1. Topics for the discussion session 05/11/2015
How realistic are typical beam dynamics calculation to be used for predictions?
What are the inputs from beam measurements used?
What are the assumptions in typical calculations?
How are assumptions communicated to the operation crew and BI groups?
What are the basic beam observable needed for beam dynamics calculations?
To which details they are required?
E.g. Is the full transverse profile (which might be very ‘non-Gaussian’) useful
or only reduced quantities of statistical moments e.g. standard deviation?
E.g. For what beam parameter a single shot measurement are required e.g. within the same cycle is mandatory or are repeatable measurements possible which relay on reproducibility of the accelerator ?
What is the path from basic commissioning to reach of design goal?
Commissioning = prove of basic functionality of technical devices leading to
some beam-on-target
Design goals = optimal beam parameter reached
What information should be achieved during operation runs for offline analysis?
