IMP 8 CPME EPE MAG PLS Merge Data Set
Description

This data set contains 20.48s IMP8 CPME and EPE energetic particle data, along with IMP8 magnetic field and plasma data to facilitate use of the particle data. CPME data consist of: spin-integrated, 20.48s resolution count rates of protons in ten energy channels (0.29-0.50 to 90-440 MeV), of alpha particles in six channels (0.59-1.14 to 28-52 MeV/n), of Z>=3 particles in five channels (0.70-1.45 to 6-105 MeV/n), of electrons in 3 channels (0.22-2.5 to 0.80-2.5 MeV), of protons and alpha particles mixed in two channels (>35, >50 MeV/n) and uncertainties in all the preceding 20-s rates; spin-integrated, 10.24s count rates of protons in three energy channels (0.29-0.50 to 0.96-2.00 MeV) and of electrons in the three energy channels given above, plus uncertainties and data quality flags for all these 10.24s rates; 10.24s count rates in 8 spin sectors for 0.29-0.50 MeV protons and for 0.22-2.50 MeV electrons and their uncertainties and dataquality flags; 20.48s count rates in 8 spin sectors for 0.59-1.14 and 1.8-4.2 MeV/n alpha particles and for 0.7-3.3 and 3.1-8.8 MeV/n Z>= 3 particles, and their uncertainties anddata quality flags. EPE data consist of 16-sectored, 20.48s counts (not rates) for Z>=1 particles in 0.05-0.22 and 0.22-0.80 MeV/n channels, for electrons in 0.03-0.10 and 0.10-0.20 MeV channels and for Z>=1, E>0.015 MeV/n particles and electrons mixed. Magnetic field data include GSE and GSM cartesian components and direction angles. Plasma data, mainly from the MIT Faraday Cup, include flow velocity, density and temperature. Better sources exist for those desiring only IMP8 magnetic field and/or plasma data. Data are available as daily gzipped ASCII files; spin- integrated, 20.48s CPME count rates are also available with display and subset capability via FTPBrowser.

Description

Three solid-state detectors in an anticoincidence plastic scintillator observed electrons between 0.2 and 2.5 MeV; protons between 0.3 and 500 MeV; alpha particles between 2.0 and 200 MeV; heavy particles with Z values ranging from 2 to 5 with energies greater than 8 MeV; heavy particles with Z values ranging between 6 and 8 with energies greater than 32 MeV; and integral protons and alphas of energies greater than 50 MeV/nucleon, all with dynamic ranges of 1 to 1E+6 particles per (sq cm-s-sr). Five thin-window Geiger-Mueller tubes observed electrons of energy greater than 15 keV, protons of energy greater than 250 keV, and X rays with wavelengths between 2 and 10 A, all with a dynamic range of 10 to 1E+8 per (sq cm-s-sr). Particles and X rays, primarily of solar origin, were studied, but the dynamic range and resolution of the instrument also permitted observation of cosmic rays and magnetotail particles. For further details, see T. P. Armstrong et al., J. Geophys. Res., v. 83, p. 5198, 1978.

Description

The purposes of this investigation were (1) to study the propagation characteristics of solar cosmic rays through the interplanetary medium over the energy ranges indicated below, (2) to study electron and proton fluxes throughout the geomagnetic tail and near the flanks of the magnetosphere, and (3) to study the entry of solar cosmic rays into the magnetosphere. The instrumentation consisted of a three-element telescope employing fully depleted surface-barrier solid-state detectors and a magnet to deflect electrons. Two side-mounted detectors were used to measure the deflected electrons. Two additional detectors in separate mounts were used to measure charged particles above 15 keV (F), Z greater than or equal to 2 above 0.6 MeV (G1) and above 1.0 MeV (G2), and Z greater than or equal to 3 above 2.0 MeV (G3). The telescope measured protons in three ranges between 2.1 and 25 MeV (14, 15, 16); Z greater than or equal to 1 in three ranges between 0.05 and 2.1 MeV (11, 12, 13); alpha particles between 8.4 and 35.0 MeV in two ranges (111, 112); Z greater than or equal to 2 between 2.2 and 8.4 MeV (110); and a background channel (19). Deflected electrons were measured in two ranges between 30 and 200 keV (17, 18). A complete description of the instrument was given by D. J. Williams in NOAA Technical Report ERL 393-SEL 40, October 1977.

