We investigate the turbulence level dependence on plasma profiles in experiments in Texas Helimak, a toroidal basic plasma device, with long stable electron cyclotron resonant heating (ECRH) discharges and great flexibility to alter the equilibrium m

Blob-like filamentary structures are omnipresent in magnetized plasmas. Their transport deteriorates the particle confinement and may damage plasma-facing components of future fusion devices. In local measurements of density, these turbulent structur

The behavior of energetic particle driven modes in magnetically confined plasmas is an important issue for ITER, once these modes can affect the transport of the fast particles. This paper presents some data analysis methods suitable for dealing with

$^{229}\mathrm{Th}$ has an isomeric state of unusually low energy, whose adopted value is by now 3.5(10) eV. This value was determined indirectly, based on several very precise \ensuremath{\gamma}-ray energies, between 25 and 217 keV, from the $\ensu

Gamma‐ray and level energies of 229Th were reinvestigated using available experimental information and different assumptions regarding the decay scheme. We used in the fitting a statistical approach that takes into account both variances and covari

This paper presents a one step self-calibration procedure, based on the least squares method, to be used in gamma-ray energy measurements. The obtained equation allows a qualitative interpretation of the information provided by an experiment.

Shearless transport barriers appear in confined plasmas due to non-monotonic radial profiles and cause localized reduction of transport even after they have been broken. In this paper we summarize our recent theoretical and experimental research on s

When performed with a multi-detector system, γγ directional correlation measurements need to be corrected differently for each independent detector pair, especially when those detectors have different active volumes and subtend different solid angl
