Measuring the depolarization rate of a $^3$He hyperpolarized gas is a sensitive
method to probe hypothetical short-range spin-dependent forces. A dedicated
experiment is being set up at the Institute Laue Langevin in Grenoble to
improve the sensitivity. The status of the experiment is detailed in this
paper.
