Abstract
The dedicated VUV radiation source Super-ACO is part of the Orsay synchrotron radiation complex. The construction of this 800-MeV positron storage ring was started in 1982, and the first beam was stored on March 18, 1987. Super-ACO is expected to accommodate up to six undulators. The first, a 3.2-m-long optical klystron has already been operated between 500 and 800 MeV. A 1.3-m-long undulator has been recently installed. The experience gained during the three periods of operation is presented. From March to October 1987 measurements were taken of the machine properties in the low emittance regime, as well as performances in single and multibunch operation. In March 1988 the optical klystron was tested together with the commissioning of two beamlines out of a bending magnet. Starting from May 1988 two undulators and six beamlines progressively operated.
