A loop heat pipe (LHP) is an effective method to satisfy the requirement. JAXA has been developing a small LHP for space application. As part of the development and to better understand LHP operation, visualization of the working fluid using neutron radiography was conducted. As a result, much significant information, such as the behavior of the liquid at startup and dryout behavior in the primary wick, was observed. This information contributes greatly to the improvement of LHP design and the establishment of a numerical simulation model.
