sPHENIX MAPS tracker discussion

Dear sPHENIX MVTX Team,

 

I would like to submit an abstract to DNP 2023 for an oral presentation. Below are the title and the abstract:

 

 

Title: sPHENIX MVTX Commissioning at BNL

 

Abstract: sPHENIX is a new state-of-the-art heavy-ion physics experiment at RHIC in the past 20 years. At the center of the sPHENIX detector, the Monolithic-Active-Pixel-Sensor (MAPS) based VerTeX detector (MVTX) is a high-precision silicon pixel detector adapted from the ALICE Inner Tracking System. The MVTX provides excellent position resolution and the capability of operating in continuous streaming readout mode, allowing precise vertex determination, and recording a large data sample, both of which are particularly crucial for heavy flavor physics measurements. The MVTX has been installed to the sPHENIX detector on April 1. sPHENIX has completed its first year Au + Au collision data taking from June 18 to August 1. During the run, a significant background, potentially due to beam halo, is observed by the MVTX. ALICE also reported similar issues at the LHC in Run 2023. Cosmic data have also been taken for calibration and alignment purposes. In this talk, we will present the commissioning and the performance of MVTX detector. Studies on MVTX raw data processing, beam background, noise level, and tracking alignment will also be discussed.

 

 

If you have any comment or suggestions, feel free to email me. The deadline is by 5pm on Sunday October 22. Thank you very much!

 

Sincerely,
