“…In this case the measurement was performed without the full potentials on the three GEL electrodes, and an un-normalised 4xRMS emittance from 600 to 700 mm.mrad was found. Simulation [7] predicted an emittance growth of a factor 1.5, while the experiments indicate a factor 2 -2.5.…”

A laser ion source using a CO 2 laser focused onto a solid target is under study at CERN for the production of high currents of highly-charged heavy ions, for possible use in the pre-injector for LHC. A new expansion and extraction layout was installed in this test facility, improving the alignment and making the target to extraction distance more flexible. A two solenoid beam transport system was studied for providing the matching of the beam to an RFQ. An electrostatic beam transport using gridded electrostatic lenses was designed and constructed as an alternative to a magnetic system. Results show an increased overall current transmission for the electrostatic case. Investigation of the laser parameters required for the production of 1.4x1010 Pb 25+ ions in a 5 µs pulse, has been performed using the TIR-1 laser facility at power densities up to 10 14 Wcm -2 for a focal spot size of 65 µm. The results of the latest scaling are presented.
