Zusammenfassung:NSRL storage-ring has been operated for fourteen years, The typical life time is 600 mins at 200 mA and 800 MeV. The new injection ceramic chamber, bend chamber, undulator and NEG pumps were installed, new vacuum measure and control system was debugged in 2002 summer, as part of NSRL phase II project to enhance the quality, stability and long-term reliability. The average pressure of storage ring is better than 2E-8 Pascal after 48 hour large current direct backout and 48 hour ion pumps operation, this better vacuum can benefit the phase II project's object, beam lifetime 600 mins at 300 mA and 800 MeV.
