Notes:
Laser ion source (LIS) is the most intense source of highly charged ions to fill the synchrotron rings in a single turn injection mode. For this reason LIS is used for ITEP TerraWatt Accumulator (TWAC) facility aiming at the production of TerraWatt power level (100 kJ/100 ns) of intense ion beams. Total current density, charge state distribution, and emittance of carbon ion beam generated by the 5 J/0.5 Hz rep-rate CO2 laser were measured at the exit of the source. A low energy beam transport line (LEBT) consisting of Einzel lenses and a buncher were used to match the source to 2 MV/2.5 MHz injector I-3. The C+4 ion beam with current up to 5 mA was accelerated by injector I–3 and about half of this amount have been injected into booster synchrotron. LIS was operated with rep-rate of 0.25 Hz during more than one year with few short breaks. Prolongation of intervention free period of LIS operation up to 3 months was achieved by using of CO2 laser gas mixture regeneration circuit. © 2002 American Institute of Physics.
