Hi Anthony,

Thanks for the feedback! I have attached an updated version.

Best regards,

Hi Shuhang, 

Thanks for sending this to the list! 

One general comment is that you're at 119/350 words, so not even half the overall word count limit. Similarly to a comment I gave Emma, I think it's totally okay to show off the fact that the HCal's (at mid rapidity) are really new to the RHIC scene, especially as a focal point of a jet physics program. 

"Critical to full jet reconstruction is the sPHENIX calorimeter system, which needs to be properly calibrated prior to and during the data taking to measure the energy deposition of jets."

I would expand this sentence to include such a statement and maybe some more information on the HCals (such as their material composition). 

"the possibility of calibrating the hadronic calorimeters (HCals) to the Minimum Ionizing Particle (MIP) scale using cosmic muon events when the full sPHENIX apparatus is in its data-taking position"

I think you might be able to remove "when the full sPHENIX apparatus is in its data-taking position". I think this is meant to contrast against cosmic testing when the HCal sectors are in test benches right? I think that's somewhat internal knowledge, so your average QM goer won't understand that. 

Alternatively, I think with the space you have, you might mention previous cosmic testing that's been done, and then conclude with "but now we want to do cosmic testing with the full assembled detector, and this simulation will help determine how we do that (with regards to say, a triggering system?)".

Best,

Subject: [Sphenix-calibration-l] HCal cosmic MIP scale calibration poster abstract

 

Hi all,

Here is my poster abstract for HCal cosmic simulation and calibration. Any comments and suggestions would be appreciated.

Title: Cosmic Muon Simulations and Absolute MIP Calibration for the sPHENIX Hadronic Calorimeters

The sPHENIX detector at BNL’s Relativistic Heavy Ion Collider (RHIC) will start data taking in 2023 and seeks to understand the microscopic properties of the Quark-Gluon Plasma(QGP), by performing high precision measurements of jets and heavy flavor observables. Critical to full jet reconstruction is the sPHENIX calorimeter system, which needs to be properly calibrated prior to and during the data taking to measure the energy deposition of jets.This poster will discuss a GEANT4-based study that utilizes a cosmic muon generator with a realistic zenith angle and energy distribution to explore the possibility of calibrating the hadronic calorimeters (HCals) to the Minimum Ionizing Particle (MIP) scale using cosmic muon events when the full sPHENIX apparatus is in its data-taking position.

Thanks,

Shuhang
