Abstract：
The LPT (Lanzhou Penning Trap) is under construction and its task is to perform direct mass measurement of fusion-evaporation residues and if possible for heavy isotopes. Detailed simulations have been done for a good understanding to the ion's movement and mechanics in the trap. The optimization of the LPT is also performed based on the simulation. With a scale of 0.5 mm per grid used in the simulation and many other limitations a highest mass resolution has been achieved to be 1.9×10^－5. An unexpected behaviour in the simulation related to magnetron motion has been found.
