Notice: Terminology used in this section follows conventions of Hall A Tech Notes JLAB-TN-02-012:
BigBite Chamber center position are surveyed with laser markers and a hand held laser meter. Error could be between 1mm to 5mm.
- Center of 1st Chamber Outer Aluminum Plate in BigBite Target Coordinate System:
- X= -0.072m
- Y= unknown
- Z=2.862m
- Bigbite Magnetic in BigBite Target Coordinate System:
- Front Shielding Plate @Z=1.590m
- At Beam Height, Edge of Bigbite Coil at Detector Side @Z=2.46m
