Future synchrotron light source using a 5-GeV energy recovery linac (ERL) is under proposal by our Japanese collaboration team, and we are conducting R&D efforts for that. We are developing high-brightness DC photocathode guns, two types of cryomodules for both injector and main superconducting (SC) linacs, and 1.3 GHz high CW-power RF sources. We are also constructing the Compact ERL (cERL) for demonstrating the recirculation of low-emittance, high-current beams using above-mentioned critical technologies.

Times Cited Count：13 Percentile：54.37(Optics)The charge states of fragment ions were measured for 1-MeV/atom C cluster ions penetrating a carbon foil of 2.4-
g/cm
thickness. Those ions were detected with a luminance plate detector monitored by a CCD camera. The detected ion signals were traced by coulomb explosion imaging technique, which enabled us to classify charge states of each fragment ion and spatial structure of a cluster ion on emerging from the foil. Using this technique, for the first time, we found that (1) the measured average charges of the fragment ions in a triangular structure are smaller than those in a linear-chain structure, and (2) the edge-position ions in a linear structure have the average charges greater than the middle-position ion. These experimental results are well supported by a recent theory on the cluster average charge.

The charge states were measured for the constituent ions of 1 MeV/atom C ions passing through a carbon thin foil. The constituent ions of C ions deflected by the deflection plates were detected with a luminance plate position detector monitored by a CCD camera. Since the detected ion signals contain the information of charge states and cluster structure, this measurement method enabled us to investigate the structure-dependent of the average charges in the cluster ions. The data clearly show that the measured average charges of C ions in a linear-chain structure are larger than those in a ring structure. Moreover we found that the edge-position ions in a linear structure have the average charges larger than the middle-position ion. These experimental results are well supported by a recent theory on the cluster average charge.
