Vacuum phototriodes for the CMS electromagnetic calorimeter endcap [PDF]

, 2004
The measurement of scintillation light from the lead tungstate crystals of the Compact Muon Solenoid (CMS) electromagnetic calorimeter (ECAL) poses a substantial technical challenge, particularly in the endcap regions, where the radiation levels are ...

Characterization of Power Transformer Electromagnetic Forces Affected by Winding Faults [PDF]

Journal of Operation and Automation in Power Engineering, 2018
Electromagnetic forces in power transformer windings are produced by interaction between the leakage fluxes and current passing them. Since the leakage flux distribution along the windings height is in two axial and radial directions, so the ...

Derivations of relativistic force transformation equations [PDF]

, 2011
The correct general form of relativistic transformation equations for the three-vector force is derived without using four-vectors, via the relativistic Newton's second law. The four-vector approach to the problem is also presented.
