Book excerpt: The main design features of the PEP-II asymmetric two-ring electron-positron B Factory collider, built at the Stanford Linear Accelerator Center, are described. This facility will complete construction in June 1998. The high energy ring, completed in May 1997, has had 3 months of commissioning and successfully stored 0.75 A of electrons. The success of the high energy ring testing validates not only its ring components, but also the injection system, the RF system and the control system all of which are common to the two rings.

Book excerpt: PEP-II [1-9] is an ee− collider with asymmetric energies (3.1 and 9 GeV, respectively) in a 2200 m tunnel at the Stanford Linear Accelerator Center. The collider produces B mesons to study a particle physics effect called CP violation as well as other physics topics. PEP-II was completed in 1998 with the first luminosity generated in July of that year. The installation of the BaBar Detector was finished in May 1999. The overall layout of PEP-II is shown in Figure 1 and the interaction region of PEP-II in Figure 2. The accelerator parameters and achievements of the High Energy Ring (HER) are listed in Table 1 and those for the Low Energy Ring (LER) in Table 2. The two beams collide at a single point in the IR2 hall where the BaBar detector is located. Beam parameters at the best luminosity are shown in Table 3 and PEP-II milestones in Table 4. In August 1999 PEP-II passed the world's record for luminosity which was 8.1 x 1032/cm2/s. The present luminosity in PEP-II is 2.15 x 1033/cm2/s which is 72% of the design. In June 2000 PEP-II delivered an integrated luminosity of 150 pb−1 in one day, which is above the design integrated luminosity per day of 135 pb−1. Over the past year PEP-II has delivered over 12 fb−1 to BaBar. BaBar has logged over 11 pb−1. The present plan is collide until the end of October 2000 followed by a three month installation period.

This book was released on 2001-09-25 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers the first strong evidence of the existence of CP violation in neutral B decays extracted from sophisticated B factories in the US and Japan. It also holds out the expectation of rare B decays and D, K physics in the near future. In addition, new physics beyond the Standard Model is described. Both experimental and theoretical points of view are given.

Book excerpt: The PEP-II project, a joint proposal of SLAC, LBL, and LLNL, will involve an upgrade of the PEP storage ring at SLAC to serve as an asymmetric B factory. The upgrade will involve replacing the vacuum and rf systems of PEP, which will serve as the high-energy ring (containing 9 GeV electrons), along with the addition of a new low-energy ring (containing 3.1 GeV positrons) mounted atop the high-energy ring. The present design status of the project and a summary of recent R & D results are presented here. If approved, the PEP-II project is ready to begin construction in October 1993.

Download or read book PEP II Status and Future Plans written by and published by . This book was released on 2002 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The PEP-II B-Factory at SLAC has reached a luminosity of 4.6 x 1033/cm2/s and has delivered 94 fb−1 of data to the BaBar physics detector by the end of May 2002. PEP-II has delivered over 309 pb−1 in 24 hours and over 6.35 fb−1 in one month. The accelerator physics issues for these performance levels include electron cloud, beam-beam effects, parasitic beam-beam collisions, and RF beam loading. Upgrades to PEP-II are underway to increase the luminosity to 2 to 4 x 1034/cm2/s by FY2007. The accelerator physics effects that must be dealt with during these upgrades include RF loading, multi-bunch feedback, IR beta function, bunch length reduction, and interaction region vacuum chamber upgrades.
