The Warsaw IGISOL
Contact person: A. Wojtasiewicz
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.
