[Sneap] Pd-leak problems

[Chris Westerfeldt]

HVEC used to sell replacement Palladium thimbles and we have replaced them
in the distant past.  I do not know if HVEE can still supply these or not. I
understood that they no longer manufactured these leaks - but I may be
wrong.  My experience is that when these leaks cold-flow, it is usually due
to a crack in the thimble from thermal cycling or over heating. We have
resorted to using the thermo-mechanical leaks in their place as we could not
repair them any longer.  Potentials used to manufacture their own version of
the Palladium leak - you may wish to contact them (

Regards,