Name
IMP 8 Magnetic Field Experiment
Alternate name
IMP8 MAG
Description

The magnetic field experiment on the IMP-8 spacecraft utilizes a tri-axial fluxgate (saturable inductor) magnetometer. The instrument originally had three, automatically determined, ranges, +/-12 nT, +/-36 nT, and +/-108 nT, full scale. Because of a range-change circuit failure occurring in early July 1975, the experiment was commanded into a fixed +/-36 nT range on July 11, 1975 at 12:55:09 UT and has been in that range ever since. The measurements are A-to-D converted onboard, to an 8-bit resolution, yielding +/-0.14 nT quantization sensitivity, which is larger than the intrinsic sensor noise level of 0.025 nT RMS. The data from the two-bit (per component) adaptive delta modulator, incorporated into the instrument, and applied to the intrinsic sample rate of 25 vectors/sec., was never utilized, and hence the rate of the full (8-bit) vector words, which occur every 320 ms, represents the effective sample period of the instrument. The sampling rate is synchronized to the spacecraft clock; the basic spacecraft clock frequency is 6.4 kHz. The sensor unit is mounted on the end of a boom approximately 4 m from the center of the spacecraft.

Name
IMP 8 Solar Plasma Faraday Cup
Alternate name
IMP 8 PLS
IMP 8 PLA
1973-078A-02
Description

A modulated split-collector Faraday cup, perpendicular to the spacecraft spin axis, was used to study the directional intensity of positive ions and electrons in the solar wind, transition region, and magnetotail. The collector plate split is perpendicular to the spacecraft spin axis in order to measure the flow angle of the ions in a meridional plane; the flow angle in the spacecraft equatorial plane is determined from the fluxes measured as the spacecraft rotates. Electrons are measured using 21 logarithmically-spaced energy windows covering the energy/charge range between 23 and 1935 volts. Positive ions are studied using 24 energy windows covering the range between 50 and 7000 volts. The instrument has three operating modes. The tracking mode yields the best time resolution which is about 1 minute. A single energy window is used during a spacecraft rotation. The ion spectrum is obtained in eight spacecraft revolutions using a subset of the energy windows that track the peak of the solar wind. In this mode, fluxes are measured during 11.25-degree sectors of the spacecraft spin while the instrument is looking within the 90 degree sector centered on the sun direction and during 45 degree sectors for the remainder of the rotation. The other modes yield a spectrum using all 24 windows (with the same angular sectors described above) or a spectrum that results from integrating the observed fluxes over 45 degree sectors for the entire spacecraft rotation. Electron data are obtained in all modes, but are not usually analyzed. Parameters derived on a routine basis are proton velocity, number density, and temperature (most probable thermal speed). Those parameters are obtained from a non-linear, least-squares fit to the observed fluxes using a convected, isotropic Maxwellian model. Key Parameters for the Plasma instrument are computed at MIT using Level Zero data that are staged to the ISTP/CDHF approximately two weeks after being received on Earth. Thus the plasma instrument's Key Parameters lag real time by something greater than 2 weeks, but less than four.

1973-078A
Description

IMP 8 (IMP-J or Explorer 50), the last satellite of the IMP series, was a drum-shaped spacecraft, 135.6 cm across and 157.4 cm high, instrumented for interplanetary and magnetotail studies of cosmic rays, energetic solar particles, plasma, and electric and magnetic fields. Its initial orbit was more elliptical than intended, with apogee and perigee distances of about 45 and 25 earth radii. Its eccentricity decreased after launch. Its orbital inclination varied between 0 deg and about 55 deg with a periodicity of several years. The spacecraft spin axis was normal to the ecliptic plane, and the spin rate was 23 rpm. The data telemetry rate was 1600 bps. The spacecraft was in the solar wind for 7 to 8 days of every 12.5 day orbit. Telemetry coverage was 90% in the early years, but only 60-70% through most of the 1980's and early 1990's. Coverage returned to the 90% range in the mid to late 1990's. The objectives of the extended IMP-8 operations were to provide solar wind parameters as input for magnetospheric studies and as a 1-AU baseline for deep space studies, and to continue solar cycle variation studies with a single set of well-calibrated and understood instruments. In October, 2001, IMP 8 was terminated as an independent mission. Telemetry acquisition resumed after about three months at Canberra only (30-50% coverage), as an adjunct to the Voyager and Ulysses missions. As of August 2005 IMP 8 continued in this mode.

Description

The IMP spacecraft series. Prelaunch, the 10 IMP's were called IMP's A-J. 8 of them were intended for geocentric orbits (A-C, F-J) and 2 for selenocentric orbits (D,E). Prelaunch, the latter two were also called Anchored IMPs (AIMPs) A and B. After launch, the 8 intended for geocentric were also called IMPs 1-8 and the 2 intended for lunar orbit were called AIMP 1 and 2. Only IMP E = AIMP B = AIMP 2 achieved lunar orbit; IMP D = AIMP A = AIMP 1 went into a geocentric orbit. The mapping of prelaunch IMP letters to postlaunch Explorer numbers and IMP numbers was
