5 Hall A UVA/PT Beam Line Chicane Tungsten calorimeter SEM BPM BCM Moller Target center Fast raster EP Slow raster 85cm 10 m 4 m Chicane Design : Jay Benesh (JLab CASA) Two upstream Dipoles, one with vertical degree of freedom. Reuse the dipoles from the HKS experiment. Utilize open space upstream of target. Minimal interference with existing beamline equipment. UVA/Jlab 5 T Polarized Target Upstream Chicane and supports Slow raster and Basel SEM. Instrumentation for 50-100 nA beam. Local beam dump. Hall A Septa. Major Installation
