GRAVITATIONAL-WAVE INDUCED EFFECTS IN STORAGE RINGS BEAM DYNAMICS
Since Einstein predicted the existence of gravitational waves in nature, more than eighty years passed. Several methods such as Weber antenna, laser interference to directly detect the gravitational waves have been proposed and developed. Unfortunately, until1 now, no confirmative gravitational wave signal has been observed directly. Here, we propose a new method to directly detect the gravitational waves by monitoring the motion of charged particles in the storage ring. Suppose that a plane gravitational wave is incident on a simple quadruple oscillator consisting of charged particles moving in a storage ring. The metric of spacetime with a plane gravitational wave propagating along zaxis is given in c = 1 unit by

title: Einstein'S General Relativity Effects on Beam Dynamics in a Storage Ring
abstract: In this paper we will discuss Einstein's tide force predicted by Einstein's general relativity, how the new tide force would affect the beam orbits in a storage ring, and how to pick up and recognize it from the beam signals in a storage ring. The result shows this effect can be accumulated by the charged particle beam in a storage ring, it is a very interesting result.

title: HIGH FIELD EXPERIMENT OF 1.3M-LONG X-BAND STRUCTURE
abstract: Two 1.3m-long X-band accelerating structures were made to study the fabrication of the structure for the main linac of linear collider. One of the structures is being highpower tested to confirm the basic high field performance of such a full-scale structure. Various experimental instrumentations were carefully prepared; recording the RF pulses as the break down occurs, recording the timing, position and strength of X-rays along the structure, measuring dark current towards upstream and downstream along the beam axis, etc. Using these monitoring devices, the process of conditioning for the structure until reaching the specified field level or beyond is being studied. In the present paper are described those instruments and a preliminary conditioning result up to a power level of 1 MW.

title: KLYSTRON AND MODULATOR UPGRADE FOR BEPCII LINAC
abstract: An upgrade of the RF power source is now processing at the BEPC Linac in order to increase the acceleration energy from the present 1.3Gev up to the1.89Gev required for the BEPCII. It was decided that most of the existing klystron and all modulators should be reinforced so as to be capable of producing pulses with 110MW peak power and 6.3µs pulse duration. This paper describes the detailed concerning of the klystron and modulator upgrade.

title: Measurement of the $B^\pm \to \rho^\pm \pi^0$ branching fraction and direct CP asymmetry
abstract: An improved measurement of the process B+- --> rho+- pi0 is presented. The data sample of 211/fb comprises 232 million Y(4S) --> BBbar decays collected with the BaBar detector at the PEP-II asymmetric-energy B Factory at SLAC. The yield and CP asymmetry are calculated using an extended maximum likelihood fitting method. The branching fraction and asymmetry are found to be BR(B+- --> rho+- pi0) = [10.0 +- 1.4 (stat) +- 0.9 (syst)]x 10^-6 and Acp(B+- --> rho+- pi0) = -0.01 +- 0.13 (stat) +- 0.02 (syst), superseding previous measurements. The statistical significance of the branching fraction is calculated to be 8.7sigma.

title: Measurement of CP asymmetries in $B^0 \to K_s 0 \pi^0 \pi^0$ decays
abstract: We present a preliminary measurement of the time-dependent CP asymmetry for the neutral B-meson decay into the CP = +1 final state KS pi0 pi0, with KS-> pi+ pi- and pi0-> gamma gamma. We use a sample of approximately 227 million B-meson pairs recorded at the Y(4S) resonance by the BaBar detector at the PEP-II B-Factory at SLAC. From a maximum likelihood fit we extract the mixing-induced CP-violation parameter S = 0.84 +/- 0.71(stat} +/- 0.08{syst) and the direct CP-violation parameter C = 0.27 +/- 0.52(stat) +/- 0.13(syst}, where the first uncertainty is statistical and the second systematic.
