In order to measure negative-ion temperature, the experimental result of the negative-ion recovery ratio from the two-laser photodetachment is usually fitted with the theoretical curve derived from the ballistic kinetic theory of negative ions. The particle-in-cell (PIC) code with a one-dimensional slab model has been developed to analyze the effect of the ambipolar electric field, which is neglected in the ballistic theory, on the negative-ion recovery. The preliminary results of the PIC simulation indicate that our PIC code is a useful tool for the analyses of the negative-ion recovery in the photodetachment.
