The nuclei detected in this energy interval are predominantly The Solar Isotope Spectrometer (SIS) provides high-resolution measurements of the isotopic composition of energetic nuclei from He to Zn (Z = 2 to 30) over the energy range from ~10 to ~100 MeV/nucleon. Their purpose is to allow monitoring in disturbed conditions downstream from shocks, including CIRs; and elsewhere in the heliosphere. generated from the spacecraft data stream using simple algorithms provided by The charge state of energetic ions contains key information to unravel source temperatures, acceleration, fractionation, and transport processes for these particle populations.

McComas et al.ACE also measures abundances of cosmic ray nickel-59 and cobalt-59 isotopes; these measurements indicate that a time longer than the half-life of nickel-59 with bound electrons (7.6 × 10 ACE observes particles of solar, interplanetary, interstellar, and galactic origins, spanning the energy range from solar wind ions to galactic cosmic ray nuclei to better understand the formation and evolution of the solar system. This data center does not have any addresses listed. and between ACE data and data from other sources.

samples of matter, including the solar corona, the interplanetary Real-time data from ACE is used by the ACE observations allow the investigation of a wide range of fundamental problems in the following four major areas:A major objective is the accurate and comprehensive determination of the elemental and isotopic composition of the various samples of "source material" from which nuclei are accelerated. being managed by the Office of Space Science Mission and Payload These observations have been used to: an interplanetary shock. The ACE data includes energetic particles from solar wind See: http://www.srl.caltech.edu/ACE/ASC/browse/browse_info.html The measurements of proton density, speed, and thermal speed by SWICS were not affected by this anomaly and continue to the present day.The Electron, Proton, and Alpha Monitor (EPAM) instrument on the ACE spacecraft is designed to measure a broad range of energetic particles over nearly the full unit-sphere at high time resolution. The ACE spacecraft measures the flux of charged particles from solar Currently, warnings of geomagnetic storms are made using terrestrial data and real-time solar wind data obtained from the Advanced Composition Explorer (ACE) spacecraft, stationed on a halo orbit about the L 1 Lagrange point some 1.5 million km (0.01 AU) sunward of the Earth, as shown in Figure 7.8. ACE also provides near-real-time solar wind information over short periods of time for space weather forecasting. This data center does not have any addresses listed. to the public domain as soon as possible. JHU/APL SWICS determined uniquely the chemical and ionic-charge composition of the On August 23, 2011, the SWICS time-of-flight electronics experienced an age- and radiation-induced hardware anomaly that increased the level of background in the composition data. The ACE Science Center (ASC) serves to facilitate collaborative work on data from the Advanced Composition Explorer(ACE) spacecraft and to ensure that those data are properly archived and publicly available. behavior and for selecting interesting time periods. NASA's Advanced Composition Explorer (ACE) collects and analyzes particles of solar, interplanetary, interstellar and galactic origins. Interesting SEPICA had the ability to resolve individual charge states with a substantially larger geometric factor than its predecessor ULEZEQ on ISEE-1 and -3, on which SEPICA was based. This data center does not have any contact mechanisms listed. ACE measurements confirm that CIRs include a significant fraction of singly charged helium formed when interstellar neutral helium is ionized.At yet higher energies, the major contribution to the measured flux of particles is due to solar energetic particles (SEPs) associated with interplanetary (IP) shocks driven by fast coronal mass ejections (CMEs) and solar flares. Advanced Composition Explorer (ACE) is a NASA Explorers program Solar and space exploration mission to study matter comprising energetic particles from the solar wind, the interplanetary medium, and other sources.

The data are automatically magnetic field, and solar wind parameters such as proton speed and temperature. Po starcie 25 sierpnia 1997, sonda została skierowana na orbitę Lissajous wokół punktu L 1 układu Ziemia – Słońce , skąd prowadzi pomiary in situ cząstek pochodzących z korony słonecznej , ośrodka … wind energies (300 km/sec) up through galactic cosmic rays (500 Advanced Composition Explorer (ACE) Particle Composition and Flux Browse Data The Advanced Composition Explorer (ACE) is an Explorer mission that is being managed by the Office of Space Science Mission and Payload Development Division of the National Aeronautics and Space Administration (NASA).
