An outline is explained for hadron-physics projects at J-PARC, which is considered to be one of the flagship facilities in hadron physics from 2008. The facility provides an intensity frontier with 50 GeV proton beam for nuclear and particle physics. It could cover a wide range of hadron physics from strongly interacting many-body systems with an extended hadronic degree of freedom, strangeness...
متن کاملMullite-alumina functionally gradient ceramics
Cracks free mullite-alumina Functionally Gradient Ceramics (FGC) have been obtained by sequential slip casting of Mullite-alumina slurries with diserent mullite/alumina ratios. These slurries were prepared with 65 % solids content and viscosities rangingpom 10 to 40 mPa.s. 7he presence of cracks perpendicular to the FGC layers have been attributed to residual stresses developed because of the m...
متن کاملSurface Contamination of Alumina Ceramics by Carbon
Article history: Received: 01.05.2016. Received in revised form: 25.07.2016. Accepted: 06.09.2016. This study presents the results of investigating the cause of contamination of aluminum oxide ceramics (Al2O3) in the form of brown colored stain. Contaminated ceramic surfaces were examined with the scanning electron microscope (SEM) equipped with the Energy Dispersive Spectrometer (EDS). The res...
متن کاملPresent Status of the J-parc Accelerator
Construction of the Japan Proton Accelerator Research Complex (J-PARC), which consists of a 400 MeV Linac, a 3 GeV Rapid Cycling Synchrotron (RCS), and a 50 GeV Main Ring (MR), commenced in 2001. J-PARC is a multipurpose accelerator complex. The RCS uses 1 MW proton beams to generate pulse neutrons that will be used for various research projects ranging from basic science to applied science at ...
متن کاملPower Upgrade of J-parc Linac
The linac power upgrade program is now in progress, after a successful recovery from the earthquake disaster. The power upgrade includes an ion source, a RFQ, and a 400 MeV annular-ring coupled structure (ACS) linac. We started a full-scale development of a cesium-seeded RFdriven negative hydrogen ion source. The ion source extracted a beam current of more than 60 mA with a duty factor of 2.5 %...
