Dimension and Layout

limitation

 Fluxreturn space radius 90 - 270cm
 crystat radius 0 - 144cm

dimension

 PVDIS FAEC radius 96 - 262cm
 SIDIS FAEC radius 96 - 262cm
 SIDIS LAEC radius 92 - 140cm

note
- 1. the inner radius of fluxreturn could be reduced to 85cm

Please note 1. The radius for LAEC and FAEC are just the range of minimum acceptance we want to cover. The actual physical size can be larger, but it's limited by available spaces. 2. the FAEC supporting structure is share between SIDIS and PVDIS experiments. While SIDIS needs from 96cm - 230cm and PVDIS needs 110cm - 262cm, the overall need is 96 - 262cm. 3. SIDIS FAEC needs to move upsteam 85cm to become PVDIS FAEC, so the supporting structure needs to allow the movement. Note at the before and after locations, the endcap nose shape changes. It's a concern if the supporting structure is connected to the endcap nose. If the supporting is only connected to the endcap donut (15cm thick iron), not the endcap nose, it won't be a concern any more. 4. LAEC needs to support on its own without putting force on cryostat and its supporting may need to share with GEM to stay within the limited space inside the solenoid. 5. The LAEC 92cm is the limit for the 100cm2 size module only. Below that, we need to put in smaller size modules to fill the triangle area as much as possible, but not cross the hypotenuse line at 14.85 degree.
