  The well-known moving mirror trajectory corresponding to black hole shell
collapse scenario (BHC) appears to produce an infinite amount of energy. By
changing the final velocity of the BHC mirror from the speed of light to a free
variable $\xi$ a new mirror trajectory was found. This modified BHC mirror
produces finite energy and emits thermal radiation. In the limit of $\xi \to c$
the BHC mirror is restored. In this thesis, the energy and particle production
of the modified BHC mirror, as well as the correlations in its radiation, are
presented.
