Hi,
Henry Hocker just gave me the completed Traveler which contains the
results of the Inspection/Acceptance tests.
I put it here :
https://collab.external.bnl.gov/sites/sPHENIX-Magnet/Shared%20Documents/Inspection%20and%20Acceptance%20Test/Acceptance-Inspection%20Traveler%20(Completed).pdf
{ which is
https://collab.external.bnl.gov/sites/sPHENIX-Magnet/SitePages/Home.aspx
=> "Shared Documents" => "Inspection and Acceptance Test" }
if you want to take a look.

Dear Henry,
Ray Ceruti told me that he's returned the Traveler to you.
There are some useful results on the Traveler. And in any
case, in our sPHENX
Magnety meeting yesterday, various participants requested to
have a copy. Could you please send me a copy (electronically
scanned or just
paper) of the Traveler so that I may distribute ?

Good
Morning Kin,
Yes, we did the Leak check as per the Traveler. Those
travelers incidentally were returned to Henry Hocker when
we picked up the area. The Work Control Permits (green
sheets) were set to Peter Cirnigliaro.
Regards,
Ray

Hi Ray,
Thanks for the clarification !!! So it seems to me that you
did do the "leak check" as specified in the "Traveler".
By the way, I couldn't find any folders any more by the
sPHENIX magnet. Did you take them all and/or return to
Peter Cirnigliaro or ??

Hi
Kin,
We used a mass spectrometer to perform a leak check on
the two internal helium cooling circuits within the
vacuum vessel. The mass spectrometer showed there was
no leak with the two internal systems held under 81 psig
helium pressure for ten minutes each. The internal
systems passed a leak check (at room temperature) with
no problem, we did not leak check the outside vacuum
vessel for external atmospheric leaks however as it
pumped down very well as it was.

Ray

Dear Mike
and Roberto,
Ray Ceruti told me the following in the email below. What
he said seems to make sense.
The "traveler" said something about using "mass
spectrometer" to do leak check ... Do you guys think it's
still necessary to do this ?
If you guys think that it's not necessary, then it's fine
with me. ( It's also possible that I don't get a
complete picture from Ray ... )
Can
you please advise ??

Hi

We didn’t perform a leak check on the vacuum vessel.
It pumped down very well and since this unit has been
in service before, we didn’t believe it was necessary.

Dear
Ray,
> The pressure test went according to plan and
was a complete success.
In the meeting when I reported "your complete success",
people wonder
whether you've also done the "leak check". Can you
please confirm/let us know ??
In our meeting today, I've checked with P. Joshi/R.
Lambiase et. al., they told me that they don't need any
vacuum to do their ramp test /
measure inductance etc. You may shut off the vacuum
whenever you see fit.

Hi Ray,
I believe you've finished your pressure test. Can you
please let me know of the outcome ??
