Rong Huang code, version 2.0

This program calculates single-bounce capillary (SBC) focusing profile with the formulas given in the paper "Single-Bounce Monocapillaries for Focusing Synchrotron Radiation: Modeling, Measurements and Theoretical Limits", R. Huang and D. H. Bilderback; J. Synchrotron Radiation 13 (2006) 74-84. ( 1347kb).
Basic approximation used in the formula development include:
      (1) Gaussian source (non slit source)
      (2) Gaussian profile of slope error blurring effect
      (3) Capillary ellipse profile long axis a is >> short axis b.
      (4) Capillary to source distance >> capillary length.
      (5) Small source size compared to capillary length.
      (6) Diffraction and interference effects are not considered.
