The Electric Field Instrument (EFI) for the TRACERS Mission.
The Electric Field Instrument (EFI) for the NASA Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission provides measurements of the electric field from DC to nearly 10 MHz on two closely-spaced spacecraft in low Earth orbit passing through the terrestrial cusp region. As measured by EFI, the plasma convection fields, ULF and ELF fluctuations, and natural HF emissions provide key measurements of plasma flow, plasma waves, and plasma density that support all three science objectives of the TRACERS mission. Here, we describe the mechanical and electrical design of the EFI, the data products it produces, and the concept of its on-orbit operations.
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.
