Abstract
At MAX IV Laboratory, the Swedish Synchrotron Radiation (SR) facility, the largest of two rings operates at 3 GeV with a bare lattice emittance of 330 pm rad. Upgrade plans are under consideration aiming at a gradual reduction of the emittance, in three stages: a short-term with an emittance reduction of 20% to 40%, a mid-term with an emittance reduction of more than 50% and a long-term with an emittance in the range of the diffraction limit for hard X-rays (10 keV). In this paper we focus on the short-term case, resuming previous work on a proposed lattice that can reach 270 pm rad emittance, with only minor modifications to the gradients of the magnets of the present ring, i.e. without any hardware changes and all within the present...

At MAX IV Laboratory, the Swedish Synchrotron Radiation (SR) facility, the largest of two rings operates at 3 GeV with a bare lattice emittance of 330 pm rad.

In this paper we focus on the short-term case, resuming previous work on a proposed lattice that can reach 270 pm rad emittance, with only minor modifications to the gradients of the magnets of the present ring, i.e. without any hardware changes and all within the present power supply limits. Linear lattice characterisation and calculations of key performance parameters, such as dynamic aperture and momentum aperture with errors, are described and compared to the present operating lattice. Experimental tests of injection into this lattice are also shown. (Less)
