Canted-Cosine-Thera (CCT) superconducting magnet is a promising alternative for normal-conducting magnets in compact accelerator systems such as large hadron colliders or particle therapy facilities. For the convenience of lattice design with CCT, we develop the CCT Simulation and Particle Tracking (CSPT) toolkit. It’s a program that can perform both simulations of the beam dynamic process within particle accelerators and basic electromagnetic harmonic analysis. The charged-particle tracking and electromagnetic calculation process can be accelerated by either CPU multicore or GPU parallel, with a maximum speed-up ratio of 457. The simulation result of the program is well consistent with Opera and COSY Infinity.

Due to the PB algorithm’s limited accuracy, a higher accuracy dose verification tool is a legal requirement for proton therapy. Therefore, we developed an automated treatment plan dose verification framework based on the Monte-Carlo (MC) algorithm .The MC beam model was derived from commissioning data and fed into our automated software. CT and treatment plan from TPS were input for the automated software. The developed tool was validated and compared with the PB algorithm of Pinnacle3 TPS for 85 prostate patients. The difference between the PB dose and the MC dose of our automated tool was evaluated using gamma analysis (3 mm/3%, and 2mm/2% criteria) and mean absolute errors. Although the result shows good agreement and the passing rate was about 95%, the difference of all the indices was found to increase as the degree of tissue heterogeneity increased. The MC dose has a higher MAE in CTV, and femoral head compared to the PB dose. The automated software can facilitate patient plan verification in institutions and be useful for other clinical applications.
