MEIC Working Group Activities

Subscribe to meic_np@jlab.org (nuclear physics topics) and/or meic@jlab.org (accelerator + NP)

and/ormeic_det@jlab.org (detector)

If you subscribe, you get the mail to inform how to connect to meetings.

Or, go to the eic@jlab wiki pages: https://eic.jlab.org/wiki/index.php/Main_Page • General meetings: Fridays 9:30 – 11 am (as announced)

some of these meetings are joint, to discuss items of relevance to all,some of these are nuclear science/discussion oriented

• Detector meetings: Thursdays 1:00 pm (weekly)(organizers: Zhiwen Zhao (ODU, zwzhao@jlab.org) and Pawel Nadel-Turonski (JLab, turonski@jlab.org))

• Accelerator R&D meetings: Thursdays 2:30 pm (weekly, following previous)(organizer: Yuhong Zhang (JLab, yzhang@jlab.org))

Life may be easier if you first request a JLab user account from:http://www.jlab.org/div_dept/physics_division/researchers.html

Involving users in the MEIC detector

• Have detailed layout for extended interaction region – Implemented detectors using standard JLab simulation

tools in GEMC with Fast Monte Carlo capability

– Standard JLab software makes transition easy for users

– Users can take ownership of various subsystems

– Users can ensure appropriateness of detector for their science of interest, and/or optimize

• Support for users taking part in the Generic EIC Detector R&D program– Assist in proposal preparation

– Infrastructure for R&D, e.g. 5T sensor test facility re-using existing magnets

• Regular meetings with user participation

– General Friday meetings (announced)

– Weekly Thursday detector meetings

• Mailing lists:

– meic_np@jlab.org

– meic_det@jlab.org

Optimizing User Involvement

• JLab facilitates by providing the extended detector and interaction region layout and CAD design

• JLab also provides the generic GEMC/GEANT4 simulation framework and coordination.

• The MEIC detector development, and ancillary system development (polarimetry, luminosity measurements, ultra-forward detectors), is a user-driven effort.

• It often relies on interaction with JLab engineers and designers to verify if “things fit”.

• Users can use this framework to optimize the detection schemes for their science of interest.

We solicit suggestions from users how to make it easier for them to get involved.
