An integrated ΔE-E ionization detector that includes an outer shell having an interior linear axis, a vacuum tube coaxial with the linear axis, and a front cathode, a center anode, and a rear anode disposed within the outer shell and around the vacuum tube. The front cathode, center anode, and rear anode are substantially planar in shape, and a ΔE detection chamber is defined by the front cathode, the center anode, the outer shell, and the vacuum tube, and an E detection chamber is defined by the rear anode, the center anode, the outer shell, and the vacuum tube. All rays defining at least one solid annular angle about the linear axis and originating from a point in front of the front cathode will intersect the front cathode, internally traverse the ΔE detection chamber, intersect the center anode, and traverse at least a portion of the E detection chamber.
