The polarized double cell target of the SMC / NA47 Collaboration
The polarized target of the Spin Muon Collaboration at CERN was used for deep inelastic muon scattering experiments during 1993 to 1996 with a polarized muon beam to investigate the spin structure of the nucleon. Most of the experiments were carried out with longitudinal target polarization and 190 GeV muons, and some were done with transverse polarization and 100 GeV muons. [...]

A large streamer chamber muon tracking detector in a high-flux fixed-target application / NA47 Collaboration
Arrays of limited streamer tubes of the Iarocci type were deployed in our experiment at CERN as part of a forward muon detector system with provisions for the beam to pass through the center of each panel in the array. A total of sixteen 4 m x 4 m panels were assembled with inductive readout strips on both sides of each panel. [...]

The spin-dependent structure function $g_1(x)$ of the proton from polarized deep-inelastic muon scattering / NA47 Collaboration
We present a new measurement of the virtual photon proton asymmetry $A_1^{\rm p}$ from deep inelastic scattering of polarized muons on polarized protons in the kinematic range $0.0008 < x < 0.7$ and $0.2 < Q^{2} < 100$ GeV$^{2}$. With this, the statistical uncertainty of our measurement has improved by a factor of $2$ compared to our previous measurements. [...]

Measurement of proton and nitrogen polarization in ammonia and a test of equal spin temperature / NA47 Collaboration
The 1996 data taking of the SMC experiment used polarized protons to measure the spin dependent structure function $g_1$ of the proton. Three liters of solid granular ammonia were irradiated at the Bonn electron linac in order to create the paramagnetic radicals which are needed for polarizing the protons. [...]

Measurement of the SMC muon beam polarisation using the asymmetry in the elastic scattering off polarised electrons / NA47 Collaboration
A muon beam polarimeter was built for the SMC experiment at the CERN SPS, for beam energies of 100 and 190 GeV. The beam polarisation is determined from the asymmetry in the elastic scattering off the polarised electrons of a ferromagnetic target whose magnetisation is periodically reversed. [...]

A next-to-leading order QCD analysis of the spin structure function $g_1$ / Spin Muon Collaboration
We present a next-to-leading order QCD analysis of the presently available data on the spin structure function $g_1$ including the final data from the Spin Muon Collaboration (SMC). We present resu lts for the first moments of the proton, deuteron and neutron structure functions, and determine singlet and non-singlet parton distributions in two factorization schemes. [...]

The SMC polarized target / Kyynäräinen, J /NA47 Collaboration
The Spin Muon Collaboration (SMC) at CERN uses the largest solid polarized target in operation to measure the spin-dependent structure functions of the nucleons. The target is made of butanol, doped with EHBA-Cr(V), and has a volume of $2 \times 1280$ cm$^{3}$. [...]

Spin asymmetries $A_1$ and structure functions $g_1$ of the proton and the deuteron from polarized high energy muon scattering / NA47 Collaboration
We present the final results of the spin asymmetries $A_1$ and the spin structure functions $g_1$ of the proton and the deuteron in the kinematic range $0.0008<x<0.7$ and $0.2<Q^2<100$ GeV$^2$. For the determination of $A_1$, in addition to the usual method which employs inclusive scattering events and includes a large radiative background at low $x$, we use a new method which minimizes t he radiative background by selecting events with at least one hadron as well as a muon in the final state.

Dilution refrigerator for COMPASS polarized target / Berglund, P ; Gehring, R ; Koivuniemi, J H ; Kyynäräinen, J ; Takabayashi, N
A new experiment common muon and proton apparatus for structure and spectroscopy (COMPASS), on the spin structure of a nucleon is being prepared at CERN. The main goal of the muon programme is to measure the gluon contribution Delta G/G to the nucleon spin. [...]
