With the newly built neutron wall on the compact spectrometer for heavy ion experiment (CSHINE), the n-n correlation function in the reactions of 124Sn + 124Sn at 25 MeV/u has been measured. The cross talk effect is corrected using a detailed Geant 4 simulation. The n-n correlation function has been fitted by LL model assuming a Gaussian source. the n-n scattering length and effective range (f0nn, 0dnn), as well as the reduced space-time size R(0) of the neutron emission source are simultaneously extracted as (18.9-1.2+1.3 fm, 1.9-1.0+1.3 and 4.12 ± 0.12 fm respectively. The results demonstrate the potential to pin down the charge symmetry breaking of nuclear force with femtoscopy correlation at improved resolution, and highlight the perspective of the future studies on isospin dynamics in heavy ion reactions.
