Fabrication of porous metal cables

More stable superconducting cable can be achieved by improving the cooling. The best way to improve the cooling may be to increase the cooling surface. To do this we tried to fill the grooves of a Rutherford type cable with porous metal. Because the Rutherford type cable is used in lengths of several hundred meters to make a magnet, it is necessary to develop a reliable process to make the porous metal volume. This study was carried out to develop a reliable process for porous metal cables. Many revisions and trouble shootings were done, but not all the problems were solved. The next improvement can be carried out after analysing the test results of several typical porous metal cable samples.
