sPHENIX is a new detector at RHIC.

I agree with Jin's suggestions and congratulate you on a nice set of slides.

Hi Evgeny

 

That is a nice talk and hope you enjoy the conference. A few suggestions:

 

• Around the introduction, slide 2-7, good to show some actual pictures of sPHENIX. Here are mine, welcome to use https://photos.app.goo.gl/F9D87U9FyyNVvX8h9
• Slide 3: we can show the 2023 LRP now
• Slide 7+ : good to highlight the streaming capability of the TPC using this animation https://indico.bnl.gov/event/19839/contributions/77545/attachments/47941/81350/ClusterAnimation_pp.mp4
• Slide 9: should make it obvious that the right top plot is ALICE, not sPHENIX. And instead of showing all R1-3, suggest showing one of them and highlight our advantages and take away message on the plot
• Slide 12: good to mention this was the first full detector diffuse laser run (e.g. some of the hole is 1/6 diffuse laser head was not enabled due to testing)
• Slide 15 need some polishing as the cartoon on the slide is not easy to understand to an external person

 

 

Cheers

 

Jin

Subject: [Sphenix-l] TPC commisioning presentation draft for CPAD 2023

 

Dear all,
Attached is the first draft of the slides for CPAD Workshop 2023, SLAC, November 7-10.
Invenio link: invenio.sdcc.bnl.gov

 

sPHENIX TPC in the 2023 commissioning run
The sPHENIX experiment at RHIC was fully assembled and started its first commissioning run in the summer of 2023. This experiment will further investigate the microscopic nature of sQGP through precision measurements of jet, upsilon, and open heavy flavor probes over a broad pT range. The Time Projection Chamber (TPC) is one of the main tracking detectors in the sPHENIX detector. It is designed for operation in a 1.4 T magnetic field and high luminosity collisions to provide a rapidity coverage of |η|<1.1 and over the full azimuth.
Amplification in the TPC is provided by the quadruple-GEM stack. The signals are collected with zigzag patterned readout pads, and processed with the SAMPA ASIC. The stability of the GEM performance is controlled with the fast trip protection system. Two laser systems are tested and installed to calibrate the static and dynamic distortions.
In this talk, we will present the highlights of the first months of operation of sPHENIX TPC in the commissioning run.

 

If you have any comments, please let me know.
