                  September 2 - 5, 1998

                   FIRST ANNOUNCEMENT

Organized by
Saint-Petersburg State Technical University (SPTU),
A.F.Ioffe Physico-Technical Institute (PTI), RAS.
Sponsored by the International Committee for
High-Energy Spin Physics Symposia.

   -------------------------------------------------------------

The Low Energy Polarized Electron Workshop, 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  SPIN98
proceedings.  Informal  presentations  and  discussions will also be
scheduled.

--------------------------------------------------------------------

Topics will include:
Physics of Polarized Electron Photocathodes
- bulk ( optical orientation, high polarization, electron
  transport, depolarization)
- Band Banding Region phenomena
- NEA, high quantum efficiency, lifetime.....
New structures, fabrication and cleaning techniques.
Charge limitation.
Polarized Electron Guns. Status reports, new gun designs.
RF guns. Helium afterglow guns. High average current/ high
brightness current extraction... Helicity correlated
emission-asymmetries.
Low-Energy Polarimeters (Mott detectors, spin-dependent
absorption and transmission, spin-dependent surface current...).
Related Technical Issues

--------------------------------------------------------------------

Updated  information on the  Workshop can be  obtained by consulting

Registration fee

The registration fee  is US $100. The  registration fee will cover a
part of the participation in the social program, the proceedings and
Welcome reception.

The Workshop site:

State  Education Center  of St.  Petersburg. This  modern conference
center   has  well   equipped    conference    auditoriums  for oral
presentations, rooms for poster sessions, all necessary audio/visual
equipment, computer visualization interfacing, real-time translation
capability,  document copying  facilities, etc.  The Center 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.
