Abstract
The beam commissioning of the 1.5 GeV electron storage ring of "NewSUBARU" started in September 1998. At the beginning of the commissioning the beam l ifetime was short because of the high beam-on pressure. The upgrade of the vacuum system including the replacement of the vacuum chamber of the insert ion devices and the addition of vacuum pumps was performed in 1999. As a re sult of the upgrade the beam lifetime was drastically improved and the user experiments started in February 2000. (C) 2001 Elsevier Science B.V. All r ights reserved.
