  1. Heavy Ion Laboratory Warsaw University Jarosław Choiński

  2. Cyclotron • K=160 (up to 400 MeV of 40Ar) • Ion source: ECR, 10 GHza new source is going to be instaled soon • Extraction: stripping

  3. 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.

  4. Experimental Hall @ HIL
