 note = {0000-0003-4555-1837, A fusion burning plasma is sustained by deuterium-tritium (DT)-born energetic alpha particles. Therefore, energetic alpha particles must be well confined. In a deuterium experiment, 1 MeV tritons are created by D(d,p)T reactions. 1 MeV triton is regarded as simulated DT-born alpha particles because their kinetic parameters are almost same. A study of 1 MeV triton confinement has been widely and intensively performed in fusion devices in order to understand alpha particle confinement. To understand 1 MeV triton confinement/loss in EAST plasmas, 1 MeV triton orbit analysis is performed in various plasma current (Ip) cases using LORBIT codes. It is shown that the number of lost tritons decreases with an increase in Ip. The number of lost tritons rapidly increases at 10−6 s; then, it is almost saturated at 10−5 s regardless of Ip. The pitch angle distribution of confined 1 MeV triton shows that tritons that exist in a wider pitch angle range can be confined in the higher Ip case compared with the lower Ip case.},
