Abstract: The design of plasma wave receivers for use onboard scientific satellites is introduced. Since space plasmas are collisionless, kinetic energy is transferred via plasma waves. The role of plasma wave receivers is to reveal wave-particle interactions in space plasma. Conventional plasma wave receivers are classified into three types: multichannel analyzers, sweep frequency analyzers, and waveform capture. Each one has their own advantages and disadvantages and thus they complement each other. The present paper provides guidelines for designing plasma wave receivers by referring to examples from representative science missions. Furthermore, the prospects of using plasma wave receivers in future missions are discussed. The mass and size requirements for onboard instruments can be satisfied by developing small receivers. Extremely small plasma wave receivers can be achieved using analog application-specific integrated circuit(ASIC) technology. We also introduce our recent progress in developing a chip that implements the necessary analog components of plasma wave receivers.
Key words: Plasma wave, collisionless plasma, plasma wave receiver, analog ASIC.
