Name
SAMPEX Polar-Cap-Averaged Fluxes, all instruments
Description

This data set contains 17 differential fluxes of protons (mainly), helium ions, Z.GE.6 ions, and electrons, plus one integral flux of protons and electrons, as averaged over polar cap passes of the SAMPEX spacecraft. A polar cap pass covers the time poleward of geomagnetic latitude 70 deg. (Not all orbits have two polar cap passes.). For any given species, the fluxes typically come from more than one of the sensors (LICA, HILT, MAST, PET). Hence the inclusion of all instruments' data in each single record. Differential fluxes are those for (mainly) protons (Z.GE.1 channels at 5-12 and 19-27 MeV/n), helium ions (0.50-6.6, 4-9, 8-15, 9-38 MeV/n), Z.GE.6 ions (0.49-8.3, 8-42, 19.3-22.8, 22.8-31.0, 31.0-51.7, 41-220, 51.7-76.2, 76.2-113, 113-156 MeV/n), and electrons (1.5-6.0 MeV from PET only). One LICA channel measured integral fluxes of ions .GT. 0.8 MeV/n plus electrons .GT. 0.6 MeV). Data available for each polar cap pass are time tags of the begin and end points of the averaging interval, the fluxes, statistical uncertainties in the fluxes, instrument-specific flags, and a flag indicating a north or south polar cap pass. Data are organized in two different ways. Monthly ~500-KB ASCII files with records organized by instrument are available from the SAMPEX Data Center at Caltech and from nssdcftp at GSFC/SPDF, while monthly ~260 KB CDF-formatted files with records organized by species are available from the ftp area underlying CDAWeb. The parameter level information given below in this descriptor corresponds to the CDAWeb organization of data. Format information for the ASCII version is given in the Information URL of this descriptor.

Name

Alternate name
MAST
Description

MAST was an 11 layer array of detectors, each of area >20 cm**2, stacked one below the other. The first four of these, M1, M2, M3, and M4, were surface-barrier, one-dimensional, position sensitive detectors, each having 92 coplanar, parallel electrode strips with 0.5 mm pitch. The combination of these four layers enabled determination of the X-Y coordinates at two positions, and hence the exact trajectories of penetrating nuclei. Following these were two more surface-barrier detectors, D1 and D2. Further downstream were lithium-drifted solid state detectors, D3 through D7. The areas and thicknesses of the detectors were as follows: M1--M4:20 cm**2, 115 micrometer; D1:20 cm**2, 175 micrometer; D2:20 cm**2, 500 micrometer; D3 through D7 had area of 30 cm**2, with thicknesses, respectively, of 1.8 mm, 3.0 mm, 6.0 mm (compound stack of 2 3.0 mm detectors), 9.0 mm (compound stack of 3 3.0 mm detectors), and 3.0 mm. The signal from the last-penetrated detector measured the residual energy E', and the upstream detectors provided dE/dx with abundant redundancy. The trajectory system, together with preflight calibrations at the Bevalac particle accelerator, enabled considerably more precision in isotopic mass determination, i.e., 0.2 amu, than would otherwise have been possible for the energy range of 10 MeV/nucleon to several hundred MeV/nucleon, and charge ranges of 3 <= Z <= 28. The on-board DPU enabled down-linking of data from Z > 3 events on a priority basis. For more information, see IEEE Transactions on Geoscience and Remote Sensing, vol 31, May 93, pp 557-564. The instrument functioned normally as of 15 July 1996; the next update will be only when any significant status change occured.

Instrument: Heavy Ion Large Telescope (HILT)

Instrument ID
spase://SMWG/Instrument/SAMPEX/HILT Get XML
Name
Heavy Ion Large Telescope (HILT)
Alternate name
HILT
Description

The HILT experiment was designed to measure the charge, energy, and mass of cosmic rays in the energy range of about 8.0--310 MeV/nucleon. Specifically, the energy ranges were: He:3.9--90 MeV/nucleon; C:7.2--160 MeV/nucleon; O:8.3-310 MeV/nucleon; Ne:9.1--250 MeV/nucleon; and, Fe:11--90 Mev/nucleon. The instrument consisted of (a) an array of position sensitive proportional counters at the entrance, followed by (b) an ionization chamber, (c) another array of position sensitive proportional counters just before, (d) a coplanar, 10-element, solid state array of detectors. The detectors were backed by, (e) a large CsI scintillation counter which was viewed by four light sensitive diodes. The geometric factor was as large as 35 cm**2-sr. The two position sensitive counters enabled computation of the exact length of the trajectory along the ionization chamber. Items (a), (b), and (c) were filled with flowing, isobutane gas at a pressure of 75 Torr. The 8.5 kg of liquid isobutane was sufficient for a three year operation. The instrument was basically a dE/dx vs. E system; dE/dx was provided by (a), (b), and (c), and E was provided by (d) and (e). The telemetered signals from all the sensors enabled accurate determination of isotopic mass, charge and energy. However, isotopic resolution was poor at the high energy end of each band, especially for the heavier elements. Species dependent fluxes were, however, readily computed even at the high energy ends. For more details, see IEEE Transactions on Geoscience and Remote Sensing, vol 31, May 93, pp 542-548. The instrument functioned normally as of 15 July 1996; the next update will be only when any significant status change occured.

