N2  - In this study we have performed computation and simulation to produce Spread Out Bragg Peak (SOBP) curve for proton, which is used to determine maximum ionization effect on the targeted tumor tissue and minimum effect to the surrounding healthy tissue. Computation and radiotherapy simulations are done on model of thyroid cancer. Tumor tissue is at a depth of 11.2 mm and has a thickness of 14 mm covered by three normal tissue, i.e. skin with a thickness of 1.2 mm, adipose tissue with a thickness of 4 mm and muscle tissue with thickness of 6 mm. The thyroid tissue is irradiated with 19 proton beams with energies ranging from 36 MeV to 54 MeV to cover the entire area of the tumor and will produce 19 Bragg curve. Computation is done to obtain appropriate weighting factors for each of the Bragg curve which then can be used to determine the number of protons for each beam in order to obtain the desired ionization effect.
