Solid Detector Dimension
From Hall A Wiki
Introduction
The SoLID layouts with different configuration are shown here.
The standard setup plot can be download from http://hallaweb.jlab.org/12GeV/SoLID/download/sim/setup/
coil center at z=0, positive Z axis is going downstream along beam, x and y axis is according to right hand rule.
Previous Layout
SoLID CLEO (based on CLEOv8 field map, updated in 01/30/2015)
CLEOv8 field map is based on more realistic design with CLEO-II.
The magnet and yoke will fit both PVDIS and SIDIS/JPsi configuration.
The detector has various small change to fit into new design, please refer to the change at slide 7 and 8 of CLEOv8 update pptx pdf
