The 12 GeV equipment
Hall D – GLUEx detector for photoproduction experiments
Hall B – Large acceptance detector CLAS12 for high luminosity measurements (1035cm-2s-1)
Hall A – High Resolution Spectrometers and new multipurpose large acceptance detectors
Hall C – Super High Momentum Spectrometer (SHMS) and dedicated equipment
✴ short range correlations, form factors, and future new experiments: SOLID, MOELLER, SBS
✴ precise determination of valence q properties in nucleons and nuclei
✴ Understanding nucleon structure via GPDs and TMDs and hadron spectroscopy
✴ explore origin of confinement by studying hybrid mesons

SBS Tracker: summary• Participants:
• INFN/BA – gas system and test• INFN/CT – GEM assembling, mechanics, test, analysis• INFN/GE – electronics design • INFN/ISS – design, test, analysis and coordination• INFN/RM1 – Silicon tracker• JLab, Glasgow, UvA, Ruthers, UNH, CMU – SBS collaboration
• Funding: (prototyping and realization) 1 M$
• Status: most of the components procured or ordered; GEM assembling underway; characterization in progress. Expected installation 2015 (delayed by JLab/HallA schedule)
• Note: project delayed by ~ 1 year – due mainly to foil delivery
and first quality check failures. Do not affect JLab plan!
