A multicell x-ray detector includes a chamber for confining a gas that produces electron-ion pairs incidental to absorbing radiation. A unitary multicell electrode assembly is mounted within the chamber. The assembly includes a plurality of electrode plates secured in first and second insulating members. A method is provided for bonding the electrode plates into the insulating members with a uniform distribution of adhesive which does not allow the adhesive to bridge between adjacent plates. The opposed ends of the plurality of electrode plates are inserted into grooves of the members. A relatively non-viscous liquid adhesive is brought into contact with one edge of each of the grooves of both members by a cellular applicator until the adhesive propagates by capillary action along the entire length of each groove. The cellular applicator and the adhesive are such that the adhesive has a greater adhesive attraction to the applicator than to the adjacent plates, and such that the adhesive has a lesser adhesive attraction to the applicator than to the grooves of the members. The adhesive will therefore flow from the applicator to the grooves of each member until each groove is filled and any excessive adhesive will be attracted back to the applicator, rather than to the adjacent plates of the assembly. The adhesive is then cured.
