| 10 | 10 | <Description>The dual-sensor spectrometer RAPID (Research with Adaptive Particle Imaging Detectors) analyzes suprathermal plasma distributions in the energy range from 20--400 KeV for electrons and from 2 KeV/nucleon to 1.50 MeV/nucleon for ions. Angular distributions are measured over a range of 180 degrees in polar angle for either species. Electrons are identified by the well-known energy-range relationship. The detection principle for ions is based on a two-dimensional analysis of a particle's velocity and energy. Moderate mass resolution of about four (for oxygen ions) permits the identification of ions and ion groups of significance. Particle species identified are electrons, protons, He and CNO group ions, and energetic neutral atoms of energies 10--100 KeV. RAPID science data are transmitted through a complex data format, using 17 Kbps in the telemetry nominal mode. Time resolution is as high as 16 samples/spin for certain elements. The nominal spin period for the spacecraft is 4 s. The RAPID field of view covers a range of 180 degrees with respect to the spin vector. The sensor systems, IIMS and IES, scan the full range of the solid angle as the spacecraft rotates. The data returned will be used to project the intensity distribution in distant particle sources on a spherical or plane image area with 192 pixels for IIMS and 144 pixels for IES. The Imaging Ion Mass Spectrometer (IIMS) sensor system is composed of three identical SCENIC (Spectroscopic Camera for Electrons, Neutral and Ion Composition) heads. The sensor systems of IIMS are identical to those in the HEP-LD instrument included in the Japanese Geotail spacecraft. The IIMS uses two-dimensional time-of-flight/energy analysis to determine particle mass. The addition of position-sensing techniques on the entrance foil, in combination with a geometrically small stop detector at the end of the flight path provides directional sensitivity. This approach divides the 180 degree polar segment into twelve contiguous angular intervals. Sectoring the spacecraft spin plane with a maximum of sixteen azimuthal intervals covers the unit sphere in velocity space completely with a total of 192 angular bins. The Imaging Electron Spectrometer (IES) achieves directional sensitivity by using novel microstrip solid-state devices in combination with a pin-hole acceptance. This technique divides the 180 degree polar range into nine angular intervals which, with sixteen sectors in the spin plane, corresponds to a total of 144 bins on the unit sphere. The RAPID spectrometer is connected to the magnetic field instrument FGM through the inter-experiment link. FGM sends 64 uncorrected magnetic field vectors per spacecraft rotation. These are used by the data processor to determine, for each of the sixteen azimuthal sectors, which look directions in the IIMS and IES fans are perpendicular to the current magnetic field vector. For more details of the Cluster mission, the spacecraft, and its instruments, see the report ``Cluster: mission, payload and supporting activities,'' March 1993, ESA SP-1159, and the included article ``RAPID: The Imaging Energetic Particle Spectrometer on Cluster,'' by B. Wilken et al., from which this information was obtained.</Description> |

| 10 | 10 | <Description>This experiment (STAFF: Spatio-Temporal Analysis of Field Fluctuations) is one of the five complementary experiments which form the Wave Experiment Consortium (WEC) on Cluster. STAFF consists of: (1) a triaxial boom-mounted search-coil magnetometer to measure the magnetic components of electromagnetic fluctuations (up to 4 KHz); and, (2) a spectrum analyzer to compute the 25 auto- and cross-correlation coefficients of the spectral matrix, using three magnetic and two electric components of the waves. The magnetic waveform (up to either 10 Hz or 180 Hz) is also transmitted. The Z-axis sensor is parallel to the spacecraft spin axis. Each sensor consists of a high-permeability core embedded inside two solenoids. The frequency response of the main winding is flattened by a secondary winding through a flux feedback effect, in the range 40--4000 Hz. Further, the secondary winding is used as a calibration loop to which an external AC signal is applied. In normal bit rate the wave-form data cover the 0.1--10 Hz frequency range, and the spectrum analyzer covers the range 8 Hz to 4 KHz. In high bit rate, the wave-form data cover 0.1--180 Hz and the spectrum analyzer covers 64 Hz to 4 KHz, using only the two highest frequency bands. In the base mode in normal bit rate the auto-spectra are averaged over 1 s, and the complete 25-component matrix is averaged over 4 s for five components. In high bit rate, only the two highest frequency bands are analyzed. In the fast modes, time resolution is 1 s for the cross-spectra, and either 0.125 s or 0.25 s for the auto-spectra. Other modes are also defined. The analysis will also use electric field waveform data from the EFW (part of WEC), and the hardware of the two instruments was designed to optimize correlation: low-pass filters are identical, sampling frequency is the same, and there is a synchronization signal for simultaneous sampling. The output signals of the STAFF magnetic preamplifiers are also sent to two other instruments: the WBD (part of WEC) and the EDI. Some of the magnetospheric structures to be studied are of small scale, and where the signature duration is of the order 1 s or less, the STAFF search coil data are complementary to those of the fluxgate magnetometer (FGM). For more details of the Cluster mission, the spacecraft, and its instruments, see the report ``Cluster: mission, payload and supporting activities,'' March 1993, ESA SP-1159, and the included article ``The STAFF (Spatio-Temporal Analysis of Field Fluctuations) Experiment for the Cluster Mission'', by N. Cornilleau-Wehrlin et al., from which this information was obtained.</Description> |
