Changes and Additions to Related Programs

• beamLifetimeCalc now optionally uses the haissinski program to compute bunch lengthening. One can now vary additional quantities (beam energy, energy spread, and rf voltage) using values from an SDDS file.
• elegantRingAnalysis improvements:
  • Added collective effects tab with Haissinski equation, IBS, and space-charge tune shift.
  • Added floor coordinate computation to basic ring analysis.
  • Added printout of radiation integrals for basic ring analysis.
  • Added optional auto-creation of PNG files for each plot.
• haissinski improvements:
  • Added -harmonicCavity option, allowing inclusion of a second rf cavity with a higher harmonic.
  • Added -superPeriod option.
  • Modified iteration algorithm to actually honor the convergence criterion, resulting in more reliable convergence.
• ibsEmittance improvements:
  • Reduced the default target to $10^{-6}$, and made the tolerance 1/100 of the target, to get better convergence when IBS is weak.
  • Added the rf voltage to the output file.
• sddsbrightness improvements:
  • The default method is now actually Dejus' method, consistent with the usage message. Previously, default method was Borland's method.
  • Fixed bug in Dejus method implementation: the value of $\gamma$ was not being used consistently. Rather, in some places, a fixed energy value of 7 GeV was used.
  • Fixed a bug that led to multiplication of the current by 1000 for each pass through the main loop. This would affect calculations with multipage input files. Roger Dejus helped in finding this bug.
  • Added feature whereby the parameter ey0 from the twiss file is accepted for the vertical emittance, if it exists.
