Supercapacitive Admittance Tomoscopy

Hubert Girault, Jean-Pierre Abid

A sensor for measuring adsorption on a substrate has been designed including a contactless detection scheme, called supercapacitive admittance tomoscopy (SCAT). The sensor comprises a thin dielectric layer with two parallel band electrodes on the one side ...

Measurement of the running of the electromagnetic coupling at large momentum-transfer at LEP

Qian Wang, Zhirui Xu, Aurelio Bay, Liang Sun, Horst Arthur Vogel, Jian Zhao, Eduardo Sanchez

The evolution of the electromagnetic coupling, α, in the momentum-transfer range 1800 GeV2 < -Q2 < 21600 GeV2 is studied with about 40 000 Bhabha-scattering events collected with the L3 detector at LEP at centre-of-mass energies √s = 189-209 GeV. The runni ...
