Name
ACE SIS 1-Hour Level 2 Data
Description

ACE Solar Isotope Spectrometer (SIS) hourly intensities and count rates, for each of 14 elements (He,C,N,O,Ne,Na,Mg,Al,Si,S,Ar,Ca,Fe,Ni). in each of 8 energy bins. Overall energy ranges covered go from 3.4-41 MeV/n for helium to 10.5-168 MeV/n for iron. These are calibrated science quality data. The data are accessible via ftp in HDF and CDF from the ACE Science Center and CDAWeb, respectively, and in ASCII format from the value-added interfaces at those sites. The "parameter keys" given below are as used by CDAWeb.

Caveats

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.

Instrument: Solar Isotope Spectrometer (SIS)

Instrument ID
spase://SMWG/Instrument/ACE/SIS Get XML
Name
Solar Isotope Spectrometer (SIS)
Alternate name
SIS
1997-045A-05
Description

The Solar Isotope Spectrometer (SIS) experiment provides measurements at isotopic resolution of elements from He through Zn (2 < Z < 31) at energies of 10 - 100 MeV/nucleon. This energy range includes energetic ions accelerated by solar flares, coronal shocks, interplanetary shocks, and the solar wind termination shock (i.e., the anomalous cosmic ray component). Measurements of galactic cosmic ray ions are made at lower energies not covered by the Cosmic Ray Isotope Spectrometer (CRIS) instrument. The detector system consists of two identical charged particle telescopes composed of large-area silicon solid-state detectors. Each telescope consists of a hodoscope system made up of a pair of 2-D position-sensing detectors (M1 and M2), followed by an energy loss stack with eight detectors (T1 to T8) of varying thicknesses. Precise measurements of incident ion trajectories are provided by the position-sensing detectors (PSD's), each being 60 microns thick with 64 parallel "X" or "Y" strips on the top and bottom. Each such strip is separately pulse-height analyzed for energy loss determination and identification of multiple track events. The T1 - T8 detectors are composed of various combinations of 1-mm thick solid state elements linked electronically. T1 to T5, and T8, consist of one 1-mm element, whereas T6 includes three such elements and T7 includes six. Detectors T1 - T7 are pulse-height analyzed for energy loss measurements, and T8 is used to identify penetrating events. Acquisition of pulse-height event, counting rate, and housekeeping data is similar to that for CRIS, except that the pulse-height data volume varies from event to event and is minimal for the more abundant events from solar flares. The average event length is about 200 bits, which gives 10 events per second at the nominal 2 kbps telemetry rate. Since data for all heavy (Z > 5) ion events cannot be acquired in some large solar flare events, a priority system selects events for telemetry based on estimated charge, energy (range in the detector stack), and event quality, the more penetrating heavy ions having greatest priority.

Advanced Composition Explorer
1997-045A
Explorer 71
Description

The objective of the Advanced Composition Explorer (ACE) is to collect observations of particles of solar, interplanetary, interstellar, and galactic origins, spanning the energy range from that of KeV solar wind ions to galactic cosmic ray nuclei up to 600 MeV/nucleon. Definitive studies will be made of the abundances of essentially all isotopes from H to Zn (Z = 1-30), with exploratory isotope studies extending to Zr (Z = 40). The ACE payload includes six high resolution spectrometers, each designed to provide the optimum charge, mass, or charge-state resolution in its particular energy range. Each spectrometer has a geometry factor optimized for the expected flux levels, so as to provide a collecting power greater by a factor of 10-1000 times that of previous or planned experiments. The payload also includes three additional instruments of standard design to monitor energetic electrons, H and He ions, and a magnetometer. The ACE spacecraft is based on the design of the Charge Composition Explorer, built at JHU/APL for the Active Magnetospheric Particle Tracer Explorer (AMPTE) program. The spacecraft spin axis is pointed towards the Sun to within +/- 20 degrees, and it occupies a halo orbit about the L1 Earth-Sun libration point. Powered by solar cells, the spacecraft has a design life of at least five years, and it returns data in daily tape recorder dumps, received through NASA JPL's Deep Space Network and initially processed at NASA-GSFC. The average data telemetry rate is 6.7 Kbs.
