Yoshikawa, I., Yamazaki, A., Shiomi, K., Yamashita, K., Takizawa, Y. and Nakamura, M. (2000). Photometric measurement of cold helium ions in the magnetotail by an EUV Scanner onboard planet-B: Evidence of the existence of cold plasmas in the near-Earth plasma sheet. Geophysical Research Letters 27: doi: 10.1029/2000GL000100. issn: 0094-8276.

The first optical measurement of He+ ions in the plasma sheet was successful by using the XUV scanner onboard Planet-B. The intensity of He II (304 ¿) was ~0.02 Rayleigh. This result encourages future imaging missions for the whole magnetosphere by detecting He II (304 ¿) emission. This is also a proof of the existence of cold plasmas in the plasma sheet. The existence of cold ions brings a new question: How can they remain cold in the plasma sheet? ¿ 2000 American Geophysical Union
