  We study inflation driven by a slow-rolling inflaton field, characterised by
a quadratic potential, and incorporating radiative corrections within the
context of supergravity. In this model the energy scale of inflation is not
overly constrained by the requirement of generating the observed level of
density fluctuations and can have a physically interesting value, e.g. the
supersymmetry breaking scale of $10^{10}$ GeV or the electroweak scale of
$10^3$ GeV. In this mass range the inflaton is light enough to be confined at
the origin by thermal effects, naturally generating the initial conditions for
a (last) stage of inflation of the new inflationary type.
