The anti-solenoid compensation of the CLIC detector solenoid using IRSYN

The detector solenoid of CLIC causes a range of aberrations on the beam at the interaction point, particularly due to its overlap with the final focus magnets. These effects are corrected using antisolenoid correction coils on the final quadrupole before the collision point. In this note, we use the interaction region beam dynamics code IRSYN to compute the impact of the SiD solenoid on the beam and benchmark the anti-solenoid correction. We find the correction is achieved, with a small residual amount of beam aberration which is correctable using the beam delivery system. This provides a validation of the correction and a benchmark of IRSYN to existing codes
