The time-of-flight spectrometer for heavy ions PISOLO

A time-of-flight spectrometer with magnetic focusing has been installed at the Laboratori Nazionali di Legnaro. The spectrometerʹs length is 3.6 m and allows for high-resolution time-of-flight measurements. Magnetic focusing is accomplished by two quadrupole doublets. The spectrometer is connected to a sliding seal scattering chamber rotating over a large angular range. Micro channel-plate detectors for start/stop signals and an ionization chamber for ΔE–E measurements at the focal plane, are used. The setup provides a maximum effective solid angle ΔΩ=2.8 msr, and is dedicated to the study of quasi-elastic reactions between heavy ions; in particular, it has already been used to investigate near-barrier multi-nucleon transfer processes.
