“…The K 0 meson was inclusively measured via the π + π − decay channel using NKS, which was constructed and installed in the second experimental hall equipped with the STB-Tagger system [24] at LNS. NKS was originally used as the TAGX spectrometer at the electron synchrotron of the Institute of Nuclear Study, University of Tokyo (INS-ES) [25]. In this section, the apparatuses of the beam line and the detectors of NKS are described.…”

The photoproduction process of neutral kaons on a liquid deuterium target is investigated near the threshold region, Eγ = 0.8-1.1 GeV. K 0 events are reconstructed from positive and negative pions, and differential cross sections are derived. Experimental momentum spectra are compared with those calculated in the spectator model using a realistic deuteron wave function. Elementary amplitudes as given by recent isobar models and a simple phenomenological model are used to study the effect of the new data on the angular behavior of the elementary cross section. The data favor a backward-peaked angular distribution of the elementary n(γ, K 0 )Λ process, which provides additional constraints on current models of kaon photoproduction. The present study demonstrates that the n(γ, K 0 )Λ reaction can provide key information on the mechanism of the photoproduction of strangeness.

“…For better understanding of strangeness photoproduction, high statistic and accurate experimental data, especially for neutral channels, are necessary. The first observation of photoproduction of neutral kaon events by a magnetic spectrometer was successfully carried out using the TAGX spectrometer [4,5] at the 1.3 GeV electron synchrotron of the Institute for Nuclear Study, University of Tokyo. Neutral kaons were detected via the K 0 S → π + π − decay channel.…”

A large-acceptance spectrometer, Neutral Kaon Spectrometer 2 (NKS2), was newly constructed to explore various photoproduction reactions in the giga- * Corresponding author. electronvolt region at the Laboratory of Nuclear Science (LNS, currently ELPH), Tohoku University. The spectrometer consisted of a dipole magnet, drift chambers, and plastic scintillation counters. NKS2 was designed to separate pions and protons in a momentum range of less than 1 GeV/c, and was placed in a tagged photon beamline. A cryogenic H 2 /D 2 target fitted to the spectrometer were designed. The design and performance of the detectors are described. The results of the NKS2 experiment on analyzing strangeness photoproduction data using a 0.8-1.1 GeV tagged photon beam are also presented.
