Plasma Charge Current for Controlling and Monitoring Electron Beam Welding with Beam Oscillation
Electron beam welding (EBW) shows certain problems with the control of focus regime. The electron beam focus can be controlled in electron-beam welding based on the parameters of a secondary signal. In this case, the parameters like secondary emissions and focus coil current have extreme relationships. There are two values of focus coil current which provide equal value signal parameters. There...
متن کاملThe use of Electron Beam Welding in Turbomachinery Manufacturing
As demands for higher performance migrated from aircraft engines to land based gas turbines the need for EB welding came along also. The transfer of EB welding processes from relatively thin section components in aircraft turbines to land based aero derivative turbines is straightforward since the basic design and function of both aero and aero derivative components are the same or similar. How...
متن کاملFINAL-FOCUS OPTICS FOR THE LHeC ELECTRON BEAM LINE∗
One of the options considered for the ECFA-CERNNuPECC design study for a Large Hadron electron Collider (LHeC) [1] based on the LHC is adding a recirculating energy-recovery linac tangential to the LHC. First designs of the electron Final Focus System have shown the need to correct the chromatic aberrations. Two designs using different approaches for the chromaticity correction are compared, na...
متن کاملImproving Laser Beam Welding Efficiency
Laser beam welding is becoming widely used in many industrial applications. This paper reviews recent research conducted on the performance, potential and problems of thick section butt joint laser welding. Common defects that occur in laser beam welding with high power laser welding are discussed and possible solutions proposed. Methods of welding process efficiency improvement are analyzed.
متن کاملEffect of Backscattered Electrons on Electron Beam Focus
Using an induction linac, ETA-II, we are studying the interaction of a 2 kA, 6 MeV electron beam focused to a <2 mm diameter spot on high-Z foils. A focus shift was noticed when changing from 5 mil to 40 mil tantalum foil targets. This shift was subsequently attributed to the effect of a substantial fraction of the incident electron beam backscattering from the target, reducing the net beam cur...
