he heavy-ion time-of-flight spectrometer HiToF
heavy-ion time-of-flight spectrometer called HiToF with magnet focusing accomplished by quadrupole triplet lens has been constructed at Beijing Tandem Accelerator National Laboratory, mainly for studies of multi-nucleon transfer reactions at energies near the Coulomb barrier. The spectrometer is equipped a rotating chamber with a diameter of 40 cm and can be rotated in a large angular range from -40 to 160. The length from target to the focal plane is 2.7 m, enabling high-precision time-of-flight measurements by two micro-channel-plate detectors with 1.9 m apart and typical time resolution of 120 ps. A multi-sampling position-sensitive ionization chamber for E-E measurement is placed on the focal plane, which offers Z/Z resolution of 1/50. The setup provides a maximum solid angle = 20 msr. An experiment of 32S + 90,94Zr at the beam energy of 135 MeV was performed to test the performance. The projectile-like ions were identified clearly with the mass resolution = 0.2 amu. Results show that the HiToF spectrometer is a powerful setup for studying the heavy-ion reaction mechanisms at low-energies.
