[Erd108] [External] MPGD-DSC General meeting - Thursday October 2nd at 9 am

[Matthew Posik]

Hi All,

Here is the "Tracking in Backgroud" study I mentioned during today's meeting done by Shujie: https://urldefense.proofpoint.com/v2/url?u=https-3A__indico.bnl.gov_event_29753_contributions_113484_attachments_64699_111154_background-5Fanalysis-5FtrackingWG-5F09112025-2D2.pdf&d=DwIFAg&c=CJqEzB1piLOyyvZjb8YUQw&r=6nBhCQ9asnI7Gb72jBWQ4g&m=kKOGfNal4wzqyQNnWX-XQVyUxcj28nPul00OoEMExo6cEUibqCkZ95RP6rvlHQlP&s=eIQ5RacPMqtfkwbrp3vRIdlN6LHA_Ic9lL_ru_O9gEQ&e= 

Slide 3 shows the different distributions, where the sync. rad is by far the dominate source (just outside the beam pipe surface).

There are ROOT files available that merge signal + background, which are produced in the sim campaigns and can be found using the method discussed in the first couple FAQs: https://urldefense.proofpoint.com/v2/url?u=https-3A__eic.github.io_documentation_faq.html&d=DwIFAg&c=CJqEzB1piLOyyvZjb8YUQw&r=6nBhCQ9asnI7Gb72jBWQ4g&m=kKOGfNal4wzqyQNnWX-XQVyUxcj28nPul00OoEMExo6cEUibqCkZ95RP6rvlHQlP&s=SC_nKVFMMY9sVcQtRnWfKneYISubS-NqzkJpzXP-IHA&e= 

For example:  There is a merged background file at:
volatile/eic/EPIC/RECO/25.07.0/epic_craterlake/BACKGROUNDS/MERGED/HEPMC_merger-1.0.2/10x100/RealisticSignalPerFrame/HEPMC_merger-1.0.2_bgmerged_RealisticSignalPerFrame_MinBias_pythia6_10x100_egas_bgas.0030.eicrecon.edm4eic.root

One can also access individual background rootfiles as well. These files will contain the raw and reco hits for each detector.

My understanding is that with the October campaign these rootfiles will have all backgrounds merged.

Thanks,
Matt
