I uploaded some slides (also attached) that we can discuss at next week’s meeting. Basically re-ran all of the SynRad simulations using the new 5.2 lattice files (18GeV and 10GeV) supplied by Holger and worked on optimizing the wall steps in the electron beam pipe leading up to the detector to minimize scattered photons from the last dipole (DB6). Alexei is going to run some simulations to determine the impedance impact of the new step geometry. Have a great weekend.

Thanks,
