All,

 

As discussed last meeting, I’ve compiled the documentation and posted it to the wiki: https://wiki.bnl.gov/star/index.php/Cables

 

T-Board/Inner Signal Cable:

 

Last meeting we agreed we would use the IST-type of cables, due to cost. It turns out I misinterpreted the quote – we were quoted for 400ft of cable but they had a minimum 1,000ft order. It is cheaper as Gerard expected to use the Polypropylene/PVC/PVC cable. I’m waiting to hear back from Gerard on how he’d like to proceed. The updated quotes binder mentioned can be found here: https://drupal.star.bnl.gov/STAR/system/files/Cable%20Quotes%20Binder%2010-28-2019.pdf The quotes binder also includes new updated (non-expired) quotes, so once we have a decision we can order the cables. (Elke/Gerard/Zhenyu, will this be on one of the BNL accounts, or will I be sending this to someone else? If it will be on a BNL account I can start drafting the PO so it will be ready to send when we make a final decision).

 

 

 

Regarding the V2.1 T-Board modifications, I believe we just need to remove a handful of parts to in order to make it work, I’ve discussed this in an email with Jianing and Gerard, and am waiting to hear back from Gerard. I will have the cables re-labeled tonight before I leave (to match the VIA REF DES used in V2.1 T-Boards we are assembling). Once Gerard gives me the O.K. I’ll pull the parts off the boards, and we should be able to give them to the assembler within a working day or two. If there are no objections, I will extend the due date for the vendor to November 29.

 

If I’ve missed any points please let me know.

 

Best,

     Mike Capotosto

Dear all,

I am very sorry for missing the meeting. Obviously I should not have called for a remote meeting in the evening of the banquet of a workshop at a different time zone. Please accept my apology and kindly email your status reports to the list.

3 Module Assembly at Fermilab - Zhenyu Ye
Fermilab technicians did the wire-bond test with the .58mm shift and did not have any problem during the first bonding (see the pictures from the link below). They indicated if we were to do second bonding that there could be a difficulty, i.e. remove some bonds and redo them. I don’t expect we need to do second bonding to the front-end pads (we did not do this for IST), therefore I told them that for the prototypes we will stay with the current positions, and can change for the production if we would find it is needed from prototype assembly. They are ok with this.
