Abstract :
The inverse Cerenkev acceleration (ICA) experiment is being performed an the Accelerator Test Facility (ATF) located at Brookhaven National Laboratory. This facility presently features a 50 MeV e-beam and a ~10 GW peak power CO2 laser. In the experiment 1.7 atm of H2 gas is used to slow the phase velocity of the light wave to match the electron velocity. The Cerenkov angle is 20 mrad and the interaction length is 20 cm. A peak energy gain of ~12 MeV is predicted assuming 5-GW of laser peak power delivered to the interaction region. An update of the experiment´s progress is presented
