Plasma trapping potential has been generated and studied in the collision chamber containing Argon at pressure 10-4 mb . the plasma trap was generated due to annular electron beam of density n = lx 10 12 cm-3. The electron beam, generated the plasma, due to collision with back ground gas and entrained the plasma because of its annular geometry . Plasma trap phenomena was studied which gave an ion source with extraction efficiency of over 60 % , the rest was exigent for plasma trapping survival.
