STEREO-A PLasma and Supra-Thermal Ion Composition (PLASTIC) He++ Phase Space Densities and Counts in 6 normailzed Velocity Ranges and Proton Plasma Moments, Level 3 (L3), 1 h Data

This data set presents STEREO-A PLASTIC PickUp Ion, PUI, He⁺² phase space densities, PSD, in the spacecraft frame of reference. The data set provides 1 hr averages of He⁺², phase space density as a function of V/Vsw in 51 velocity ranges, where V and Vsw are the PUI particle speed and bulk speed of solar wind protons, respectively. These data are delivered to the public domain on a regular basis. Efforts are made to include the latest known calibration and background determinations, however, these are expected to undergo revision. We therefore suggest that users regularly return to this page, and make sure to get the most recent revision. If the STEREO PLASTIC data are used in presentations or publications, we strongly suggest that that the authors contact A.B. Galvin, STEREO PLASTIC PI, at toni.galvin@unh.edu and Dr. B. Klecker at berndt.klecker@mpe.mpg.de to ensure that the latest release of the data is utilized. Also, please acknowledge the STEREO PLASTIC Investigation, A.B. Galvin and NASA Grants NNX15AU01G and 80NSSC17K0556. For reporting purposes, we request bibliography information for any publication, etc., using these data. Please send information on the use of these data to A.B. Galvin. If you have questions regarding the data formats, please contact the STEREO PLASTIC Data System Manager: Lorna Ellis at lorna.ellis@unh.edu.

A FEEPS consists of six Heads, each composed of two Eyes. Each eye is a particle telescope with a single silicon detector. There are nine electron eyes and three ion eyes per FEEPS. The energy coverage is from 25 keV to 650 keV for electrons and 45 keV to 650 keV for ions. Each eye has sixteen energy channels, the spacing of which can be modified by command. The fields of view and pointing of each eye are designed to provide a broad, instantaneous field of view for the twelve eyes per FEEPS.

Response of human lymphoblastoid cells to HZE (iron ions) or gamma-rays

Transcriptional profiling of human lymphoblastoid TK6 cells comparing mock irradiated cells with cells exposed 24 hours previously to 1.67 Gy HZE (1 GeV/amu iron ions accelerated at the NASA Space Research Laboratory (NSRL) of Brookhaven National Laboratory) or 2.5 Gy 137Cs gamma rays. TK6 cells were mock irradiated or exposed to HZE or gamma-rays, and RNA was harvested 24 hours later. 3 biological replicates were independently grown and harvested during three different runs at the NSRL. One replicate per array.

ACE Solar Wind Ion Composition Spectrometer (SWICS) Solar Wind Plasma Elemental Charge State Distributions with Statistical Uncertainties and Data Quality Flags, Level 2 (L2), 2 h Data

This ACE SWICS/SWIMS Data Set contains actual Charge State, Q, Distributions of Carbon, Oxygen, Neon, Magnesium, Silicon and Iron as opposed to the averaged Charge States that have been available on CDAWeb for some time. The Solar Wind Ion Composition Spectrometer (SWICS), prior to August 23, 2011 and denoted as SWICS Version 1.1, determines uniquely the Chemical and Ionic Charge State Composition of the Solar Wind, the Temperatures and Mean Speeds of major Solar Wind Ions at all Speeds above 300 km/s for Protons and 170 km/s for Fe+16, and resolves Protons and Helium Isotopes of Solar and Interstellar Sources. SWICS 1.1 measures the Distribution Functions of Interstellar Cloud Pick-Up Ions and Interplanetary Dust Cloud Pick-Up Ions up to Energies of 100 keV/e. The ACE SWICS 1.1 Data Products represent a new Release of the Data with significantly improved Time Series Measurements for the Elemental Abundance, Charge State Composition, and Kinetic Properties of Heavy Ions in the Solar Wind. It is a major new Update produced with completely redesigned Analysis Methods to account more rigorously for Instrumental and Statistical Effects (Shearer et al., 2014). Rare Elements are now identified more reliably and Estimates of Statistical Error are provided. Release Notes are available that describe the Data, the Methods used to determine the Data Values, and Issues concerning Data Quality and Measurement Uncertainty. The Quality of ACE Level 2 Data is such that it is suitable for serious Scientific Study. However, to avoid Confusion and Misunderstanding, it is recommended that Users consult with the appropriate ACE Team Members before publishing Work derived from the Data. The ACE Team has worked hard to ensure that the Level 2 Data are free from Errors, but the Team cannot accept Responsibility for Erroneous Data, or for Misunderstandings about how the Data may be used. This is especially true if the appropriate ACE Team Members are not consulted before Publication. At the very least, Preprints should be forwarded to the ACE Team before Publication.

MMS 3 Fast Plasma Investigation, Dual Ion Spectrometer (FPI, DIS) Instrument Distributions, Level 2 (L2), Burst Mode, 0.15 s Data

The Fast Plasma Instrument (FPI) usually Operates in Fast Survey (FS) Mode in the MMS Region Of Interest (ROI) for the current Mission Phase. Data are taken at Burst (30/150 ms for DES/DIS) Resolution in this Mode. Data are also made available at Survey (4.5 s, etc.) Resolution. Per Mission Design, not all Burst Resolution Data are downlinked, but all Survey Data are downlinked. This Product contains Phase Space Distribution Maps of those Burst Resolution Data selected for downlink. In particular, the (highest possible Quality at the Time of Release) corrected/converted "Burst Sky Map" Distributions are reported with Time Stamps and other Annotation characterizing the State of the Instrument System at the indicated Time.

MMS 1 Hot Plasma Composition Analyzer (HPCA) Ions, Level 2 (L2), Survey Mode, 0.625 s Data

Hot Plasma Composition Analyzer (HPCA) Ions, Level 2, Survey, 0.625 s Data. The MMS HPCA instruments measure the energy and composition of magnetospheric plasmas in the energy range from 1 eV to 40 keV. An electrostatic energy analyzer (ESA) that is optically coupled to a carbon-foil based Time-of-Flight (TOF) section comprises each HPCA. The basic HPCA data product is an array of counts for 5 ion species, at 63 energies, for each of 16 elevation anodes. Sixteen basic products, also called azimuths, are acquired every 0.625 s; half a spacecraft spin period nominally has 16 azimuths. The five ion species are protons (H+), alpha particles (He++), helium ions (He+), singly charged Oxygen (O+), and background counts.

VOYAGER 1 SATURN PLASMA DERIVED ION FITS BROWSE 96 SEC

THIS DATA SET CONTAINS ESTIMATES OF THE ION MOMENT DENSITY IN THE PLS VOLTAGE RANGE (10-5950 EV/Q) AT SATURN DURING THE VOYAGER 1 ENCOUNTER. RIGID COROTATION IS ASSUMED, WHICH LEADS TO AN UNDERESTIMATE OF THE DENSITY IN SOME REGIONS, AS DOES THE USE OF AN ACCEPTANCE AREA RELEVANT FOR A COLD BEAM FOR PLASMA WHICH IS TRANSONIC IN SOME REGIONS. DENSITIES MAY BE UNDERESTIMATED BY A FACTOR OF 2-3 IN THE INNER MAGNETOSPHERE, SO THIS DATA SET SHOULD BE USED PRIMARILY FOR STUDIES USING VARIATIONS IN PLASMA DENSITY. THE FIT DENSITIES GIVE A BETTER ESTIMATE OF THE ABSOLUTE DENSITY. THIS IS THE DATA SHOWN AND DESCRIBED IN DETAIL IN LAZARUS AND MCNUTT (1983).
