General EEEMCal Meeting Summary 5/17/21

EEEMCAL MEETING - 17 MAY 2021

PARTICIPANTS: Vladimir, Bruno, Carlos, Crytur USA, Miroslav, Gabriel, Hamlet, Hrachya, Nathaly, Pete, Petr, Renee, Richard, Tanja, Rosi, Sasha, Douglas, Cristiano, Lei, Michael

MEETING UPDATES

• EIC@IP6 update (Vladimir)

• Presented EEEMCal and possible contributions
• Comments/questions from EIC@IP6 group:

• reference technology for outer EEEMCal
• need to pay attention to calibration and monitoring strategy for keeping high precision constant term in the long run - c.f. PANDA EMCal

• Calorimeter WG meetings will start this week

• ECCE Update

• Calorimeter WG will meet Tuesdays 8-10am ET

SIMULATION UPDATES

• EEEMCal Fun4All implementation (Carlos)

• Hybdrid implemented - work ongoing on clustering

• Homogeneous barrel EMCal (Nathaly)

• Implementation of the barrel homogeneous EMCal starting from a cylinder that will be segmented and given a suitable depth etc.
• Currently investigating hits from Geant4
• Another option: received a segmented model of the PANDA EMCal - more complex geometry than needed fro EIC - keep as backup option for now

• Ongoing and planned studies:

• Vardan and AANL team
• Renee: e/pi separation
• Gabriel and team
• Cristiano: detector design optimization AI supported

• EIC simulation frameworks for EEEMCal:

• Fun4All for near term investigations that do not need a specific framework, e.g., e/pi separation studies, etc.
• DD4HEP for longer term - requires building structure from ground up - more detail from EIC SWG
• Standalone simulations for investigations that do not require the details of other detectors/materials etc.
• ESCALATE for AI supported detector design optimizations that do not depend on the simulations framework

• Action item:

• review list of simulation open tasks and add/edit
• add contacts on simulations Wiki page

PROTOTYPE BEAM TESTS

• Jefferson Lab (Tanja)

• start scheduled for August 24th and run will until mid-December 2021
• EEEMCal runs are expected end of September for three weeks and mid-November until the end of the run
• Currently JLab still in Medcon5: currently no new users admitted for beam tests - stay tuned for status changes during summer/fall

• DESY (Douglas)

• Program is running - new requests for beam tests accepted for the fall
• Request has been submitted for November 2021 (2 weeks)

SIPM+PWO DETECTOR (Irina, Olivier, Bruno)

• Discussion of questions on specifications

• Energy resolution - does it include general readout characteristics? - here, assumed PMT
• Collision rate is ~0.5 MHz, but rate per channel is smaller (~100 kHz) - synchronous: can assume that either have event or not
• Pulse shape - send more information on HallD trigger system (fADC, gates, etc.)

• Simulation framework

• Very interesting for simulating configurations and optimize before test bench and beam measurements
• How to include beam test data in the simulation?

• Action items:

• Get additional clarifications on pulse shape
• Make SiPM+PWO model
• Point of contact assignment (for now): Tanja Horn

VISUALIZATION OF EEEMCAL

• Visualization tool introduced

• Some work remains to be done with global detector(s) configuration to finalize outer dimensions of EEEMCal, e.g., orientation of DIRC

• Once outer dimensions are finalized EEEMCal team will start design of EEEMCal details

NEXT MEETING: MONDAY 7 JUNE AT 8:30AM ET
