https://gitlab.psi.ch/OPAL/src/issues?scope=all&utf8=%E2%9C%93&state=closed&label_name=Feature%20request&milestone_title=OPAL%202021.1[New features in OPAL 2021.1]

  • New Undulator element with its own FDTD electromagnetic solver, making use of the (MITHRA) library (#535)

  • LOWENERGYTHR attribute (in [MeV]) for energy loss calculation by PARTICLEMATTERINTERACTION command (#83, #142)

  • Energy loss calculation and beam scattering are available for all light ions (#634)

  • Stopping power at low energy region (#634)

  • ALPHA particles are supported in BEAM command (#634)

  • ENABLEVTK option (default true) to control writing of voxel mesh output (#647)

  • OUTFN attribute has been added to Cyclotron and Source elements (#650)

  • Gas stripping is now available for DEUTERON beams and H2P beams in AIR (#665)

Code improvements

  • C++ revision to C++17 (#607)

  • Enables extra error checking in the form of precondition assertion (#627)

  • New Attribute type PreDefinedString (string enum) (#654)

Input file related changes

  • RING field map has been explicitly added as a cyclotron TYPE (#626)

  • COLLIMATOR and DEGRADER TYPE of PARTICLEMATTERINTERACTION has been renamed as SCATTERING (#633)

  • BEAMSTRIPPING element has been renamed as VACUUM (#633)

  • Particle masses supported in BEAM command are defined as standard constants (#646)

  • Since version 2.4 the DISTRIBUTION momentum input is changed to momentum (instead of energy). To avoid confusion, this is also made clear in the DISTRIBUTION command, INPUTMOUNITS = EV is changed to INPUTMOUNITS = EVOVERC (#649)

  • String input only accepted with quotes (#495), CONST STRING fmap = "fieldmaps/someFM.T7";

  • Variable names are now accepted for string attributes (#495), cav1: RFCavity, FMAPFN=fmap, ...;

  • The values of MB_BINNING and AMR_MG_NORM attributes have been changed (#495, OPAL/documentation/manual#58)

  • BEAM energy needs to be explicitly specified, P0 is no longer used as default (#655)

Output file related changes

  • More information has been added to the HDF5 file written by monitors (#503)

  • The unit of time in loss output file is changed from [ns] to [s] (#640)

  • The header of ASCII loss output has been modified (#650, OPAL/pyOPALTools#99)

  • DumpFields and DumpEMFields print attributes info in stdout (#651)

  • The units of cyclotron output field map 'eb.out' have been changed to [m] and [deg] (#662)
