Traceable instruments for encircled angular flux measurements
Natascia Castagna, Jacques Morel, Edward Robinson +1
We report on the development of an instrument for the measurement of the Encircled Angular Flux (EAF) and on establishing its metrological traceability at the required level of unc…
Modelling of standard and specialty fibre-based systems using finite element methods
Natascia Castagna, Jacques Morel, Luc Testa +1
We report on the investigation of an approach for modelling light transmission through systems consisting of several jointed optical fibres, in which the analytical modelling of th…
A room temperature 19-channel magnetic field mapping device for cardiac signals
G. Bison, N. Castagna, A. Hofer +5
We present a multichannel cardiac magnetic field imaging system built in Fribourg from optical double-resonance Cs vapor magnetometers. It consists of 25 individual sensors designe…
A large sample study of spin relaxation and magnetometric sensitivity of paraffin-coated Cs vapor cells
N. Castagna, G. Bison, G. Di Domenico +5
We have manufactured more than 250 nominally identical paraffin-coated Cs vapor cells (30 mm diameter bulbs) for multi-channel atomic magnetometer applications. We describe our ded…
On the stability of optical lattices
G. Di Domenico, N. Castagna, M. D. Plimmer +3
In this article, we present an analysis of the stability of optical lattices. Starting with the study of an unstable optical lattice, we establish a necessary and sufficient condit…
