On 2016, we started a project to correct and analyze research achievements obtained with J-PARC MLF. Though there was a list of the achievement, it was not applicable to data processing for the analysis because the data format was NOT unified and dependent on the person. Hence, we define a sorting policy of the achievements first and re-collect the achievement even though it was already existing. Next, the achievements were compared with those of other facilities available online based on the quantity and quality analysis with the same index. Finally, the list and analysis results of the achievements of the MLF facility is now open in the web site and being updated every half a year.
Neutron imaging was used for the non-destructive observation of grease fluidity inside ball bearings after rotation testing. Two types of greases with different energy-saving properties were studied. Imaging revealed that adherence of the grease to the rolling elements varied depending on the grease type. This relates to the grease’s energy-saving performance, since adherence of the grease to the rolling elements affects resistance as the bearing rotates. Neutron imaging is a unique technology that enables non-destructive observation of grease fluidity inside bearings and could be an effective tool for developing future energy-saving greases.
