Show room on map

Present: Ivan, Markus, Helga

Updates on code:

- bug fix on solver type

- merged modifications on Profile (docs, casting)

- merged Konstantinos' histogram with dynamic memory allocation

- added emtpy tracker for synchrotron radiation; Ivan tried with adapted TC13 to test this new option but it still bugs. Suggestion: pass negative harmonic to flag empty station

Ivan:

  • fixed small bugs in SR; to be merged
  • in ring, initialisation of unused eta functions has to be matrix instead of array
  • TC13 to be converted to unittest for decay rate and equilibrium bunch length

Markus:

  • TWC induced voltage analytically is very long/ugly, so not very useful for unittest
  • MDs on OTFB ongoing
    • Bunch profiles, Vcav (I,Q) acquired
    • Spikes with FF seen at injection
  • Ring unittest with different input types

Helga:

  • Benchmarked InducedVoltageFreq(), InducedVoltageTime(), Induced voltage from wake and impulse response in OTFB. Good agreement. Slight discrepancy to be traced down.

PLANS:

Ivan -> test tracking with different option

Markus -> help with OTFB
