St.Petersburg, Russia, September 2 - 5, 1998

E-mail: LE98@spes.stu.neva.ru

The Low Energy Polarized Electron Workshop ( LE98 ), organised by Saint-Petersburg State Technical University (SPTU), A.F.Ioffe Physico-Technical Institute (PTI), RAS and Sponsored by the International Committee for High-Energy Spin Physics Symposia, to be held just prior to the SPIN98 13th INTERNATIONAL SYMPOSIUM ON HIGH-ENERGY SPIN PHYSICS (Protvino, Russia).The workshop will follow an interdisciplinary approach, which has proven fruitful in past workshops. Contributions from all areas of research will be welcomed. Participants may present papers, which will then be published in the LE98 proceedings. Informal presentations and discussions will also be scheduled.

The updated information can be found in the WWW home page of the SPIN98 Symposium

* NO FIGURES ARE ALLOWED

* The first line includes the title ( in upper-case letters, 14 point size ).

* Next line: author's names ( first, middle initial and last names ).

The presenting author's name should be underlined. ( 12 point size letters )

* Next line: author's affiliation(s). ( 12 point size letters )

Venue

The Workshop will be held at the State Education Centre of St. Petersburg. This modern conference centre has well equipped conference auditoriums for oral presentations, rooms for poster sessions, all necessary audio/visual equipment, computer visualisation interfacing, real-time translation capability, document copying facilities, etc. The Centre also has modern hotel lodging and restaurants. It is a secure and safe facility and it includes its own medical clinic. It takes about 15 minutes by Metro (U-train) to downtown.

The Workshop will be conducted in English.

The weather in St. Petersburg at the beginning of September is mostly fine. The temperature is usually about 15 C. A light coat or a sweater may be needed as well as a raincoat and an umbrella.

You should present to the Organizing Committee all necessary information for visa requests for you and accompanying persons by filling the Registration Form attached. Invitations will be sent upon registration form is received.

Only roubles are officially acceptable for any payments, including SEC Hotel. So, it is necessary to change currency (US dollars preferable) in any Bank or exchange office in St. Petersburg. Most major credit cards (VISA, MASTER CARD) are accepted in many St. Petersburg banks and hotels ( in particular in hotels "Moskva" and "Oktyabrskaya"). Credit cards are also accepted in several (expensive!) restaurants and shops. AMERICAN EXPRESS credit cards are less widely accepted but there is an American Express office where travelers checks may be cashed.

The registration fee is US $100. The registration fee will cover a part of the participation in

the social program, the Proceedings, Welcome reception and transportation for the Workshop

events. The registration fee does not include accompanying persons' social program costs and

the Conference dinner (this will be arranged for separately at the Workshop). The cost of the

Conference dinner per person is US $30.
