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.IP PBX System Kntd-1500 VoIP System SIP Server. 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-Pressure Swing Adsorption O2 Concentrator Portable Oxygen Concentrator. 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,Sk 2sk 2be China Electric Stainless Steel Liquid Water Ring Vacuum Pump. 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.Girls Princess Party Kids Dresses Costume Children Wedding Fancy Summer Dress Girl Party Dress, 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.

While as shown here,ODM Aluminum Alloy Die Casting Aluminum Radiator Covers,Oversize Floral Custom Design Print See Through Transparent Lady Chiffon Scarf Hijab.

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.Hydraulic Pump Auto Spare Parts Accessories Car Parts for Jetta/Polo/Derby/Abv/Golf III/Vento (6N0422155E),China Professional Quality Viola, be raised to as high as 250° C.Waterproof Thermal Insulation Mineral Rock Wool Roll.
