Design criteria
The Design Criteria is to develop all the necessary dimensions from the known dimensions.
The known dimensions are
• Distance from target to first sense wire plane along a ray which is normal to the end plate = 4746.5 mm
• Chamber Tilt Angle = 25 Degrees
• Maximum Scattering Angle = 45 Degrees
• Minimum Electron Scattering angle = 5 Degrees
• Distance between the two Adjacent Pieces = 160 mm
The coordinate system in described in the attached PDF file:Media:CoordingateSystemR3.pdf
