The project DELSY, a 1.2 GeV synchrotron radiation source [1] is being under development at JINR, Dubna, Russia. This source is dedicated to the investigations on condensed matter physics, atomic physics, biology, medicine, chemistry, micromechanics, lithography and others. For DELSY storage ring the layout with four straight sections was chosen. Every quadrant consists of MBA-structure and two halves of straight sections. The circumference of the ring is about 136 m; the emittance of the electron beam is 11.4 nm. The effects of the very strong wiggler of 10 T and undulator (0.75 T, 150 periods) on beam parameters are discussed. The results of influence of machine imperfections on the optics properties are given.

The former Antiproton Collector (AC) at CERN has been transformed into an Antiproton Decelerator (AD) to supply high quality antiproton beams with a momentum of 100 MeV/c (kinetic energy of 5.3 MeV) [1]. As in AC, antiprotons are injected at 3.57 GeV/c and cooled by stochastic cooling system. To facilitate the deceleration and to prepare a small emittance beam for the experiments, stochastic cooling at 2 GeV/c and electron cooling at 300 MeV/c and 100 MeV/c has been incorporated. The required optics modifications are described and the results of machine commissioning are discussed.
