Dr Megumi HIROTA
Naval Ship M&UEP Research Committee, NPO
Dr. Hirota joined Technical Research and Development Institute, Ministry of Defense, Japan, (then Japan Defense Agency) in 1979, and was appointed to the Chief of Magnetic Detection Research Section in 1989. Her research was on magnetic detection using SQUID and ship UEP signatures control. In 2010, she retired from civil service while she was assigned as the Deputy Director, Naval System's Development Division, TRDI. In 2012, She established with a few retired officers Naval Ship Magnetic & UEP Research Committee (NMURC), a Non Profit Organization, for new resaeach theams and from 2017 she is the representative.
POSTER: High Temperature Superconducting Cable Application to Ship Magnetic Deperming
The requirements of ship magnetic deperming are the intensity and the space (volume) of the magnetic field imposed on to the ship. Because of the large size of the ship to deperm, this volume consists of dimensions greater than 200 m in length and by 40 m in width and height. We studied the flat seabed coil for ship deperming and reported at UDT2018, which is the coil design with a bundle of round core cables wound by ReBCO (: Rear-Earth Barium Cupper Oxide) tapes, operating at 50K. This time we present a survey and study on other high temperature superconductors such as BSCCO (: Bismuth Strontium Calcium Cupper Oxide) and MgB2 for the same deperming coil requirement.
