AB: The Charge-Energy-Mass Spectrometer (CHEMS), one of three sensors comprising the MIMI investigation on Cassini, measures the mass and charge state of ions in the energy per charge range 3--220 keV/e. During Titan-5, Cassini's fifth close flyby of Titan on day 106, 2005, CHEMS observed an anisotropic flux of heavy ions during a 10-minute period beginning about 1915 UT, 3 minutes after closest approach. The measured ion masses ranged from 14--30 amu. Their energy spectrum exhibited a sharp cutoff above 12 keV. These ions are presumably pickup ions from Titan. We will discuss their composition, anisotropy, and energy spectrum in terms of acceleration by the corotation electric field.
