The IGISOL facility (Ion Guide and Isotope Separator On-Line) is constructed and installed on line with the cyclotron U200P. It is designed for the heavy-ion reactions and production of the radioactive beams to study of short-lived isotopes especially of the refractory elements.

The device consists of the mass separator, the ion source of the Ion Guide type, the helium pumping system and the detection set-up.

The main characteristics of the IGISOL are:

• Mass separator
  • Scandinavian type,
  • acceleration voltage 40 kV
  • analyzing magnet: 55 degrees of deflection,
  • mean radius of ion trajectories: 1500 mm
  • mass resolving power: 700 to 260 depending on helium pressure in ion source.
• Ion source
  • Ion Guide type (designed for HI induced fusion-evaporation reactions),
  • attenutation of plasma effect (“shadow method”)
• Helium pumping system
  • two Roots pump stands, each of about 4000 m³ pumping speed,
  • helium purification system (LN traps)
  • evacuation time of ions from helium chamber of the order of 10^-3.
• Detection setup
  • tape station
  • advanced time delayed system (beta, gamma-gamma, Ge, Si(Li), BaF₂ detectors),
  • mini-orange spectrometer.

The Warsaw IGISOL is a part of the EU Ion Catcher project.
