چکیده
Suppression of head-tail effects on turn-by-turn BPM measurements V. Lebedev The study carried out for BLT proved that the head-tail motion excited by the machine chromaticity could seriously affect the performance of turn-by-turn BPM measurements. In this paper I consider how this problem can be alleviated for new Tevatron BPMs. Let us consider the case when the bunch, which initially was on the central orbit, is excited by a kick. In the case of linear synchrotron motion and Gaussian longitudinal distribution one can write the following expressions presenting the dipole moment distribution along the bunch ( )

Developing an Analytical Model and Simulation of The Contraflow Left-Turn Lane at Signalized Intersections
At some intersections, excessive queue lengths may spill out of the left-turn bay and block the through lanes, jeopardizing level of service for the entire intersection. One of the most effective plans recently presented by the researchers is the "Contraflow left-turn lane" (CLL) In this method, left-turn vehicles will use the nearest lane in the opposite direction in addition to the usual left...
متن کاملBeam Diagnosis and Lattice Modeling of the Fermilab Booster
Xiaobiao Huang Beam Diagnosis and Lattice Modeling of the Fermilab Booster A realistic lattice model is a fundamental basis for the operation of a synchrotron. In this study various beam-based measurements, including orbit response matrix (ORM) and BPM turn-by-turn data are used to verify and calibrate the lattice model of the Fermilab Booster. In the ORM study, despite the strong correlation b...
متن کامل2D Porous ZnO Nanosheets: One Pot Synthesis with Low Turn-on Field
Low turn-on field of 2.3 V/µm was found for the emission current density of 10 µA/cm2 from 2D porous ZnO nanosheets. High current density of 0.76 mA/cm2 was drawn at an applied field of 4.1 V/µm. The observed low turn-on field of porous ZnO nanosheets has been found to be superior to the other ZnO nanostructures reported in the literature. Also, the emission current stability over a period of 3...

Condition monitoring and protection methods based on the analysis of the machine's current are widely used according to non-invasive characteristics of current transformers. It should be noted that, these sensors are installed by default in the machine control center. On the other hand, condition monitoring based on mathematical methods has been proposed in literature. However, they are model b...
متن کاملO-10: Formation and Molecular Composition of The Sperm Head to Tail Coupling Apparatus
Background According to a worldwide survey in 2010 infertility affects 48.5 million of couples. In roughly half of the cases infertility is provoked by the male mate. Thus, a significant percentage of young men are infertile but the underlying causes are mostly unknown. Male fertility and reproduction success critically depends on proper formation of the mature sperm. Transmission of the geneti...
