SHMS Beam Line – Large SHMS/HMS Angles
(Configuration-1)
SHMS large angle is 10°
HMS large angle is 14.5°
These angles allow for larger stepped Beam Pipes to clear Magnets and 1.3 Scatter Angle

SHMS Beam Line – Large SHMS /Min HMS Angles (Configuration-2)
SHMS large angle is 10°
HMS minimum angle is 10.5°
This configuration has small diameter Beam Pipe to nest inside HMS Q1 at Min HMS Angle. Beam Pipe does NOT clear 1.3 Scatter Angle

3. Making the section of Beam Pipe the larger diameter will cause an interference with the HMS Q1 at Min Angle
The smaller diameter Beam Pipe selected for the HMS min angle just clears the HMS Q1
