 -  Angle @ TC Mirror and The vertical interval of Direct Beam and Reflected beam

Angle @ TC - Mirror1 [mrad]	Position @ TC-Slit [mm] (from Direct Beam)
1.25	+2.28750
3.00	+6.90000
4.00	+9.20027
5.00	+11.50043

   Distance Center Position @ Mirror1 - Mirror2 : 1150 [mm]
   Position @ TC - Slit [mm] = 1150 * tan2 * q




 -  SetUp Axis @ TC Mirror

	Retract Pos.	5mrad Insert Pos.	3mrad Insert Pos.
TC - Mirror1 (x, z)	(0, -5)	(0, 0.0)	(0, 0.6)
TC - Mirror1 (qx, qz)	("free", -0.01142)	(5.0, -0.01142)	(3.0, -0.01142)
TC - Mirror2 (x, z)	(0, 10)	(0, 11.4)	(0, 7.1)
TC - Mirror2 (qx, qz)	("free", 0.2229)	(5.0, 0.2229)	(3.0, 0.2229)

  ( It is a reference value to the last. )

   If you insert the TC - Slit,
   You shold change the center position of it.



 -  Focusing Condition



   When mirror condition is Mirror for 5mrad,
   focusing Length is set to 48.5m
  ( When use Paraboloidal surface )

   Focusing Length is proportional to an sin q,
   In this case, F = 12.03m .

   So, The angle of TC Mirror is following.

   48.5 : 12.03 = 5 : x,     x = 1.24 [mrad]



L1 = Distance between "Light Source" and "Center Pos. @ TC - Mirror2"
L2 = Distance between "Center Pos. @ TC - Mirror2" and "Target Pos."
