CERN PS Radial and Phase Loop Gain Analysis

Dataset containing measurements and simulations of the PS radial and phase loop. These were used to determine the proportional gains, determining the conversion from measured radial or phase offset to frequency steering, of both loops.

Contents:

Kick_Data: Measurements of the phase and radial loops. 

20degkick_staticphaseloop_C948_05(-2/-3).npz: Measurements of the phase loop acting on a single bunch (normally sent to the East Area) around 948 ms cycle time. In these datasets, the RF phase is offset by 20 degrees without adjusting the target phase of the phase loop.

40degkick_followingPL_C948_05(1-/-2/-3/-4).npz: Measurements of the phase loop acting on a single bunch (normally sent to the East Area) around 948 ms cycle time. In these datasets, the RF phase is offset by 40 degrees while adjusting the target phase of the phase loop accordingly by 40 degrees.

radial_loop_response_C910(-2/-3).npz: Measurements of the radial loop acting on a single bunch (normally sent to the East Area) around 910 ms cycle time. In these datasets, the target radial offset is set from 13.6 mm to 0 at 910 ms cycle time

Kick_Simulations: Simulations reproducing the measurements for different values of the loop gains.
