(JAEA, Ibaraki) et al.
Detailed $\gamma$-ray spectroscopy of the exotic neon isotope $^{28}$Ne has been performed for the first time using the one-neutron removal reaction from $^{29}$Ne on a liquid hydrogen target at 240~MeV/nucleon. Based on an analysis of parallel momentum distributions, a level scheme with spin-parity assignments has been constructed for $^{28}$Ne and the negative-parity states are identified for the first time.

/ Takeuchi, Yusuke (Kyushu U.) ; Cicek, Ersin (KEK, Tsukuba) ; Ego, Hiroyasu (KEK, Tsukuba) ; Futatsukawa, Kenta (KEK, Tsukuba) ; Iwashita, Yoshihisa (Kyoto U., KURRI) ; Kawamura, Naritoshi (KEK, Tsukuba) ; Kitamura, Ryo (JAEA, Ibaraki) ; Kondo, Yasuhiro (J-PARC) ; Mibe, Tsutomu (KEK, Tsukuba) ; Morishita, Takatoshi (J-PARC) et al.
The muon g-2/EDM experiment is under preparation at Japan Proton Accelerator Research Complex (J-PARC), and the muon linear accelerator for the experiment is being developed. A Disk-and-Washer (DAW) cavity will be used for the medium-velocity part of the accelerator, and muons will be accelerated from v/c=ß=0.3 to 0.7 with the operating frequency of 1.296 GHz. [...]

Design and Beam Dynamics Study of Disk-Loaded Structure for Muon Linac
/ Sumi, Kazumichi (Nagoya U.) ; Ego, Hiroyasu (KEK, Tsukuba) ; Iijima, Toru (Nagoya U.) ; Inami, Kenji (Nagoya U.) ; Kondo, Yasuhiro (J-PARC) ; Mibe, Tsutomu (KEK, Tsukuba) ; Moriya, Katsuhiro (JAEA, Ibaraki) ; Nakazawa, Yuga (Ibaraki U., Mito) ; Otani, Masashi (J-PARC) ; Saito, Naohito (KEK, Tsukuba) et al.
The disk-loaded structures (DLS) in the muon LINAC are under development for the J-PARC muon g-2/EDM experiment. Four DLSs with an accelerating gradient of 20 MV/m take charge of muon acceleration from 40 MeV to 212 MeV, which corresponds to 70% to 94% of the speed of light. [...]

Isotopic production cross sections of residual nuclei in proton-and deuteron-induced reactions on $^{91,92}$Y,$^{92,93}$Zr,and$^{93,94}$Nb around 100 MeV/nucleon
/ Watanabe, Yu (Kyushu U., Kasuga) ; Suwa, J (Kyushu U., Kasuga ; Nishina Ctr., RIKEN) ; Nakano, K (Kyushu U., Kasuga ; Wako, RIKEN) ; Kawase, S (Kyushu U., Kasuga) ; Wang, H (Wako, RIKEN) ; Otsu, H (Wako, RIKEN) ; Sakurai, H (Wako, RIKEN) ; Ahn, D S (Wako, RIKEN) ; Aikawa, M (Hokkaido U.) ; Ando, T (Tokyo U.) et al.
Production cross sections of residual nuclei via proton-and deuteron-induced spallation reactions on 91,92 Y, 92,93 Zr, and 93,94 Nb at projectile energies Production cross sections of residual nuclei via proton-and deuteron-induced spallation reactions on $^{91,92}$Y,$^{92,93}$Zr,and $^{93,94}$Nb at projectile energies around 100 MeV/nucleon were measured in inverse kinematics at the RIKEN Radioactive Isotope Beam Factory. Noticeable jumps in the measured cross sections of isotone production appear between the neutron numbers N =51 and 50 for target nuclei with the initial neutron number N$_{init}$ =53 ($^{92}$Y, $^{93}$Zr, and $^{94}$Nb), while such jump is not clearly seen for target nuclei with N$^{init}$=52($^{91}$Y,$^{92}$Zr, and $^{93}$Nb).

A 2 tesla, 7730 ampere, 39 MJ, 45 mm thin superconducting solenoid with a 2.3 meters warm bore and 5.3 meters length, is installed in the center of the ATLAS detector and successfully commissioned. The solenoid shares its cryostat with one of the detector's calorimeters and provides the magnetic field required for the inner detectors to accurately track collision products from the LHC at CERN.
