In neutron experiences at J-PARC MLF, neutron beams from the neutron source provide neutrons which have wide energy and which also contains unnecessary energy neutrons in the neutron experiences. These unnecessary neutrons are observed as background noises. Especially T0 burst (Time Zero Burst) which is neutron beams' components right after emitted from the neutron source affects neutron experiments, therefore the T0 burst must be removed before arriving at samples. T0 chopper is one of the devices to remove the T0 burst. High-durability T0 choppers is developed to extend maintenance periods in MLF in recent years and the high-durability T0 choppers have worked for multiple beamlines since 2019. A device control software framework: IROHA2 is used in MLF. IROHA2 enables us to collect device data automatically, operate devices remotely, control multiple devices comprehensively and so on when experimental devices connect to IROHA2. In this year, we designed and wrote communication programs to connect high-durability T0 chopper to IROHA2 and installed the programs in the T0 chopper and IROHA2 respectively. By installing these programs, we expect that the programs enable us to operate the T0 choppers stably and deal with some trouble flexibly. An outline about the control system for high-durability T0 choppers will be presented.
