The Energetic Particle Detector (EPD) Investigation is one of five particles and fields investigations on the Magnetospheric Multiscale (MMS) mission. This mission consists four satellites operating in close proximity elliptical, low-inclination orbits, focused upon fundamental physics magnetic reconnection. investigation aboard MMS spacecraft two instrument designs, EIS (Energetic Ion Spectrometer) FEEPS (Fly’s Eye Electron Proton Spectrometer). present paper describes from an engineering...
The Relativistic Proton Spectrometer (RPS) on the Radiation Belt Storm Probes spacecraft is a particle spectrometer designed to measure flux, angular distribution, and energy spectrum of protons from ∼60 MeV ∼2000 MeV. RPS will investigate decades-old questions about inner Van Allen belt proton environment: nearby region space that relatively unexplored because hazards operation there difficulties in obtaining accurate measurements an intense penetrating background. provide accuracy needed...
The quality control of thin film thickness measurements through the transmission and counting beta X-ray radiation has achieved very competitive precision with values to 0.2%. However, when attenuated intensities by under measurement is above 90%, method or generates a dramatic degradation in 30%. This work presents new obtain analyze thicknesses aluminum copper films using energy distribution information provided triple gas electron multiplier detector (3GEM). based on ratio peak Landau...
Abstract A growing number of experiments with particle detectors using liquid argon are currently being carried out, as this is an excellent means detecting neutrinos. These develop different capture and measurement systems the photons generated by excitation atoms when a charged passes. New low-cost technologies, more sensitive efficient detection methods, hardware electronics, optimize take advantage characteristics processes involved. This minireview presents main photodetection used in...
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...
The Scalable Readout System (SRS) of the RD51 collaboration with APV25 ASIC is driving research and development for gaseous detectors. Discontinuation demands on flexibility concerninge.g. detector capacitance readout rate induced a replacement ASIC, which col-laboration has chosen VMM chip ATLAS New Small Wheel upgrade. A prototype SRSVMM system was operated small GEM detectors at test beams hardware componentsare finalised. More than twelve groups signed as primary users. We present...
Abstract In this work, a process for the assembly of standard triple Gas Electron Multiplier detector and study main variables was made at Universidad Antonio Nariño, Colombia, detectors laboratory. The gas electron multiplier tested with Ar/CO 2 mixtures in proportions 70/30%, 80/20% 90/10% using 55 Fe X-ray source (5.9 keV). energy spectrum, resolution, effective gain ionization rate were analyzed according to applied voltage mixture. obtained an resolution up 19% close 10 4 ; where...
This paper presents the performance of a 3GEM in terms identification high and low beta energy radiation sources through distribution main used for industrial application 90Sr 204Tl. We compare theoretical loss into drift zone with experimental at different voltages. The results show that Most Probable Value (MPV) fitted Landau obtained from 204Tl degree error lower than 14% comparison to calculation. Additionally, source (90Sr) is identified (204Tl) - taking account MPV sigma values...
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...
The energy deposited by the laser pulse on critical surface of plasma is transmitted thermal conduction through supercritical layer corona, producing ablation pellet's surface. This preferentially transferred to electrons, which collisions, transmit it other electrons. It has been experimentally observed, and scientifically demonstrated that there are magnetic fields generated spontaneously implosion pellets in plasmas produced inertial confmement.This work attempts study reduction...
