This paper introduces a new approach to measure the muon magnetic moment anomaly |$a_{\mu} = (g-2)/2$| and electric dipole (EDM) |$d_{\mu}$| at J-PARC facility. The goal of our experiment is |$a_{\mu}$| using an independent method with factor 10 lower momentum, 20 smaller diameter storage-ring solenoid compared previous ongoing |$g-2$| experiments unprecedented quality storage field. Additional significant differences from present experimental include 1000 transverse emittance beam...
The movement of biological fluids in the human body is a premium field interest to overcome growing biomedical challenges. Blood behavior shows different capillaries, veins, and arteries during circulation. In this paper, new mathematical relation for nano-layer flows with effect TiO2 Ag hybrid nanoparticles was developed. Further, we explain engineering phenomena role blood vessel system. improvement drug delivery systems by using low seepage Reynolds number associated expansion/contraction...
Abstract The Associated Proton beam Experiment Platform (APEP) beamline is the first proton irradiation facility to use naturally-stripped protons which come from H-beams interacting with residual gas in linac beampipe at CSNS. stripped current, order of 0.1% original H-beam and approximately 10 μA, should be measured precisely provide number for experiments. Therefore, a low-intensity current measurement system was developed considerations eliminate external interferences. An...
Abstract The emission of muonium ($\mu^+e^-$) atoms into vacuum from silica aerogel with laser ablation on its surface was studied various structures at room temperature using the subsurface muon beams TRIUMF and Japan Proton Accelerator Research Complex (J-PARC). Laser applied to produce holes or grooves typical dimensions a few hundred $\mu$m mm, except for some extreme conditions. measured rate tends be higher larger fractions opening shallower depths. More than reach rates similar...

Abstract The direct simultaneous detection of electron and positron bunch signals was successfully performed for the first time with wideband pickups a system at capture section SuperKEKB factory. interval between bunches, their lengths, intensities depending on phase accelerating structures were measured to investigate process maximally optimize intensity. results show that intervals in range 135–265 ps, line-order switch bunches axial direction clearly observed as function phase....
The development of a vertical kicker system is an important part three-dimensional spiral-injection scheme. beam injected at pitch angle few tens degrees was controlled by applying pulsed magnetic field using inside the storage magnet. stored muon then followed betatron motion around midplane magnet owing to weak focusing field. Accurate control kick crucial for minimizing amplitude oscillation. specifications and detailed design test bench are discussed herein.
Neutral uncharged molecules are affected by the electromagnetic field of a charged particle beam if they carry either an electric or magnetic dipole moment. The residual gas in accelerator pipe consists such molecules. In this paper we study their dynamics. Under few approximations, whose validity explore and justify, derive equations motion neutral invariants, determine conditions for these to become trapped beams as function beam-pipe temperature, compute resulting enhancement molecule...
