چکیده
|
In this paper new structure of a plasma electron source has been described. this electron source can produce apowerful and monochromatic electron beam by a simple obstructed discharge mechanism. the beam current anddiode current has been measured for low pressure he discharges under the influence of an external longitudinalmagnetic field. the magnetic field could vary from 0 to 45 mt. voltage-current characteristics and paschen curveshas been obtained under mentioned conditions. the results show that by increasing of magnetic field, efficiency ofthe system significantly enhances but it decreases at higher magnetic field values.
