* dimension of limitation

** Fluxreturn space radius 90 - 270cm

** crystat radius 0 - 144cm

* dimension of support structure

**  SIDIS LAEC radius 80 - 90 - 140cm
 +
 
 +
* note
 +
** 0. the inner radius of fluxreturn could be reduced to 85cm for
 +
** 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 then.
 +
** 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 90-140cm is for the 100cm2 size module and LAEC 80-90cm is for smaller and shorter modules to fill the triangle area down to 14.85 degree line.
 +
 
 +
== number of module ==
 +
* assume 100cm2 module area, calculate number of modules by module coverage, we get
 +
** PVDIS FAEC 1860
 +
** SIDIS total 1879
 +
*** SIDIS FAEC 1464, SIDIS LAEC 415 (about 360 regular module, 55 small module)
 +
 
 +
* ANL design hexagon layout for FAEC has module about 1750 [https://www.dropbox.com/sh/szhmyaslhocu3ax/u3Q29_Y331]

* So 1800 module in total is good guess
