An important factor in the Accelerator Laboratory activity has been the extent of outside funding which we have been able to maintain at the level of 1996. A direct consequence has been an increase in the number of postgraduate students compared to previous years. The laboratory's research programme has concentrated on materials science and several new domestic and international co-operation projects have been launched during 1997. Further nuclear, applied, laser and molecular physics have been well represented.
The development of the Accelerator Mass Spectrometry (AMS) project has continued and will be in flight in 1998. The main technical developments have been the finalizing of the isotope separator upgrade and the planning and starting the installation of a helium ion source for the EGP-10-II accelerator. The technical projects have been realized by outside funding and by the laboratory's own investments.
Investigating lasers and the performance of laser spectroscopy have been continued, mainly using diode lasers in the red wavelength range. Also basic laser physical phenomena have been studied, examples of which are given in the supplementary Annual Report. Similarly to the previous years the laboratory facilities and equipment have been utilized for educational demonstrations to groups visiting the laboratory.
The activity in molecular physics has, historically, evolved around the Raman spectrometer. Several collaborative projects with research groups both in Finland and abroad are going on in the fields of spectroscopy of liquids, intermolecular forces, molecular modeling, optics and digital spectral analysis.
