Dear Colleagues

Here's a work in progress version of the detailed nHCal geometry implemented using LFHCAL. You can access it here:

https://github.com/eic/epic/tree/negative-HCal-dev

use this configuration:

https://github.com/eic/epic/blob/negative-HCal-dev/configurations/backward_hcal_LFHCAL_geo.yml

I removed some of the modules that overlapped with collar, so it's smaller than LFHCAL. We can think about adding extra 4M (4 tile) modules in a few places (also in the center). I think, it may be good to check with project mechanical engineers on what exactly they implemented. For now, we still plan to use a simplified version to optimize the geometry, but will switch to this one once decided.

Best regards, Leszek

Hi All,

 

This is a reminder for our meeting today at 2pm EST.

 

Pre-TDR Assignments:

• Sam: neutron efficiency
• Tianhao: Simulation vs. CMS data, impact of tile uniformity
• Maria: intro/overview of design optimization
• UIUC: Updates to muon ID and muon plots
• Leszek: updates to sampling fraction and geometry description. Update into plots to include neutrons / muons and mean energy for the tail catcher region
• CTU (Sasha/alexander/Subadip): Upate plots similar to DAC presentation to show the position resolution (5x5, 10x10, 15x15) and the Delta Rxy distribution.
• Yevhenia: nHCAL performance evaluation and tests

 

I have a version of the pre-TDR with only the nHCAL that we can use to draft before pushing our updates to the official epic pre-TDR document:

During the meeting I can add emails for edit access.

Besides the pre-TDR assignments, I would like to revisit a few things wuickly from last week since attendance was rather low last week. Other contributions are welcome, please add your item to the agenda or let me know.

Please upload any slides by the time of the meeting. Talk to you soon.
