A large area position-sensitive ionization chamber for heavy-ion-induced reaction studies

A large area position-sensitive ionization chamber with a wide dynamic range has been developed to measure the mass, charge and energy of the heavy ions and the fission fragments produced in heavy-ion-induced reactions. The split anode geometry of the detector makes it suitable for both particle identification and energy measurements for heavy ions and fission fragments. The detector has been tested with α particles from 241Am–239Pu source, fission fragments from 252Cf and the heavy-ion beams from the 14UD Mumbai Pelletron accelerator facility. Using this detector, measurements on mass and total kinetic energy distributions in heavy-ion-induced fusion–fission reactions have been carried out for a wide range of excitation energies. Results on deep inelastic collisions and mass–energy correlations on different systems using this detector setup are discussed.
