A gas laser tube assembly includes a gas laser tube having ends, optical elements each vacuum-tightly closing off a respective end of the gas laser tube, each of the optical elements including a washer-shaped ceramic flange and a terminating plate being transparent to laser radiation and thermally matched to the ceramic flange, the ceramic flange having an outer rim joined to the gas laser tube and a central beam passage opening formed therein, and the terminating plate having two base surfaces, and glass solder connecting the terminating plate to the ceramic flange with the terminating plate covering the beam passage opening and projecting beyond the ceramic flange with at least one of the base surfaces thereof and a method of manufacturing the same.

A traveling wave tube having a helical delay line has a plurality of dielectric holding rods for supporting the delay line relative to a vacuum envelope. The holding rods are firmly adhered to the delay line and the envelope by means of solid-state reactions.

A gas discharge display tube, which has a rear tube wall with parallel extending cathode strips mounted thereon characterized by the cathode strips being mounted by each strip having a pair of spring plates slidably received on pins which are fused into the rear wall of the tube. Preferably, each of the strips has a box-like cross section for slidably receiving the spring plates so that the strip can be shifted along its length on the pins. In addition, the pins for adjacent strips are offset from each other so that the pins are aligned in two rows at each end of each of the cathode strips.
