In light-emitting electrochemical cells (LECs), the position of the emission zone (EZ) is not predefined via a multilayer architecture design, but governed by a complex motion of electrical and ionic charges. As a result of the evolution of doped charge tr ...

Runaway electron beam stability and decay in COMPASS

Karin Söderström, Joan Decker, Gergely Papp

This paper presents two scenarios used for generation of a runaway electron (RE) beam in the COMPASS tokamak with a focus on the decay phase and control of the beam. The first scenario consists of massive gas injection of argon into the current ramp-up pha ...

Search for Omega(2012) -> K Xi(1530) -> K pi Xi at Belle

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Ke Huang, Donghyun Kim, Lei Li

Using data samples of e(+)e(-) collisions collected at the Upsilon(1S), Upsilon(2S), and Upsilon(3S) resonances with the Belle detector, we search for the three-body decay of the Omega(2012) baryon to K pi Xi. This decay is predicted to dominate for models ...

Development and validation of a double focalizing magnetic spectrometer for beta spectrum measurements

Guido Haefeli, François Bochud

In the framework of the EMPIR project MetroBeta, the development and optimization of a double focalizing magnetic spectrometer have been realized in order to measure the beta spectra shape. The acquisition is designed to perform, after focalization by the ...

First measurements of absolute branching fractions of the Xi(+)(c) baryon at Belle

Olivier Schneider, Yiming Li, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Donghyun Kim, Lei Li

We present the first measurements of the absolute branching fractions of Xi(+)(c) decays into Xi(-)pi(+)pi(+) and pK(-)pi(+) final states. Our analysis is based on a data set of (772 +/- 11) x 10(6) B (B) over bar pairs collected at the Upsilon(4S) resonan ...
