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 psp-isois-let1 PartOf LET1 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 PT60S Heliosphere.Inner Sun.Corona h+ flux side A psp_let1_1min_AHf Proton flux side A 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux h+ A uncertainty psp_let1_1min_AHfu Proton flux side A uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux h+ flux side B psp_let1_1min_BHf Proton flux side B 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux h+ B uncertainty psp_let1_1min_BHfu Proton flux side B uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he flux side A psp_let1_1min_AHef Helium flux side A 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he A uncertainty psp_let1_1min_AHefu Helium flux side A uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he flux side B psp_let1_1min_BHef Helium flux side B 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux he B uncertainty psp_let1_1min_BHefu Helium flux side B uncertainty 1/cm²/sr/s/(MeV/nuc) Spectrogram EnergyFlux
