TI - Septum Orbit Feedforward Correction at the AS J2 - Proc. of IBIC2020, Santos, Brazil, 14-18 September 2020 CY - Santos, Brazil T2 - International Beam Instrumentation Conference T3 - 9 LA - english AB - The leakage fields generated by the septum in the injection straight perturbs the beam by as much as 130 µm horizontally and 80 µm vertically during injection. Passive shielding with copper collars and Mu metal sheets has reduced the perturbation but not removed them. The remainder of the perturbation will be corrected using an active feedforward system. This report will discuss the design of the system and the effectiveness of the prototype.
