Abstract
The paper deals with investigations of secondary emission of 1-6 micro-meter spherical grains from amorphous carbon under the electric field of the order of 108 V/m. The secondary emission yield increases with the electric field at the sample surface linearly and does not depend on the grain diameter.
Long-lasting (hours) electron irradiation of the sample surface leads to a significant decrease of the yield
