium chamber, just depos...

Hi Rich

Thanks for the warning. I had forgotten the hygroscopic property of D2O.

There is a US thesis from the 60's about chromatographic separation of H2, HD and D2 with packed column and low temperature.
