The Fermi_Chopper component

Fermi Chopper with curved slits.

Identification

• Author: Andrew Garrett
• Origin: KEK (Japan)
• Date: 26 Nov 1998
• Version: 1.01
• Modification history:
  • EF, Mar 08th, 2000 : corrected the 'max' pb

Description

 Fermi Chopper with curved slits.  All slits have the same radius
 of curvature.

 Note:  w and r_slit should have opposite signs.  This routine 
  checks for this, and ensures the signs are opposite.  Nu is
  assumed to have the correct sign, and r_slit may be changed.
This component was previously called Curve_fe.comp.

See also Additional note  from Andrew Garrett [agarrett@ccbsf0.kek.jp].
