Time Of Flight (TOF) profiles of the solar wind ions, magnetically reflected ions, and ions backscattered at the lunar surface. (a) E-t spectrogram of the ions from the Moon observed by IMA. (b) Magnetic field intensity and altitude of Kaguya. (c)–(e) Energy/charge-TOF spectrograms below the time of flight of 100 nsec. (f)–(h) Energy integrated TOF profile. (i)–(k) Low count part of the energy integrated TOF profile. Charge state of the detected particles is indicated in parentheses in panels (c)–(k).
