  We study the spaces of Poisson, compound Poisson and Gamma noises as special
cases of a general approach to non-Gaussian white noise calculus, see
\cite{KSS96}. We use a known unitary isomorphism between Poisson and compound
Poisson spaces in order to transport analytic structures from Poisson space to
compound Poisson space. Finally we study a Fock type structure of chaos
decomposition on Gamma space.
