Dear Zhenyu,

I do not think people will go back to your overview talk to find the action items, this is why I listed them again

Dear Elke,

Thanks for the notes. My email did not contain any action items which were already in my overview talk https://drupal.star.bnl.gov/STAR/system/files/yezhenyu_STAR_20190808_v1.pdf

Dear Zhenyu,

I have quite some additional action items, which need to be done till the end of September

• Need to get an detailed assessment of the cooling system

Slide 14

• Do we want to test a sensor in the experiment in 2020
• if yes what are

in my email below “integration: Rahul will think of what are required and how to install a FST module into STAR during the 2020 run"

• Cooling system: initial evaluation and MIT engineer to come and do service.
• we have all manifolds, but what other parts are missing

In my email below "Integration - Rahul will produce an integration proposal to include the service components (cables and cooling tubes) by the end of this month.”

• What is our plan o survey the modules to the rest of STAR

This one I omitted.

• Do the current cables and the cooling lines fit in the current space, if not can we use less expensive more flexible cables
• Deadline end of August

In my email below "Integration - Rahul will produce an integration proposal to include the service components (cables and cooling tubes) by the end of this month."

• We need tracking studies to see if we still can optimize the r-phi segmentation

For the tracking studies, I requested the following information from Daniel during the discussion on Friday. I hope it is clear.

1. describe and present the performance in details how the track (hits) finding is done in p+p with his new tracking code
2. present the performance (to see how bad it is) in details how the track (hits) finding is done in Au+Au with his new tracking code
3. See if doing any shifting, rotating of Silicon disks, or more r-phi segmentation can help the tracking performance

Best,
Zhenyu

Cheers elke

There will be a change in the funding strategy, namely, the funds for production Silicon sensor purchase will be provided through BNL/DOE. Flemming will join the project as a deputy manager to oversee the financial and scheduling, and a local BNL contact for cooling system and integration.

Some action items:
Integration - Rahul will produce an integration proposal to include the service components (cables and cooling tubes) by the end of this month. Rahul will think of what are required and how to install a FST module into STAR during the 2020 run.

Mechanical structure - Yi will look into the outgassing, radiation hardness and radiation length of the glue that is proposed to mount the hybrids onto the mechanical structures, and those of the soft tubes for cooling.
