Conclusions

• The Bucharest Tandem Accelerator Small Scale
  Facility part of the European Infrastructure
• Complementary to Large Scale European Facilities
• More classical directions, which can still lead
  to important contributions to the field
• Ideal places for educating young scientists they
  go through all stages of an experiment and really
  achieve the desirable skills needed for future
  LSF groups
• An appropriate place for developing instruments
  or experimental methods intended for a LSF
• A correct balance between participating at
  experiments at LSF and developing an in house
  scientific program
