1. Early Career Internal Review Measurement of Double DVCS using SuperBigBite Spectrometer Nuclear Physics Alexandre Camsonne

2. Early Career Internal Review Executive Summary/Abstract Measure Double DVCS in muon channel at high luminosity Muon channel allows to increase luminosity since muons can go through large amount of materials Build a bulk Micromegas Laboratory for R&D for muon detector Use 2D shower profile to discriminate between pion and muons using Micromegas readout 1 plane 2m x 1m with 10 cm lead Reuse SuperbigBite magnet, GEM chambers and Hadron calorimeter and add 3 layers of materials and 2D trackers with Neutron detector lead wall

3. Early Career Internal Review Specific Scientific Aims Better constrain GPDs by having data at xi different from x Allow easy interpretation of the data by having muons in final state Can use as base for muon ID for larger acceptance detector –CLAS12 –SoLID

4. Early Career Internal Review Sampling calorimeter Prototype of hadron calorimeter using the Micromegas technology for Hadron Calorimeter for EIC with Annecy IN2P3 laboratory 1 m3 detector with 40 layers of iron/micromegas Most cost in readout electronics
