Hi all.
In facts the valve box should have included transportation blocks
for supporting the inside components including the current leads.
The blocks were removed at arrival at SLAC.

The current leads go through two small vessels (one per lead)
containing LHe and then move into into the vacuum vessel. This is a delicate coupling
vacuum sealed with stycast. It could be important these parts are well fixed
during transportation.

Now I am at home. Tomorrow morning I will look for some further information
about these blocks. In the meantime you can have a look inside the valve box
in a photo taken during the construction

Best regards
Pasquale

Wes,
I assume that your concern about the current leads means that you guys didn't
add any supports when you disassembled the magnet. If this is true then I
guess I'll have to scramble to come up with something before we can crate
the valve box for shipment. I modeled most of the valve box from the original
drawings, but I know that there is a bunch of stuff that doesn't show on the
drawings. If I have to design some supports I'll need some descent photos of
the bottom of the valve box if they are to have any chance of fitting. This
long-distance engineering sucks. Any information that you guys can provide
would be greatly appreciated. Thanks,

Paul Kovach

John,
I will attend your meeting this coming Wednesday. Just a few thoughts and
questions.

1) Will you be presenting shipping loads by truck as compared to the original
C5 delivery? If they are similar, I would suggest an analysis.

2) What about your thermal shield axial restraint. It looks better than, the foam
blocks that Mike Racine and I installed for moving the solenoid to End Station A.
However, the ends look "pointy". What is the impact of point loads on the
shield. I think you should do an analysis to verify that it is OK. Although the
shield is thin, it still has some substantial weight.

3) As I mentioned before, I am concerned about the valve control box,
particularly the heavy current leads.

Talk to you on Weds.

Wes

Pasquale, Wesley, and Mike,

I have attached some slides from Paul Kovach about the work they've done in
the Superconducting Magnet Division about shipping the BaBar solenoid to BNL
which we plan to review this Wednesday, July 30. Because you three have so
much experience and history with the solenoid, I would like your input on
whether the magnet is ready to ship here, and whether there are any
additional precautions we should take before we set a ship date. I would ask
you to plan to summarize your findings, comments, and recommendations either
collectively or individually in email(s) to me afterward so we could consider
whether we should take any additional precautions.

BNL is now paying for BlueJeans videoconferencing, which you should be able
to connect to without any special hardware or software (although you will
need a decent network connection). If there are problems with the
connection, call or message me on skype (johnstonyb) and we'll move to that.
The meeting is

11am EDT
8am PDT
5pm CEST

and I have the start a little bit earlier in case of connection problems; I
think the meeting will be about an hour or perhaps a little more.

John,
July 30th at 17:00 is fine with me.
I suppose we will use skype.

Best regards

Pasquale,

I think I've touched base with everyone who should hear about this;
Mike Anerella unfortunately is out the week of July 28, but Paul
Kovach can do the presentation.

Paul, if you can put some slides together by next Friday, July 25,
that will let them think about it in advance.

I suggest we try for sometime on Wednesday, July 30, and if something
comes up, we can shift a day later.

The time... difficult to accomodate all nine time zones; the best I
can see would be 8am at SLAC, 11am at BNL, and 5pm in Italy. Would
that work?

In the other two weeks I will be in vacation.
However if you have material (slides, reports, ..), which can be
circulated I can read and comment in any case.

Best regards

Pasquale

Pasquale, Wesley, and Mike,

I hope you're having a good summer--I'd like to see if we can
interrupt it for a couple of hours for you to look at what my
colleagues in the Magnet Division and I are envisioning for
shipping the BaBar solenoid to Brookhaven. We are hoping we can
complete our arrangements in this fiscal year (i.e., to ship at
least the solenoid itself before October 1), and I think we're on
track for that, but I think we should take a step back and discuss
our plans to make sure they make sense to you. A recent science
review of the project was quite positive, and we think we can
proceed with the next steps in shipping and testing the magnet.

Of course, finding a time in mid-summer to do that is always
problematical. We may have to resort to a doodle poll, but as a
start, is there any time in the weeks of July 28, August 4, or
August
11 that you could reserve around 2 hours for an engineering
evaluation of our plans?

Thanks very much in advance for your past, and hopefully future,
willingness to help us with this.
