  We propose here a proposal to connect neutrino and energy frontiers, by
exploiting collimated muon beams for neutrino oscillations, which generate
symmetric neutrino and antineutrino sources: $\mu^+\rightarrow
e^+\,\bar{\nu}_{\mu}\, \nu_{e}$ and $\mu^-\rightarrow e^-\, \nu_{\mu}
\,\bar{\nu}_{e}$. Interfacing with long baseline neutrino detectors such as
DUNE and T2K, this experiment can be applicable to measure tau neutrino
properties, and also to probe neutrino CP phase, by measuring muon electron
(anti-)neutrino mixing or tau (anti-)neutrino appearance, and differences
between neutrino and antineutrino rates. There are several significant benefits
leading to large neutrino flux and high sensitivity on CP phase, including 1)
collimated and manipulable muon beams, which lead to a larger acceptance of
neutrino sources in the far detector side; 2) symmetric $\mu^+$ and $\mu^-$
beams, and thus symmetric neutrino and antineutrino sources, which make this
proposal ideally useful for measuring neutrino CP violation. More importantly,
$\bar{\nu}_{e,\mu}\rightarrow\bar{\nu}_\tau$ and $\nu_{e,\mu}\rightarrow
\nu_\tau$, and, $\bar{\nu}_{e}\rightarrow\bar{\nu}_\mu$ and $\nu_{e}\rightarrow
\nu_\mu$ oscillation signals can be collected simultaneously, with no needs for
separate specific runs for neutrinos or antineutrinos. Based on a simulation of
neutrino oscillation experiment, we estimate $10^4$ tau (anti-) neutrinos can
be collected within 5 years which makes this proposal suitable for a brighter
tau neutrino factory. Moreover, more than 7 standard deviations of sensitivity
can be reached for $\dcp = |\pi/2|$, within only five ears of data taking, by
combining tau and muon (anti-) neutrino appearances. With the development of a
more intensive muon beam targeting future muon collider, the neutrino potential
of the current proposal will surely be further improved.
