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 density, these turbulent seen as high-amplitude bursts, and, since last decade, a stochastic pulse train model (SPTM) has been developed to describe locally measured signals. The SPTM, which is also known filtered Poisson process, models plasma fluctuations superposition pulses...
The procedure to estimate the average local temperature, density, and plasma potential by conditionally selecting points of Langmuir probe characteristic curve is revised applied study intermittent bursts in Texas Helimak TCABR tokamak. improvements made allow us distinguish burst temperature from turbulent background propagation. Thus, Helimak, we identify important differences with respect measured top bottom regions machine. While region temperatures are almost equal background, hotter...
The effects of coherent structures in plasma edge turbulence are an important topic the study cross-field transport magnetically confined plasmas. To properly characterize these structures, their temperature must be measured, which is often done by using Langmuir probes. In this work, techniques sweep and triple probe used, considering effect sheath expansion both methods. It shown that if ignored, technique gives overestimated values. addition, conditional analysis applied to order evaluate...
Abstract Locating in space is essential for devices that perform navigation. currently inertial measurement units have been developed to allow navigation, however, this type of sensors present different errors measurements. They appear and accumulate when measurements advance. For reason, the characterization error sources presented sensor BNO055 performed; data acquired using a Raspberry Pi Allan’s variance method was used analysis. A parameter fit made equation Levenberg-Marquardt...

Abstract Silicon photomultipliers are devices widely used and have direct applications in multiple scientific fields. Currently, the Universidad Antonio Nariño, Colombia, finance research project Characterization of coherent structures edge region plasma column TCABR tokamak using Langmuir probes collaboration with Universidade de Sao Paulo, Brazil. In this project, we plasma, recently, proposed a silicon photomultiplier to measure X-ray emissions from column. application, know specific...
