A grant-in-aid project on the database development for He II-cooled superconducting magnet system design has been going on as a 3-year project. Many big projects on He II cooled superconducting magnets and cavities have been planned and are under construction around the world. He II systems consist of many specific technologies such as helium heat transfer coefficients under pressurized and saturated superfluid helium conditions, cooling characteristics in micro channels, Kapitza resistance between the surface of heat exchanger, helium pumping techniques, in situ measurement of temperature, pressure under high magnetic fields, and so on. The four organizations including university and national institutes started their collaborative research on this project to develop a convenient and useful database system. Two activities are going on: The first is to pick up the related papers already published in journals and proceedings in cryogenics and superconductivity fields from 1970. The second is to carry out the original experimental researches on He II technologies to obtain new data and to obtain more accurate and reliable data. As for the first sources, we have already picked up about 1, 000 papers and have carried out several experiments. This paper describes the present situation on this research project on the He II database and future plan.
