A new method for calculating the neutron sensitivity of the slot-collimated fission detector system based on analytical formula is presented. The analytical formula of the neutron sensitivity was achieved through educing the numbers of fragments and the fragments acquisition probability of PIN detectors by the methods of integral and Taylor expansion. The neutron sensitivity was also measured on a D-T accelerator. The theoretical results derived from the formulas are consistent with the experimental ones with the deviation is less than 10%．
