Due to the importance both in fundamental researches and in many related techniques and applications, the investigation of secondary electron emission (SEE) from surface induced by heavy ions has attracted a lot of attention during the past decades[1-4]. There were many studies on SEE from foils induced by ions in the medium and high energy region (above Bohr velocity, >25 keV/u), but few experiments have been focused on the near or below Bohr velocity region. The experiment on SEE from both sides of a carbon foil induced by multi-charged heavy ions was carried out at HV-ECR platform. Fig.1 shows the typical results of the measurements, where a carbon foil with thickness of 17 μg/cm2 was bombarded by Ne2+ with energy ranging from 2 to 25 keV/u.
