Nuclear emulsion is a three dimensional tracking detector with
sub-micron resolution. Thanks to its high spatial resolution, emulsion
can detect short-length low energy tracks and measure track angle
precisely in neutrino/hadron interactions. Moreover, the emulsion has 4
pi solid angle acceptance (it's also useful to measure low energy
tracks) and can use target materials flexibly, not only carbon and iron,
but also water. These detector capabilities of nuclear emulsion are
suitable to measure neutrino/hadron interaction precisely and therefore
it is used in NINJA experiment and EMPHATIC experiment to reduce the
systematic uncertainties from neutrino cross-sections and neutrino flux
in current and future neutrino oscillation experiments.
In this talk, I will talk the latest developments in nuclear emulsion
technology and the status/future prospects of NINJA and EMPHATIC.
