Design, Commissioning and Performance of the PIBETA Detector at PSI

E. Frlez, D. Pocanic, K. A. Assamagan +41

We describe the design, construction and performance of the PIBETA detector built for the precise measurement of the branching ratio of pion beta decay, pi+ -> pi0 e+ nu, at the Pa…

Light response of pure CsI calorimeter crystals painted with wavelength-shifting lacquer

E. Frlez, Ch. Broennimann, B. Krause +6

We have measured scintillation properties of pure CsI crystals used in the shower calorimeter built for a precise determination of the pi+ -> pi0 e+ nu decay rate at the Paul Scher…

Flavor Decomposition of the Polarized Quark Distributions in the Nucleon from Inclusive and Semi-inclusive Deep-inelastic Scattering

K. Ackerstaff, The HERMES Collaboration

Spin asymmetries of semi-inclusive cross sections for the production of positively and negatively charged hadrons have been measured in deep-inelastic scattering of polarized posit…

Cosmic muon tomography of pure cesium iodide calorimeter crystals

E. Frlez, I. Supek, K. A. Assamagan +10

Scintillation properties of pure CsI crystals used in the shower calorimeter being built for precise determination of the pi+ -> pi0 e+ nu decay rate are reported. Seventy-four ind…

Determination of the Deep Inelastic Contribution to the Generalised Gerasimov-Drell-Hearn Integral for the Proton and Neutron

K. Ackerstaff

The virtual photon absorption cross section differences [sigma_1/2-sigma_3/2] for the proton and neutron have been determined from measurements of polarised cross section asymmetri…

The HERMES Back Drift Chambers

S. Bernreuther et al

The tracking system of the HERMES spectrometer behind the bending magnet consists of two pairs of large planar 6-plane drift chambers. The design and performance of these chambers…
