摘要： APPARATUS FOR ASSEMBLING A MULTIPLE ELEMENT TYPE ELECTRON GUN STRUCTURE EACH OF THE ELECTRON GUN UNITS COMPRISING FIRST TO FIFTH GRID ELECTRODES ARRANGED IN SUCCESSION ALONG THE PATH OF TRAVEL OF AN ELECTRON BEAM EMITTED FROM A CATHODIE ELECTRODE, OPPOSING ENDS OF THE THIRD AND FIFTH GRID ELECTRODES HAVING PROJECTIONS WITH A DIAMETER SMALLER THAN THE INNER DIAMETER OF THE FOURTH GRID ELECTRODE WHICH PARIALLY RECEIVES THE PROJECTIONS. THE ASSEMBLING APPARATUS INCLUDES SLOTTED SPACERS ENGAGING THE PROJECTIONS AND OTHER ELECTRODES TO ALIGN THE VARIOUS DLECTRODES. A CENTRE ROD, VARIOUYS HOLDERS AND MENS TO APPLY A LONGITUDINAL COMPRESSIVE FORCE ARE PROVIDED TO INSURE ACCURATE ALIGNMENT AND INTIMATE CONTACT OF THE GUN ELEMENTS DURING THE BONDING OPERATION.
