Abstract :
The TASCC heavy ion facility produces beams at specific energies of 4 to 50 MeV/u. We report on the fine time structure of the beam, typically bunches of 150-500 ps FWHM, at a repetition rate of 31-62 MHz. Average beam currents range from 1 to 500 enA. The ratio between peak and dark current typically exceeds 5000:1, ideal for time-of-flight experiments. We also discuss measurements of absolute beam energy by bunch time-of-flight
