  As a natural extension of the Beijing Electron-Positron Collider (BEPC), the BEPCII project has started its construction since the beginning of 2004. The BEPCII will operate in beam energy of 1-2.1 GeV, its design luminosity is 1*1033cm-2s-1 at 1.89 GeV with double-ring structure. The upgraded collider will also serve as a synchrotron radiation source with higher beam energy and intensity than the BEPC. Some key technologies, such as superconducting RF system, low impedance vacuum devices, superconducting micro-beta quadrupoles, etc. are developed. The injector linac reached its design specification by the summer of 2006. Most storage ring components have been manufactured, installed and tested. The final checkout of the storage ring subsystems is underway. For the delay of the cryogenic and high current test of the superconducting quadrupoles, the commissioning of the storage rings will be started with normal magnets in the interaction region in autumn of 2006. The project is scheduled to complete in 2008. This paper will present the updated status and preliminary commissioning results of the BEPCII.

  The progress of two RFQ accelerators at Peking University is presented: one is Separated Function RFQ (SFRFQ), which separates the focusing and acceleration of traditional RFQ to get higher acceleration efficiency. The first prototype of the SFRFQ is designed to accelerate O+ from 1MeV to 1.5MeV and used as a postaccelerator for ISR RFQ-1000 (Integral Split Ring) [1]. The other is high current deuteron 201.25MHz RFQ, it will accelerate 50mA D+ beam to 2MeV with a duty cycle of 10%. The design study of SFRFQ and high current Deuteron RFQ accelerator are outlined.
