Multijet production at low x<sub>Bj</sub> in deep inelastic scattering at HERA
ZEUS Collaboration,Chekanov, S.,Derrick, M.,Magill, S.,Musgrave, B.,Nicholass, D.,Repond, J.,Yoshida, R.,Mattingly, M.C.K.,Jechow, M.,Pavel, N.,Yagues Molina, A.G.,Antonelli, S.,Antonioli, P.,Bari, G. North Holland 2007 Nuclear Physics, Section B Vol.786 No.1
Inclusive dijet and trijet production in deep inelastic ep scattering has been measured for 10<Q<SUP>2</SUP><100 GeV<SUP>2</SUP> and low Bjorken x, 10<SUP>-4</SUP><x<SUB>Bj</SUB><10<SUP>-2</SUP>. The data were taken at the HERA ep collider with centre-of-mass energy s=318 GeV using the ZEUS detector and correspond to an integrated luminosity of 82 pb<SUP>-1</SUP>. Jets were identified in the hadronic centre-of-mass (HCM) frame using the k<SUB>T</SUB> cluster algorithm in the longitudinally invariant inclusive mode. Measurements of dijet and trijet differential cross sections are presented as functions of Q<SUP>2</SUP>, x<SUB>Bj</SUB>, jet transverse energy, and jet pseudorapidity. As a further examination of low-x<SUB>Bj</SUB> dynamics, multi-differential cross sections as functions of the jet correlations in transverse momenta, azimuthal angles, and pseudorapidity are also presented. Calculations at O(α<SUB>s</SUB><SUP>3</SUP>) generally describe the trijet data well and improve the description of the dijet data compared to the calculation at O(α<SUB>s</SUB><SUP>2</SUP>).
LARGE FORMAT CCD CAMERA FOR THE KISO 105 cm SCHMIDT TELESCOPE
YOSHIDA S.,AOKI T.,SOYANO T.,TARUSAWA K.,HASEGAWA T. The Korean Astronomical Society 1996 Journal of The Korean Astronomical Society Vol.29 No.suppl1
A new CCD camera equipped with a large format chip is now under construction for the Kiso 105-cm Schmidt telescope. We use SITe TK2048E, of which pixel size is 24 ${\mu}m$ and chip size is 48 mm square. TK2048E is thinned back-illuminated so that it has high sensitivity in U-band. The chip is cooled by a refrigerator instead of liquid nitrogen. MESSIA III is used as CCD control system.
Analysis of near weld stress field based on strain measurement and physical mesomechanics
Yoshida, S.,Sasaki, T.,Usui, M.,Park, I. K. Springer Science + Business Media 2016 Physical mesomechanics Vol.19 No.1
<P>Stresses induced by welding are analyzed from the viewpoint of material deformation behavior. Strain gages are used to measure the residual stresses, and electronic speckle-pattern interferometry is used to analyze the response of the welded work to external force. A tensile load is applied to a butt-welded, thin-plate steel specimen, and the resultant strain field is analyzed with the electronic speckle-pattern interferometry. Comparison is made with the case of a nonwelded specimen of the same material and dimension. The analysis indicates that the residual stress due to welding makes the normal strain due to the external tensile load asymmetric. The asymmetry enhances shear and rotational modes of deformation, generating stress concentration at a point away from the weld where the residual stress is substantially negligible. The observed features are discussed based on physical mesomechanics. Analysis reveals plastic deformation like behavior in the response of the welded specimen to the external force.</P>
Development of the readout system for the K2K SciBar detector
Yoshida, M.,Yamamoto, S.,Murakami, T.,Tanaka, M.,Nakaya, T.,Nishikawa, K.,Joo, K.K.,Kim, B.J.,Kim, J.Y.,Kim, S.B.,Lee, M.J.,Lim, I.T. IEEE 2004 IEEE transactions on nuclear science Vol.51 No.6
Readout electronics for the scintillation bar tracking detector (SciBar) in the K2K neutrino oscillation experiment has been developed. SciBar has 14 336 scintillator bars in total. The deposited energy and timing of particles from neutrino interactions in the scintillator bars are measured by 64-channel multianode photo-multiplier tubes (MAPMTs). Compact custom-designed electronics to record the MAPMT signals were developed, consisting of front-end circuit boards attached to each MAPMT and back-end electronics modules sitting in a VME crate. The front-end circuit board multiplexes pulse-height information from all 64 anodes and generates a fast triggering signal. Two sets of ASICs (IDEAS VA32HDR11 and TA32CG) are employed for these functions. The bias voltages and relay of control signals are also handled on the board. The back-end electronics module controls the front-end board by providing the control, timing, and low-voltage signals. The board also digitizes the multiplexed signal from the front-end. The electronics achieves low noise of less than 0.3 photo-electrons and good linearity up to 300 (150) photo-electrons for MAPMTs at the gain of 5×10<SUP>5</SUP> (10<SUP>6</SUP>).
