Abstract

The magnetometer (MAG) is one of the ten scientific instruments on the Interstellar Mapping and Acceleration Probe (IMAP), which will take in situ and remote measurements from a Sun-Earth L1 halo orbit. MAG contributes to IMAP science goals of investigating the acceleration and propagation of energetic particles, as well as providing real-time space weather monitoring data. The magnetometer is a conventional dual sensor fluxgate instrument with a noise floor under 10 pT at 1 Hz, taking science measurements continuously at 2 vectors/s as well as a burst mode of 64 vectors/s for at least 8 hours per day. It also provides a real-time space weather monitoring product at 4 second cadence. We describe the requirements, design and performance of the instrument, including a novel lossless compression algorithm. Data products, processing and calibration plans are presented.

IMAP磁力计。

磁力计（MAG）是星际测绘和加速探测器（IMAP）上的十个科学仪器之一，它将在太阳-地球L1晕轨道上进行原位和远程测量。MAG有助于实现IMAP的科学目标，即研究高能粒子的加速和传播，以及提供实时空间天气监测数据。该磁力计是一种传统的双传感器磁通门仪器，噪声底限低于10 pT，频率为1 Hz，每天至少8小时以2个矢量/秒的速度连续进行科学测量，以及64个矢量/秒的突发模式。它还提供以4秒为周期的实时空间天气监测产品。我们描述了仪器的要求、设计和性能，包括一种新的无损压缩算法。给出了数据产品、处理和校准方案。

期刊介绍： Space Science Reviews (SSRv) stands as an international journal dedicated to scientific space research, offering a contemporary synthesis across various branches of space exploration. Emphasizing scientific outcomes and instruments, SSRv spans astrophysics, physics of planetary systems, solar physics, and the physics of magnetospheres & interplanetary matter. Beyond Topical Collections and invited Review Articles, Space Science Reviews welcomes unsolicited Review Articles and Special Communications. The latter encompass papers related to a prior topical volume/collection, report-type papers, or timely contributions addressing a robust combination of space science and technology. These papers succinctly summarize both the science and technology aspects of instruments or missions in a single publication.
