abstract = {<p style="text-align: justify;">We consider a second order singularly perturbed boundary value problem, of reaction-convection-diffusion type with two small parameters, and the approximation of its solution by the $hp$ version of the Finite Element Method on the so-called $Spectral$ $Boundary$ $Layer$ mesh. We
show that the method converges uniformly, with respect to both singular perturbation parameters,
at an exponential rate when the error is measured in the energy norm. Numerical examples are
also presented, which illustrate our theoretical findings as well as compare the proposed method
with others found in the literature.</p>},
