Modified Elements

• Added super-elliptical apertures for ECOL and MAXAMP. A super-elliptical aperture is somewhere between an ellipse and a rectangle.
• Added one-sided aperture capability to the ECOL, RCOL, and MAXAMP elements.
• The SCATTER element now includes an optional scattering probability.
• Added a radius factor parameter for longitudinal space charge evaluation to the LSCDRIFT and RFCW element. The default value for this parameter changes the computations from the previous release, and was computed by J. Wu (SLAC).
• Added ability to control expansion of square roots in canonically-integrated elements. The default is no expansion, as before.
• The FRFMODE and FTRFMODE elements now optionally provide output of voltage in each mode as a function of time.
