THE FOURTH SYMPOSIUM ON A POWER SUPPLY FOR AN ACCELERATORS

December 17th- 18th 1998
OSAKA JAPAN

SECOND ANNOUNCEMENT
December 13th 1998

The fourth symposium on a power supply for accelerators will be held at Research Center for Nuclear Physics(RCNP), Osaka University. The symposium will starts at 13:30 on December 17th 1998 and will be closed at 16:30 on December 18th 1998. We send the program of this symposium and the participants' list.

You may see various topics not only for a power supply itself but also for related fields of a power supply in this program. You may also see various speakers and participants belonging not only to universities and institutes but also to private companies from the participants' list. These two features are characteristic of this symposium.

Even though planed deadline for participation is over, someone who want to take part in this this symposium are still welcomed. When you find our mistakes, please send e-mails to the Symposium Secretary, Dr. Shiro Ninomiya.

After this e-mail, we will not send another e-mail to you. You can obtain the newest information from the homepage of this symposium.
