New beamlines will be installed at the AS in the next few years and photon BPMs will be part of the front end design. A theoretical study of the potential benefits of a multi-bladed photon BPM design has been simulated using beam profiles from SPECTRA. The results show that it is possible to remove the gap/field dependence of the photon BPM by a least squares fit of the distribution, in this test case a Gaussian distribution, to the beam profile sampled by the multiple blades.

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.
