Claim 1
Independent Claim
110 words
In an electron discharge device, an elongated anode defining a cylinder having an axis, said anode being permeable to the flow of charged particles therethrough in directions generally transverse to said axis, an elongated dynode sleeve concentrically surrounding said anode and radially spaced therefrom, the interior surface of said dynode sleeve having secondary emissive properties, and means for energizing said anode and dynode sleeve thereby to cause circulatory electron flow within said dynode sleeve through said anode generally transverse to said axis, said interior surface of said dynode sleeve having undulations therein so that a preponderance of the electrons flowing through said anode bypass the region immediately surrounding said axis.
Claim 2
Dependent Claim
110 words
In an electron discharge device, an elongated anode defining a cylinder having an axis, said anode being permeable to the flow of charged particles therethrough in directions generally transverse to said axis, an elongated dynode sleeve concentrically surrounding said anode and radially spaced therefrom, the interior surface of said dynode sleeve having secondary emissive properties, and means for energizing said anode and dynode sleeve thereby to cause circulatory electron flow within said dynode sleeve through said anode generally transverse to said axis, said interior surface of said dynode sleeve having undulations therein so that a preponderance of the electrons flowing through said anode bypass the region immediately surrounding said axis.
