| MOPWA006 | Core-Halo Limit as an Indicator of High Intensity Beam Internal Dynamics | 86 |
|
||
|
The dynamics of high-intensity beams is mainly governed by their internal space charge forces. These forces induce emittance growth and halo generation. They contribute to shape the beam density profile. As a consequence, a careful analysis of this profile can help revealing the internal dynamics of the beam. This paper recalls the precise core-halo limit determination proposed earlier *, then studies its behavior through a wide range of beam profiles and finally shows its relevance as an indicator of the limit separating the two specific space charge field regimes of the core and the halo.

| MOPWA007 | The SARAF-LINAC Beam Dynamics | 89 |
|
||
| SNRC and CEA collaborate to the upgrade of the SARAF Accelerator to 5 mA CW 40 MeV deuteron and proton beams (Phase 2). This paper presents the beam dynamics in the reference design of the SARAF-LINAC (from the 4 m long 176 MHz RFQ to the HWR Superconducting linac’s end). The beam losses, mostly in longitudinal direction, estimated from error studies, are compared with acceptable losses defined for hands-on maintenance. | ||

| MOPWA008 | Status of TraceWin Code | 92 |
|
||
|
Well known in the community of high-intensity linear accelerators, the transport code TraceWin * is able to simulate a beam from the source to the target using either simple linear model or multiparticle simulations including 2D or 3D space-charge. Continuously developed at CEA Saclay since 15 years, it is today the reference code for projects such IFMIF, ESS, MYRRHA, SPIRAL2, IPHI … The accuracy of his predictions associated with an original and powerful GUI and its numerous features have made its success, with a community of 200 users worldwide. It is now used on a larger perimeter that its initial skills. The aim of this paper is to summarize the TraceWin capabilities, including implemented last ones.
