We present a detailed discussion on the hadronic production of \$\Xi\_cc\$ at
a fixed target experiment at the LHC (After@LHC). It is produced via the
channel \$Proton + Proton\to\Xi\_cc+X\$, whose subprocesses include
\$g+g\Xi\_cc +c +c\$, \$g+c\Xi\_cc+c\$, and \$c+c\to
\Xi\_cc+g\$. The \$\Xi\_cc\$ can be produced via a binding diquark first and
then by grabbing soft light-quarks or gluons. Both two diquark configurations
\$(cc)^3S\_1\_\bf3\$ and \$(cc)^1S\_0\_6\$ have sizable contributions
to \$\Xi\_cc\$ production. We show that large number of \$\Xi\_cc\$ events can be
generated at the After@LHC, whose total production cross section is larger than
that of SELEX by about thirty-five times. It is even possible to study the
properties of \$\Xi\_bc\$. That is, about \$8.3 10^6\$ \$\Xi\_cc\$
events/year and \$1.8 10^4\$ \$\Xi\_bc\$ events/year can be generated when
the integrated luminosity equals \$2\$ fb\$^-1\$/year. Thus, in addition to the
hadronic experiments SELEX and LHC itself, the After@LHC can also provide a
useful platform for studying the baryon properties and has its own advantages.
