520 _ _ |a Space charge induced micro bunch instabilities, amplified in cascadedbunch compression stages, spoil the phase space of compressed bunches and leadto unstable seeding. To “heat” up the bunch with an external laser and induce anuncorrelated energy spread to suppresses the micro bunching instabilities, a shortundulator will be installed in front of the first compression chicane. The undulator hasa planar hybrid magnet structure with 43 mm period length, 11 full periods, 22 mmminimum gap and a deflection parameter K of 1.52 (K = (eBλ$_u$) / (2$π$m$_{ec}$), withB - max. magnetic field amplitude, λ$_u$ - period length) to match the 534 nm laserwavelength at 146 MeV beam energy. The paper describes the undulator’s compactdesign, its control system and results of magnetic measurements and tuning.
