The antiproton decelerator (AD) dedicated to atomic physics and related fields will start its operation in 1999 after three years since the termination of LEAR in 1996. It is therefore a good time to have a workshop on atomic physics with slow antiprotons and related fields to summarize the past, to have a common understanding of the antiproton facility, and to discuss various aspects and future of the slow antiproton science. The workshop will be held in Tsurumi near Tokyo and Yokohama three days in advance to the XXIst ICPEAC (http://power1.pc.uec.ac.jp/Sendai/) as a satellite meeting. The date and location is determined so that the attendees of the ICPEAC who are interested in the subject can easily join the Workshop on their way from Narita Airport to Sendai. The major topics of the workshop will be;

There will be a chartered bus service from Shinagawa Prince Hotel to Tsurumi Girl's High School in the morning and from Tsurumi Girl's High School to Shinagawa Prince Hotel in the afternoon during the Workshop .

The registration fee is Yen 20,000, which includes the abstract book, coffee during coffee break, and all the Social Program (for details, see below).

The registration fee for the accompanying person(s) is Yen 10,000, which includes all the Social Program.

Some financial support will be available for students and for invited speakers.

The registration desk will open at the Hotel on July 18 (Sunday) in front of the room where the Welcome Drink is served. The registration fee (Yen 20,000) must be paid at the desk. We can only accept Japanese Yen in cash. The scientific session of the Workshop will start on Monday morning.

A block of rooms are reserved at Shinagawa Prince Hotel near Shinagawa Station of JR with a special discount rate for the workshop. The hotel has a direct connection from Narita Airport by the limousine bus ( http://www.narita-airport.or.jp/airport_e/access_e/access_index.html ) Reservation must be made by June 10, 1999 with the reservation form attached below.
