Performance of the heavy-ion magnetic spectrograph 'ENMA' on the kinematic correction

A magnetic spectrograph, named ENMA, has been sucessfully put into operation for heavy-ion reaction studies at the JAERI tandem accelerator. The spectrograph consists of two dipoles, a quadrupole and three multipoles arranged in the form of Q-M1-D1-M2-D2-M3.. The kinematic broadening has been well compensated for over the kinematics parameter range from k = -0.4 to 1.15 mainly with a quadrupole field produced by the multipole magnet M2. The energy resolution obtained as a function of the kinematic parameter k is consistent with the value estimated from the contributions due to the target effects, the beam emittance and the intrinsic energy resolution of the spectrograph.
