We have assembled a small-scale streaming data acquisition system based on the SAMPA front-end ASIC. We report on measurements performed on the SAMPA chip and preliminary cosmic ray data acquired from a Gas Electron Multiplier (GEM) detector read out using the SAMPA.

We have assembled a small-scale streaming data acquisition system based on the SAMPA front-end ASIC. The 32-channel SAMPA chip was designed for the high-luminosity upgrade of the ALICE Time Projection Chamber (TPC) detector at the CERN Large Hadron Collider. The goals of …

Structure functions, as measured in lepton-nucleon scattering, have proven to be very useful in studying the partonic dynamics within the nucleon. However, it is experimentally difficult to separately determine the longitudinal and transverse structure functions, and consequently there are substantially less data …

The Polarized Electrons for Polarized Positrons experiment at the injector of the Continuous Electron Beam Accelerator Facility has demonstrated for the first time the efficient transfer of polarization from electrons to positrons produced by the polarized bremsstrahlung radiation induced by a polarized …

Background: Measurements of forward exclusive meson production at different squared four-momenta of the exchanged virtual photon, ${Q}^{2}$, and at different four-momentum transfer, $t$, can be used to probe QCD's transition from meson-nucleon degrees of freedom at long distances to quark-gluon degrees of …

The study of exclusive ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}$ electroproduction on the nucleon, including separation of the various structure functions, is of interest for a number of reasons. The ratio ${R}_{L}={\ensuremath{\sigma}}_{L}^{{\ensuremath{\pi}}^{\ensuremath{-}}}/{\ensuremath{\sigma}}_{L}^{{\ensuremath{\pi}}^{+}}$ is sensitive to isoscalar contamination to the dominant isovector pion exchange amplitude, which is the …
