\ensuremath{\eta} mesons emitted from the photoproduction off protons were measured for $0.70\ensuremath{\leqslant}{E}_{\ensuremath{\gamma}}\ensuremath{\leqslant}1.15$ GeV. The $\ensuremath{\gamma}p\ensuremath{\rightarrow}\ensuremath{\eta}p$ reaction process was separated $\ensuremath{\pi}\ensuremath{\eta}p$ final state by momentum difference of ${E}_{\ensuremath{\gamma}}\ensuremath{\geqslant}930$ MeV. angular distributions obtained and excitation function are essentially in good agreement...
Differential and total cross sections of the D(γ,η)pn reaction have been measured for photon energies between 600 1150 MeV. The data provide information γn →ηn above Eγ ≥ 800 section shows a narrow resonance structure peaked at = 1020 angular distribution coefficients together with are compared calculation isobar model by using impulse approximation. Although spin parity cannot be determined unambiguously, negative assignment gives better fit to data.
The recirculation loop of the Compact ERL (cERL) was constructed from July to November in 2013 after commissioning injector . Then entire cERL started December and beam could be accelerated up 20 MeV a short time recir culation ener gy recovery were also achieved without significant loss
A 6-m cryomodule including four Tesla-like cavities was developed, and tested in the Superconducting RF Test Facility phase-I at KEK. The performance as a total superconducting cavity system checked tests 2 K with high rf power. One of achieved stable pulsed operation $32\text{ }\text{ }\mathrm{MV}/\mathrm{m}$, which is higher than operating accelerating gradient ILC. maximum (${E}_{\mathrm{acc},\mathrm{max}}$) obtained vertical cw maintained or slightly improved pulse mode. Compensation...
The Japan Atomic Energy Research Institute (JAERI) is proposing a high intensity proton accelerator for the Neutron Science Project. A superconducting (SC) RF structure main option energy part of linac. Design and development work SC linac in progress JAERI. Three single-cell prototype cavities were fabricated their performances tested. test results good enough to apply This paper describes present status design
The microwave surface resistance of YBaCuO thick films was measured using a demountable copper cavity operated at 3 GHz in the TE 011 mode over temperature range from 4.2 K to 300 K. were deposited onto end plates and cylinder walls silver substrates or nickel-buffered by low-pressure plasma-spraying technique combined with melt-reaction method. area plate 177 cm 2 that wall 396 . obtained Q values before after substituting either for one covered film. ratio film lower than 0.08 5.2 0.65...
