sPHENIX discussion of the superconducting solenoid

["Danielson, Nils S" <ndanielson AT bnl.gov>]

I spoke to the guys working out at 1008B. For what it is worth the locations they really need to end up at is not the information I was given when I asked for it.

They will be moved sometime today.

Tom, Nils;

 

 

Can you please call the CAS Tech Shop and talk to Joe DeCicco He can meet you out by the PS and show you the place where the cables should go.

Hello Tom,

 

Can you please help point to Pablo where those signals come from in 1008 B ?

Hi,

 

You are talking about just current signal ? (Or also the cryo permissive ?

 

Cryo group did all that ... We should contact Nils Danielson,  L. Masi ...

Good morning Kin;

 

 

 

I took a looked at the cable’s, I would prefer not to splice them to extend them. If you can show me where they are coming from I will run new cables to the PS and the DCCT Half Rack.

 

 

Thanks

 

 

Pablo

Hi,

 

Thanks Karl for making those copper bars which will be used to connect the Current Leaks with the 2*12  535-MCM cables.

 

In the picture which I took this morning, it shows that Lenny Masi holding 3 cables.  The thickest one is for those TT01…5 thermal sensors (strain gauge) and linear-pot, the 2^nd thickest one is one with 8 conductors for 2 cryo-signals  (Cryo-permissive …) and the thinnest one is for the magnetic current.      These cables are only long enough for Carl’s DAQ rack.   To connect them to the PLC of the Magnet or even the DCCT rack (also on the mezzanine), you have to “extend” them yourselves.

Hi Kin,

 

The Buss Bars were purchased and fabricated to your specifications.

 

Thanks,

Rob

Hi Rob,

Have you purchased and even fabricated the copper bars for dealing with 12*2 (=24) 535 MCM (locomotive) cables ?

And, have you also found or purchased 535 MCM cables (24) to connect them from the West Wall of 1008-IR to the Valvebox on the platform ?

I just was chatting with Dennis Donaldson ... Dennis has started to think about the cable tray for these MCM cables.
In the very rare occassion that we would want to move the entire sPHENIX carriage out of IR into the Assembly Hall, it'd be probably some work to move those MCM (locomotive) cables to somewhere. 

And I just talked with John Haggerty (senior physicist in sPHENIX), he's re-convinced me again that though nothing is impossible, we (sPHENIX) won't move the carriage from IR to the Assembly Hall.  Because for that "movement" (IR->Assembly Hall), they have to break the beampipe, take out all those detectors MVTX/IINT (spelling?) etc. etc. which are very painful to install and take out.  Not to mention these MCM cables.

Hi Kin,

I will take care of fabrication of copper buss bars for SPHENIX.

Hello Rob,

 

Can you please confirm that you got the following messages about making the copper bars below ?

And you’ll find time to purchase and drill 12 holes for these two copper bars, please ??

Hi,

 

I forgot to say that you may use budget code 16719 for purchasing copper as well as the labor.

 

If anyone in your group wants to charge 16719 for labor but has never done so in the past, please let me know of their name so that we can approve him/her to charge 16719.

 

Kin

Subject: copper busses need to be made

 

Hi Rob and David,

I'm afraid that we have to make those two 12-hole copper bars again.  I asked around and visited 1008, 1005, 912 ( a few times) and talked/emailed to ~several people (Pablo, PK, Dennis, P. Orfin, T. Tallerico,
F. Toldo, R. Ceruti, ... Paul/J. Benante haven't replied yet).  Nobody seemed to know their whereabout.

So, can you please help make them ?   I attach a picture of with the copper busses with a tape measurement.   It looks like that the longest dimension is about 11" but really you can measure the dimension of each lug
and we need to put 6 of them on one side => at least you need to have 6*width(lug).   It should be about 11 inch from the picture.   ( The total of cables is 12 this time, compared to 8 last time. )

For the smaller sides, I suggest 1.25" x 4" if possible, which would give a cross-sectional area of 5 square inch.   Carl Schultheiss and Pablo Rosas both said that 1000 A needs 1 sq. inch of surface area and
since we are 4600 A or almost 5000 A, we need 5 sq. inches 😊   1.25 x 4 = 5  OR (1+2/3)" x 3" is OK etc. etc..
