Bender componentModels a curved neutron guide.The entrance lies in the X-Y plane, centered on the Z axis. The neutrons will also leave the bender in the X-Y plane at the z-value r*Win, so you do not have to calculate the real exit coordinates and you do not need a new arm. The bender is bent to the negative X axis; it behaves like a parallel guide in the Y axis. There is no warning, if the input parameters are wrong, so please make sure that w,h,r,d,Win,k are positive numbers and k*d is smaller than the width w. Example values: w=0.05 h=0.12 r=250 d=0.001 Win=0.04 k=3 ma=3 mi=2 ms=2 See also Additional note from Philipp Bernhardt.
