Heavy Ion Laboratory

Warsaw University

Jarosław Choiński


Cyclotron

  • K=160 (up to 400 MeV of 40Ar)

  • Ion source: ECR, 10 GHza new source is going to be instaled soon

  • Extraction: stripping


  • Total beam-on-target time: 2434 hours in 2006(about 2 600 hours/year – mean value in last 5 years)

  • About 1 200 hours of beam-on-target time in 2006 was used by international users.

  • All projects performed at HIL are evaluated by international Program Advisory Committee.
