Calculation of Emittance Exchange by Wedge Absorbers with Associated Beam Effects for Intensity Frontier Experiments
Intensity in the g-2 ring at Fermilab is most severely restricted by its small energy acceptance. The g-2 experiment is exploring the use of wedge absorbers to reduce the energy spread of the μ beam entering the ring. The absorbers increase the transverse emittance by emittance exchange and multiple scattering. Energy straggling, beam mismatch, and other effects can also reduce the effectiveness, and beam optics can be modified to improve performance. Linear models with corrections are used to estimate the changes in beam acceptances and compared with simulations.