Instrument ID

Name
Proton-Electron Telescope (PET)
Alternate name
PET
Description

PET consisted of an array of eight, lithium-drifted solid state detectors, together covering the energy range of 1--30 MeV for electrons, 18--85 Mev/nucleon for H and He, and 54--195 MeV/nucleon for the heavier elements. The geometric factors were about 1.0 cm**2-sr. H and He could be tracked into several hundred MeV/nucleon range, but with a reduced geometric factor of 0.3. The top-most detectors, P1 (convex) and P2 (concave) were each 2 mm thick, and had area of 8.1 cm**2. Downstream were the remaining, flat detectors P3 through P8, with the following dimensions. P3: 9.2 cm**2, 15 mm (compound stack of 5 3 mm detectors); and P4--P8: 4.5 cm**2, 3 mm. The instrument could be operated in a low gain (high-Z) mode or, ordinarily, in low-Z mode for observation of protons, electrons, and helium. Pulse height from the last-penetrated detector enabled determination of total E, and the upstream detectors provided dE/dx with enough redundancy to enable accurate determination of particle type. The counting rate of P1 was recorded with a resolution of 0.1 seconds, enabling observation of rapid time variations in the flux of precipitating electrons above energies of 0.4 MeV. (See IEEE Transactions on Geoscience and Remote Sensing, May 1993, vol 31, pp 565-574.) The instrument functioned normally as of 15 July 1996; the next update will be only when any significant status change occured.

Instrument: Low-Energy Ion Composition Analyzer (LICA)

Instrument ID

Name
Low-Energy Ion Composition Analyzer (LICA)
Alternate name
LICA
Description

The LICA experiment was designed to measure 0.5--5 MeV/nucleon solar and magnetospheric ions (He through Ni) arriving from the zenith in twelve energy bands. The mass of an ion was determined with simultaneous measurements of its time-of-flight (TOF) across a path length of approximately 50 cm and its residual kinetic energy in one of four 4 x 9 cm silicon solid state detectors. Ions passing through the 0.75 micrometer nickel entrance foils emitted secondary electrons which a chevron microchannel plate assembly amplified to form a signal to begin timing. A double entrance foil prevented single pinholes from allowing sunlight to enter the telescope and provided immunity to solar and geocoronal ultraviolet. Another foil and microchannel plate assembly in front of the solid state detectors gave the signal to stop timing. Wedge-and-strip anodes on the front sides of the timing anodes determined where the ion passed through the foils and, therefore, its flight path length. The velocity determined from the path length, the TOF, and the residual energy measured by the solid state detectors were combined to yield the mass of the ion with a resolution of about 1%, adequate to provide complete isotope separation. Corrections for the energy loss in the entrance foils gave the ion's incident energy. The geometric factor of the sensor was 0.8 sq cm sr and the field of view was 17 x 21 degrees. On-board processing determined whether ions triggering LICA were protons, He nuclei, or more massive ions. Protons were counted in a rate and not further analyzed. Heavier nuclei were treated as low (He) or high (more massive than He) priority for transmission to the ground. The instrument data processing unit ensured that a sample of both priority events was telemetered, but that low priority events did not crowd out the rarer heavy species. Processed flux rates vs. energy of H, He, O, Si group, and Fe groups were picked out every 15 s for transmission. Appropriate magnetic field models enabled specification of the atomic charge state by means of rigidity cut-off calculations. In addition, the proton cut-off vs. energy during an orbit helped charge identification of the other species. On-board calibrations of the sensor were done by command about once per week. Data was stored in on-board memory of 26.5 MB, which was then dumped twice daily over ground stations. The instrument functioned normally as of 15 July 1996; the next update will be only when any significant status change occured.

Solar Anomalous and Magnetospheric Particle Explorer
Description

The Solar Anomalous and Magnetospheric Particle Explorer (SAMPEX) is the first of a series of spacecraft that was launched under the Small Explorer (SMEX) mission of program for low cost spacecraft. The main objectives of SAMPEX experiments was to obtained data for several continuous years on the anomalous components of cosmic rays, on solar energetic particles emissions from the sun, and on the precipitating magnetospheric relativistic electrons. The orbit of SAMPEX has an altitude of 512 by 687 km and an 81.7 degree inclination. The spacecraft uses an on-board 3-axis stabilized solar pointed/momentum bias system with the pitch axis pointed to towards the sun. Solar panels provide power for operations, including 16.7 W for science instruments. An on-board DPU preprocesses the science and other data and stores them in a RPP unit of about 65 Mb, before transmitting in the S-band at a rate of 1.5 Mb/s over Wallops (or a back-up) station. The command memory can store at least a thousand commands. The science instruments generally point toward local zenith, especially over the terrestrial poles, for optimal sampling of galactic and solar cosmic ray flux. Energetic magnetospheric particle precipitation is monitored at lower geomagnetic latitudes. It carries four science instruments: (1) low energy ion composition analyzer (LICA); (2) heavy ion large telescope (HILT); (3) mass spectrometer telescope (MAST); and (4) proton electron telescope (PET). Estimated useful lifetime of the spacecraft was about three years; however, the data stream continue to July, 2004. In 1997, NASA Goddard transferred operation of SAMPEX to the Flight Dynamics and Control Laboratory (FDCL) housed within the Aerospace Engineering Department of the University of Maryland. For more details, see IEEE Transactions on Geoscience and Remote Sensing (Vol 31, Issue 3, May 1993, pp. 531-574).
