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.
