Measurements of charged pion differential yields from the surface of the T2K replica target for incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPS / The NA61 collaboration
Measurements of particle emission from a replica of the T2K 90 cm-long carbon target were performed in the NA61/SHINE experiment at CERN SPS, using data collected during a high-statistics run in 2009. An efficient use of the long-target measurements for neutrino flux predictions in T2K requires dedicated reconstruction and analysis techniques [...]

Measurements of $\pi ^{\pm }$ , $K^{\pm }$ , $K^0_S$ , $\varLambda $ and proton production in proton–carbon interactions at 31 GeV/c with the NA61/SHINE spectrometer at the CERN SPS / NA61/SHINE Collaboration
Measurements of hadron production in p+C interactions at 31 GeV/c are performed using the NA61/ SHINE spectrometer at the CERN SPS. The analysis is based on the full set of data collected in 2009 using a graphite target with a thickness of 4% of a nuclear interaction length. [...]

Design and Performance of the Data Acquisition System for the NA61/SHINE Experiment at CERN / Laszlo, Andras (Wigner RCP, Budapest) ; Denes, Ervin (Wigner RCP, Budapest) ; Fodor, Zoltan (Wigner RCP, Budapest) ; Kiss, Tivadar (Wigner RCP, Budapest) ; Kleinfelder, Stuart (UV, Irvine) ; Soos, Csaba (CERN) ; Tefelski, Dariusz (Warsaw U. of Tech.) ; Tolyhi, Tamas (Wigner RCP, Budapest) ; Vesztergombi, Gyorgy (Wigner RCP, Budapest) ; Wyszynski, Oskar (Jagiellonian U. ; CERN)
This paper describes the hardware, firmware and software systems used in data acquisition for the NA61/SHINE experiment at the CERN SPS accelerator. Special emphasis is given to the design parameters of the readout electronics for the 40 m^3 volume Time Projection Chamber detectors as these give the largest contribution to event data among all the subdetectors: events consisting of 8 bit ADC values from 256 time slices of 200 k electronic channels are to be read out with order of ~100 Hz readout rate.

NA61/SHINE facility at the CERN SPS: beams and detector system / NA61 collaboration
NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a multi-purpose experimental facility to study hadron production in hadron-proton, hadron-nucleus and nucleus-nucleus collisions at the CERN Super Proton Synchrotron. It recorded the first physics data with hadron beams in 2009 and with ion beams (secondary 7Be beams) in 2011. [...]

Measurement of negatively charged pion spectra in inelastic p+p interactions at $p_{lab}$ = 20, 31, 40, 80 and 158 GeV/c / NA61/SHINE Collaboration
We present experimental results on inclusive spectra and mean multiplicities of negatively charged pions produced in inelastic p+p interactions at incident projectile momenta of 20, 31, 40, 80 and 158GeV/c ($\sqrt{s}$ = 6.3, 7.7, 8.8, 12.3 and 17.3GeV, respectively). The measurements were performed using the large acceptance NA61/SHINE hadron spectrometer at the CERN super proton synchrotron. [...]

Pion emission from the T2K replica target: method, results and application / NA61/SHINE Collaboration
The T2K long-baseline neutrino oscillation experiment in Japan needs precise predictions of the initial neutrino flux. The highest precision can be reached based on detailed measurements of hadron emission from the same target as used by T2K exposed to a proton beam of the same kinetic energy of 30 GeV. [...]
