For the open use of MLF neutron source, robustness (senses including tolerance, stability, acceptable outer affairs) of neutron devices against power noise must be estimated for surely acquition of neutron experimental data. For this purpose, we measure the groundline and power-line shape synclonized with many events, such as crane, chopper, neutron shutter and them on. This data is very usable to solve some accident, such as shutter keeping close. In this presentation, we will show some our solutions.
