PyHEADTAIL Meeting #21
Jani presented the feedback module of PyHEADTAIL, details of use cases, implementation and benchmarks.
- Jani motivated the necessity to use advance feedback modeling in simulations
- Jani stressed that for novel systems pushing the performance of machines are probing limitations of feedback systems as well as
- It was discussed whether or not non-linearities could well be modeled in conventional systems. We agreed that the onset of the instability can be treated with a linear system.
- Jani went into explaining the details of the PyHEADTAIL feedback module.
- Kevin clarified that the example of using several pickups and kickers within the ring is not purely academic but was used for FCC studies. Gianni mentioned that several pickups are used today in the LHC.
- Jani showed examples of applications. He showed the example of the ADT signal processing. Kevin asked whether each of these individual processors is documented in the notebooks. Jani said that he would update the notebooks and refine parts of the documentation.
- Jani explained that all rules and regulations for the design can be followed in the core module.
- Jani gave some examples from MD results showing good agreement between simulations and measurements, including on end-of-fill MD featuring a feedback induced instability.
- Kevin asked how much additional time one must count if one want to include feedback system modeling.
- Nicolas asked about having an intermediate damper module having just the phase error in the place.
