sPHENIX discussion of the superconducting solenoid

["Yip, Kin" <kinyip AT bnl.gov>]

Hi,

 

Thanks !   If you’re not clear about what we (esp. Carl) want, please don’t hesitate to ask (though I

believe you guys know very well).

Hi Kin

                  Piyush is not here this week so things are kind of crazy, I will speak with Joe and see if we can come up with a time.

                                                                                                   My thinking is towards the middle of next week.

Hi Sonny,

 

I hope you can find time to help us with the voltage tap stuff in the doghouse, among your busy schedule.

Hi

 

   Kin, they sent me an email and Joe is busy right now. He may get to it

next week.

Dear Sonny and Joe,

I just went to check and from my limited understanding and observation, it seems to me that you guys have not started trying to find VT11 and
make new spares and reroute (like what Carl has written in his email on Apr. 17).

What's your plan of doing these things ?   Can you please kindly share with us ?

Hi,

I went there at ~10:20 am and everybody has gone.  I understood that Carl talked with Ray this morning.
Carl and I went there again later and we examined it a little.  Apparently,  Ray has opened much more than
before.   I hope Joe can find VT11 (though we can't be too sure where it's) and add additional ones.

Hi Joe,

 

   I talked to Ray this morning and he said you might

be able to work on the voltage taps later today.

 

I just want to remind you to check VT11 before too much

is taken apart.

 

As a reminder:

1. We want to put in redundant voltage taps for VT11 and VT05.
2. We want to reroute VT05 through VT11 (7 voltage taps) to

the connector on the bottom of the new doghouse.

 

Please let me know when you think you will be able

to get to this.

 

Thanks
