2.3.0 spase://CNES/NumericalData/CDPP-AMDA/PSP/epiHi/psp-let1-1hr LET1 1h Low Energy Telescope 1, 1h rate 2019-11-12T10:48:29Z LET1 and LET2 are similar in design to the HET, cylinders containing a central stack of detector disks and positionally sensitive detectors at the ends. LET1 has 1000-micron thick detector disks in the central stack, except for the end disks which are 500 microns. At the front of the cylinder, separate from the central stack, is a 12 micron thick disk and then a 25 micron disk. The back of the detector has the same arrangement. The front of the detector also has a thin window (~3 micron silicon equivalent). The 12, 25, and 500 micron thick disks are all separated into five active elements in the same way as the HET for positional determination. The Low-Energy Telescopes can measure protons and heavy ions from approximately 1 MeV to greater than 20 MeV/n and electrons from about 0.5 MeV to 2 MeV. The measurements are divided into two different sides of the instrument, A and B Please acknowledge the National Aeronautics and Space Administration, NASA spase://SMWG/Person/David.J.McComas PrincipalInvestigator spase://SMWG/Person/Eric.R.Christian DeputyPI PSP/ISoIS Energetic Particle Data - User Guide https://spdf.sci.gsfc.nasa.gov/pub/data/psp/isois/ISOIS_Data_Glossary.pdf Parker Solar Probe Mission Instrument web page, JPL http://parkersolarprobe.jhuapl.edu/Spacecraft/index.php#Instruments spase://SMWG/Repository/CNES/CDPP-AMDA Online Open AMDA at CDPP http://amda.cdpp.eu Text AMDA is a science analysis system provided by the Centre de Donnees de la Physique des Plasmas (CDPP) supported by CNRS, CNES, Observatoire de Paris and Universite Paul Sabatier, Toulouse SPDF Please acknowledge the CDAWeb team at GSFC/SPDF. spase://CNES/Instrument/CDPP-AMDA/PSP/epiHi EnergeticParticles 2018-09-02T00:00:12Z 2025-08-12T23:59:55Z PT3600S Heliosphere.Inner Sun.Corona h+ flux side A psp_let1_1h_AHf Proton flux side A 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux h+ A uncertainty psp_let1_1h_AHfu Proton flux side A uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux h+ flux side B psp_let1_1h_BHf Proton flux side B 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux h+ B uncertainty psp_let1_1h_BHfu Proton flux side B uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he flux side A psp_let1_1h_AHef Helium flux side A 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he A uncertainty psp_let1_1h_AHefu Helium flux side A uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he flux side B psp_let1_1h_BHef Helium flux side B 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he B uncertainty psp_let1_1h_BHefu Helium flux side B uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux h+ rate side A psp_let1_1h_AHr proton rate side A counts/s Spectrogram CountRate h+ rate side B psp_let1_1h_BHr proton rate side B counts/s Spectrogram CountRate he rate side A psp_let1_1h_AHer Helium rate side A counts/s Spectrogram CountRate he rate side B psp_let1_1h_BHer Helium rate side B counts/s Spectrogram CountRate si rate side A psp_let1_1h_ASir Silicon rate side A counts/s Spectrogram CountRate si rate side B psp_let1_1h_BSir Silicon rate side B counts/s Spectrogram CountRate c rate side A psp_let1_1h_ACr Carbon rate side A counts/s Spectrogram CountRate c rate side B psp_let1_1h_BCr Carbon rate side B counts/s Spectrogram CountRate n rate side A psp_let1_1h_ANr Nitrogen rate side A counts/s Spectrogram CountRate n rate side B psp_let1_1h_BNr Nitrogen rate side B counts/s Spectrogram CountRate ne rate side A psp_let1_1h_ANer Neon rate side A counts/s Spectrogram CountRate ne rate side B psp_let1_1h_BNer Neon rate side B counts/s Spectrogram CountRate s rate side A psp_let1_1h_ASr Sulfur rate side A counts/s Spectrogram CountRate s rate side B psp_let1_1h_BSr Sulfur rate side B counts/s Spectrogram CountRate fe rate side A psp_let1_1h_AFer Iron rate side A counts/s Spectrogram CountRate fe rate side B psp_let1_1h_BFer Iron rate side B counts/s Spectrogram CountRate cr rate side A psp_let1_1h_ACrr Chromium rate side A counts/s Spectrogram CountRate cr rate side B psp_let1_1h_BCrr Chromium rate side B counts/s Spectrogram CountRate o rate side A psp_let1_1h_AOr Oxygen rate side A counts/s Spectrogram CountRate o rate side B psp_let1_1h_BOr Oxygen rate side B counts/s Spectrogram CountRate ni rate side A psp_let1_1h_ANir Nickel rate side A counts/s Spectrogram CountRate ni rate side B psp_let1_1h_BNir Nickel rate side B counts/s Spectrogram CountRate ca rate side A psp_let1_1h_ACar Calcium rate side A counts/s Spectrogram CountRate ca rate side B psp_let1_1h_BCar Calcium rate side B counts/s Spectrogram CountRate al rate side A psp_let1_1h_AAlr Aluminium rate side A counts/s Spectrogram CountRate al rate side B psp_let1_1h_BAlr Aluminium rate side B counts/s Spectrogram CountRate mg rate side A psp_let1_1h_AMgr Magnesium rate side A counts/s Spectrogram CountRate mg rate side B psp_let1_1h_BMgr Magnesium rate side B counts/s Spectrogram CountRate ar rate side A psp_let1_1h_AArr Argon rate side A counts/s Spectrogram CountRate ar rate side B psp_let1_1h_BArr Argon rate side B counts/s Spectrogram CountRate na rate side A psp_let1_1h_ANar Sodium rate side A counts/s Spectrogram CountRate na rate side B psp_let1_1h_BNar Sodium rate side B counts/s Spectrogram CountRate
