We consider a demonstration of the ionization cooling principle using 2.5-MeV protons interacting with an internal hydrogen target in the Integrable Optics Test Accelerator (IOTA) being constructed at Fermilab in the Advanced Superconducting Test Accelerator (ASTA) facility. We calculate the beam loss rates due to single Coulomb scattering, neutralization, and nuclear interactions. An estimate of the expected transverse ionization cooling rate and multiple-Coulomb-scattering heating rate is given. The longitudinal heating of the beam due to the negative slope of the stopping power and to energy straggling is also estimated.
