Automatic magnetic cycle editor for the CERN PSB

The main horizontal bending field in the CERN PSB synchrotron is programmed as a function of time called the “magnetic cycle”. The creation of such a cycle takes into account too many parameters to empirically elaborate it. In the present context with Linac 2 as the injecting machine, there is typically only one operational cycle used for all proton beams. The foreseen operation of the PSB with an extraction kinetic energy of 2 GeV (instead of 1.4 GeV as at present), together with a possible doubling of the injected beam charge with Linac 4, pushes the rf and the magnetic setups towards new limits. Using the existing hardware to achieve higher performances means an optimisation of the magnetic cycle. This note describes an application creating the synchrotron magnetic cycle from different input parameters, either equipment or beam related.
