  The Weizsaecker-Williams transverse momentum dependent (TMD) gluon
distributions can be probed in the production of a hard dijet in semi-inclusive
DIS. This process is sensitive not only to the conventional but also to the
linearly polarized gluon distribution. The latter gives rise to an azimuthal
dependence of the dijet cross section and therefore can be distinguished from
the former. Feasibility study of a measurement of these TMDs through dijet
production at a future electron-ion collider shows that the extraction of the
distribution of linearly polarized gluons with a statistical accuracy of 5%
will require estimated luminosity of 20 fb^{-1} /A.
