The beam test facility at Jefferson Lab for the precise energy measurement of future calorimeter concepts
Vladimir V. Berdnikov, Alexander Somov
In experimental nuclear physics (NP), high-precision electromagnetic calorimetry typically requires a good energy resolution and linear photosensor response on the level of (1-2)%…
Installation and first commissioning results of the JEF lead tungstate calorimeter
Alexander Somov, Vladimir Berdnikov
The Electromagnetic Calorimeter (ECAL), consisting of 1,596 lead tungstate scintillating crystals, has been recently constructed and installed in Experimental Hall D at Jefferson L…
New Measurements of the Deuteron to Proton F2 Structure Function Ratio
Debaditya Biswas, Fernando Araiza Gonzalez, William Henry +89
Nucleon structure functions, as measured in lepton-nucleon scattering, have historically provided a critical observable in the study of partonic dynamics within the nucleon. Howeve…
