1. MPGD Services by Francesco:

As the EPIC MPGD design is under development, could not provide the details on the services right now. Use the ATHENA design as the reference and provide the layer out of the service parts per module. Need simulation with background and strip readout implementation in simulation to help answer the MPGD service requirements.

2. EPIC tracking performance updates in DD4HEP by Wenqing:

Use the latest EPIC detector design with the material map and the 1.7T B field. Track reconstruction using truth seeding. Studied the tracking momentum dependent momentum resolution in fine pseudorapidity bins. Results achieved from DD4HEP full simulaiton are consistent with fast simulation results provided by Ernst. Observed momentum resolution drop significantly at very low momentum and saw hot region in the pseudorapidity region s of 1.5<|eta|<1.7. Further investigation is underway. Suggest to include the number of hits per track QA studies.

3. Change to disks configuration in the electron direction by Ernst:

From the integration requirement min = -1186cm, the siliocn disks in the electron going direction is optimized. The electron enedcap silicon disk location are z = -25cm, -45cm, -65cm, -90cm, -115cm.
