The linac for the next generation electron-positron linear collider (NLC) will be comprised of nine thousand accelerator structures each requiring 207 ultra-high precision copper cells. The cost of building these nearly two million copper cells is expected to be as much as ten percent of the total cost of building the entire machine. In order to reduce the cost of manufacturing these copper accelerator cells, this project will apply adiabatic forming methods to replace the rough machining of accelerator cells. The adiabatic process can form exotic lightweight metals into shapes not possible with conventional presses. It requires little or no lubricants or cutting fluids and therefore, can eliminate or reduce cleaning and water disposal. Phase I will develop models and perform calculations required for adiabatically forming the cells. The calculations will be verified by developing prototype tooling and producing scale size cells.
Commercial Applications and Other Benefits as described by the awardee: The adiabatic forming process should be the technology of choice for producing the accelerator cells for the NLC. It is extremely fast (milliseconds) and uses 80 percent less energy than conventional methods.
