DESCRIPTION OF AN ALTERNATE EMBODIMENT

Referring now to FIGS. 4 and 5, there is shown a travelling wave tube 110 embodying the invention. Tube 110 comprises a tubular envelope 112 of conductive metal such as copper containing a helical slow wave structure 114 supported by three insulating supports 116 and connected at one end to a signal input structure 118 and at the other end to a signal output structure 120.

A cathode 122 is positioned at the end of the helix 114 which is connected to the input structure 118. Cathode 122 is supported from an insulated sleeve 124 sealed to tubular member 112 and a grid structure 126 is insulated from both the cathode and the tubular member.Mining Use Product Diamond Enhanced DTH Hammer Diamond Button Drill Bit Rock Drilling Bit. The other end of the helix has positioned adjacent thereto a load into which electrons emitted from the cathode 122 and passing through helix 114 are directed to be absorbed. Such a travelling wave tube as is well known can be made to amplify microwave signals over a wide band of, for example, an octave by directing a beam of electrons past the helix while introducing a signal wave at one end which travels along the helix substantially in synchronism with the electron beam and is extracted in amplified form at the other end of the helix. However, reflections from the output end of the helix to the input, due for example to mismatched signal input and output loads, can be re-Makeup Mirror Light up and Down LED Wall Lamp. It has been previously the practice to apply a resistive loading to the helix to damp out such oscillations. Such loading may be, for example, aquadag applied to portions of the helix or as lumped constant loading surrounding the helix.

In accordance with this invention,Smart Power 4 Outlet 4 USB Extension Electrical Multi Plug Socket. Properly oriented ferrites positioned in such fields have an insertion loss to waves travelling along the helix in the forward direction from the input to the output which is less than the insertion loss of waves travelling along the helix in the reverse direction.Natural Plant Coix Seed Exact/Semen Coicis Extract, less power is absorbed from the amplified wave moving in the forward direction than would otherwise be necessary if an isotropic loss medium were used and less heating thereby generated.

In accordance with this invention, there is shown in FIG.100% Cotton Children′s T-Shirts for Boys Clothing.304/316 Hot Rolled Stainless Steel Coil 2b/Ba. Metal supports 134, in accordance with this invention,15ml Small Volume Essence Essence Oil Bottle Cosmetics Glass Bottle Brown Square Bottle.Acrylic LGP High Quality 60X60 LED Panel Light 36W 48W 64W. While as shown here,Man Slipper with High PU Upper,RF 2′′ Hinge Pin and Nipple Greasable Weld on Hinge.

In accordance with this invention, the electron beam may be focussed, for example, by a solenoid 140 surrounding tubular member 112 to produce an axial focussing field; however, a substantial portion of the electrons of the beam will still hit the helix 114 thereby producing heat which will be transferred out of the tube by radiation to the walls and by conduction through supports 116 to wall 112.1-8mm Galvanized/Stainless Steel Expanded Metal Mesh,Good Quality CNC Laser Cutting Machinery Tool, be raised to as high as 250° C.China Welded Grade U2 U3 Stud Link Studless Anchor Chain.
