Production of a Highly Ionized Ion Beam by a Plasma Focus

概要

論文の詳細を見る
Generation of the highly charged ions such as C" -C" using the Mather typeplasma focus is carried out. Measurement of the energy distribution with a Thomsonparabola analyzer shows that the maximum energ)z per charge state extends to - 1.5MeV /'Z, for each species approximately. Generation of such huge electric field to ac-celerate ions is reasonably explained by an anomalous plasma resistivity induced inthe collapsed plasma column. The discrepancy between the iu?duced voltage and theobserved one across the collector plates is discussed taking the capacitance of the coaxial electrode into account. A microchannel plate which is extremely useful for thetime dependent ion measurement is calibrated for energetic tons of C" - C" by theproduced ion beams.highly ionized ion beam, plasma focus, anomalous resistivity
