2 Outline CLAS12 Construction Status Project Schedule and Tentative Run plan The path to running BONuS12

3 12 GeV Upgrade Project New Hall Add arc Enhanced capabilities in existing Halls Add 5 cryomodules 20 cryomodules Upgrade arc magnets and supplies CHL upgrade Completion of the 12 GeV CEBAF Upgrade was ranked the highest priority in the 2007 NSAC Long Range Plan. Upgrade is designed to build on existing facility: vast majority of accelerator and experimental equipment have continued use. Maintain capability to deliver lower pass beam energies: 2.2, 4.4, 6.6…. Project Scope (~95% complete) : Doubling the accelerator beam energy - DONE New experimental Hall D and beam line – DONE Upgrades to Experimental Halls B & C (89% & 86%) TPC = $338M

4 CLAS 12 Base equipment Forward Detector (FD) - TORUS magnet (6 coils) - HT Cherenkov Counter - Drift chamber system - LT Cherenkov Counter - Forward ToF System - Pre-shower calorimeter - E.M. calorimeter Central Detector (CD) - SOLENOID magnet - Barrel Silicon Tracker - Central Time-of-Flight Beamline - Targets - Moller polarimeter - Photon Tagger Upgrade to base equipment - MicroMegas - Central Neutron Detector - Forward Tagger - RICH detector (1 sector) - Polarized target (long.) - BONus12 MM CND 4

5 CLAS 12 - Central Detector Integration of BoNus in CLAS12/CD requires early coordination with technical team.

6 Status of Hall B Forward Carriage FTOF1a, FTOF1b, PCAL and EC essentially operational 2+ years prior to scheduled beam commissioning. Beam Line Instrumentation Commissioned during HPS run up to Faraday cup, BPMs, harps, halo counters. Additional beam line components to be installed beginning 10/2015 TORUS Magnet Installation 6 coils and 6 pairs of hex beams installed in Hall Spare coil cryostated and factory disassembled Full Torus commissioned and field mapped 7/2016. SOLENOID Magnet 2 nd of 5 coils in fabricated Delivery of Magnet to JLab ~5/2016 Expected to be operational ~8/2016
