Abstract

Abstract : Commissioning and first‐year operational results of the MAX IV 3 GeV electron storage ring, the first synchrotron light source to make use of the multibend‐achromat lattice to achieve ultralow emittance and high brightness, are presented. Abstract : The MAX IV 3 GeV electron storage ring in Lund, Sweden, is the first of a new generation of light sources to make use of the multibend‐achromat lattice (MBA) to achieve ultralow emitance and hence ultrahigh brightness and transverse coherence. The conceptual basis of the MAX IV 3 GeV ring project combines a robust lattice design with a number of innovative engineering choices: compact, multifunctional magnet blocks, narrow low‐conductance NEG‐coated copper vacuum chambers and a 100 MHz radio‐frequency system with passively operated third‐harmonic cavities for bunch lengthening. In this paper, commissioning and first‐year operational results of the MAX IV 3 GeV ring are presented, highlighting those aspects that are believed to be most relevant for future MBA‐based storage rings. The commissioning experience of the MAX IV 3 GeV ring offers in this way an opportunity for validation of concepts that are likely to be essential ingredients of future diffraction‐limited light sources.
