Highlights of What’s New in Version 30.1, 3 Aug. 2016

Here is a summary of what’s changed since release 30.0

Fixed a bug in Touschek scattering simulation (TSCATTER element and touschek_scatter command) that resulted in the random multipole components of KQUAD and KSEXT elements being re-randomized for each TSCATTER element.

Fixed a bug introduced in moments_output computations when CSBEND elements were present with non-zero values of ETILT. Reported by V. Sajaev (ANL).
Fixed a bug in Touschek scattering simulation (TSCATTER element and touschek_scatter command) that resulted in the random multipole components of KQUAD and KSEXT elements being re-randomized for each TSCATTER element.

Added edge multipoles to KQUAD element. This necessitated some rearrangement of the code, so results might be slightly different even if this feature is not invoked.
Added I/Q mode feedback to the RFMODE element.

Implemented exact normalized emittance calculations for the sigma output file of the run_setup command and in WATCH output in parameter mode. J. Bjorklund pointed out the lack of calculations in the parallel version.
Fixed bug in assignment of particle ID values when using Halton sequences in the bunched_beam command.

The program abrat (“Asymmetric Bend RAy tracing”) was added. It allows tracking electrons through 2- and 3-D magnetic field maps. It is a commandline version of the BRAT element.
The script ionTrapping was added, providing simple ion trapping calculations for uniform bunch trains. J. Calvey (APS) helped with debugging.
The script computeSCTuneSpread was added to allow computation of space-charge tune spread.
The script radiationEnvelope now computes envelopes for central cone flux.
