Studying and applying magnetic dressing with a Bell and Bloom magnetometer
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
The magnetic dressing phenomenon occurs when spins precessing in a static field (holding field) are subject to an additional, strong, alternating field. It is usually studied when…
Restoring Narrow Linewidth to a Gradient-Broadened Magnetic Resonance by Inhomogeneous Dressing
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
We study the possibility of counteracting the line-broadening of atomic magnetic resonances due to inhomogeneities of the static magnetic field by means of spatially dependent magn…
Atomic orientation by a broadly frequency-modulated radiation: theory and experiment
G. Bevilacqua, V. Biancalana, Y. Dancheva
We investigate magnetic resonances driven in thermal vapour of alkali atoms by laser radiation broadly modulated at a frequency resonant with the Zeeman splitting. A model accounti…
Measurement of XeI and XeII velocity in the near exit plane of a low-power Hall effect thruster by light induced fluorescence spectroscopy
Y. Dancheva, V. Biancalana, D. Pagano +1
Near exit plane non-resonant light induced fluorescence spectroscopy is performed in a Hall effect low-power Xenon thruster at discharge voltage of 250V and anode flow rate of 0.7m…
Larmor frequency dressing by an anharmonic transverse magnetic field
G. Bevilacqua, V. Biancalana, Y. Dancheva +1
We present a theoretical and experimental study of spin precession in the presence of both a static and an orthogonal oscillating magnetic field, which is nonresonant, not harmonic…
All-optical magnetometry for NMR detection in a micro-Tesla field and unshielded environment
Giuseppe Bevilacqua, Valerio Biancalana, Yordanka Dancheva +1
An all-optical atomic magnetometer is used to detect a proton free-precession signal from a water sample polarized in a 0.7 T field and remotely analyzed in a 4 field. Nuclear…
Dual channel self-oscillating optical magnetometer
J. Belfi, G. Bevilacqua, V. Biancalana +4
We report on a two-channel magnetometer based on nonlinear magneto-optical rotation in a Cs glass cell with buffer gas. The Cs atoms are optically pumped and probed by free running…
All optical sensor for automated magnetometry based on Coherent Population Trapping
J. Belfi, G. Bevilacqua, V. Biancalana +2
An automated magnetometer suitable for long lasting measurement under stable and controllable experimental conditions has been implemented. The device is based on Coherent Populati…
