The Belle detector at the KEKB electron-positron collider has collected almost 1 billion Y(4S) events in its decade of operation. Super-KEKB, an upgrade is under construction, to increase luminosity by two orders magnitude during a three-year shutdown, with ultimate goal 8E35 /cm^2 /s luminosity. To exploit increased luminosity, been proposed. A new international collaboration Belle-II, being formed. Technical Design Report presents physics motivation, basic methods accelerator upgrade, as...
The backward angle anomaly (BAA) is investigated at Eα = 20∼25 MeV from the viewpoint of alpha-cluster structure high excited energies in 20Ne. orthogonality condition model adopted with use interaction potential derived a two-body which has starting-energy dependence. Both angular distributions and excitation function an extreme back are fairly well reproduced by model. It revealed that BAA caused essentially broad resonant surface partial waves correspond to well-developed states...
Fabrication of the central solenoid for ATLAS detector in CERN-LHC project was completed, and performance test has been successfully carried out Japan. The arrived at CERN to be assembled with LAr calorimeter. This paper describes fabrication mechanical, solenoid.
A 2 tesla, 7730 ampere, 39 MJ, 45 mm thin superconducting solenoid with a 2.3 meters warm bore and 5.3 length, is installed in the center of ATLAS detector successfully commissioned. The shares its cryostat one detector's calorimeters provides magnetic field required for inner detectors to accurately track collision products from LHC at CERN. After several years stepwise construction test program, integration 100 underground cavern completed. Following on-surface acceptance test, now...
A prototype thin superconducting solenoid magnet has been developed to verify technical feasibility of an advanced with a magnetic field 2 T in cylindrical volume 3.4 m /spl phi//spl times/9 and transparency 1.2 radiation length (Xo). The is required have stored energy/effective cold mass (E/M) ratio 7.5 kJ/kg. goal successfully achieved realizing E/M=9.6 kJ/kg as result the R&D. development test results are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML"...
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
Fabrication of the ATLAS central solenoid was completed and performance test has been carried out. The successfully charged up to 8.4 kA, which is 10% higher than normal operational current 7.6 kA. Two methods for quench protection, pure aluminum strips accelerating propagation protection heaters distributing zones, are applied in order safely dissipate stored energy. In this paper, characteristics described.
The ATLAS detector is presently under construction as one of the five LHC experiment set-ups. It relies on a sophisticated magnet system for momentum measurement charged particle tracks. superconducting solenoid at center detector, part nearest to proton-proton collision point. designed 2 Tesla strong axial magnetic field point, while its thin-walled 0.66 radiation lengths avoids degradation energy measurements in outer calorimeters. and calorimeter have been integrated their common...
A large superconducting solenoid magnet with an inner warm bore of 3.4 m in diameter and 4.1 length has been developed for the BELLE particle detector, which is installed KEKB colliding beam ring. The was into iron structure. cooled down by using a computer-controlled cooling system successfully energized up to design field 1.5 T no training quenches.
A sector-type superconducting spectrometer magnet, called SKS, for nuclear physics experiments in the 1-GeV/c region has been constructed and installed at KEK. It a maximum central magnetic field of 3 T magnet gap 50 cm, required by properties high resolution large acceptance. From another requirement to be movable around target cold state, flexible transfer line is adopted. The rated current 500 selected make heat losses as small possible. refrigerator used thermal insulations 80 20 K...
The ATLAS detector for the LHC at CERN requires a superconducting solenoid, which provides magnetic field inner detector. central solenoid and its associated proximity cryogenics system has been designed by KEK in collaboration with CERN. Following construction preliminary tests Toshiba Japan equipment shipped to is being prepared integration common cryostat LAr calorimeter, whereafter full on-surface test be completed before final installation 100 m underground cavern. For this purpose...
A capture cavity cryomodule was fabricated and used in a beam line for quantum experiments at the Superconducting RF Test Facility (STF) of High Energy Accelerator Research Organization Japan. The is about 4 m long contains two nine-cell cavities. cross section almost same as that STF cryomodules were to develop superconducting cavities International Linear Collider. An attempt made reduce large deflection helium gas return pipe (GRP) observed during cool-down warm-up. This paper briefly...
