Production of metallic stable ion beams for GANIL and SPIRAL2
Abstract : GANIL has been producing many stable beams for
nearly 30 years. Constant progress has been made in
terms of intensity, stability and reliability. The intensity
for some stable metallic beams now exceeds or
approaches the pμA level at an energy up to 95 MeV/u:
1.14 pμA for 36S (65% enriched) at 77 MeV/u, 0.35 pμA
for 58Ni (63%) at 74 MeV/u. The presentation highlights
recent results obtained with 50Ti using the MIVOC
(Metallic Ions from Volatile Compounds) methods on the
ECR4 ion source. The Titanium beam was produced
using the organo-metallic compound Titanocene :
Cp*TiMe3. The synthesis of this metallocene compound
has been successfully performed by the IPHC-Strasbourg
from isotopically enriched 50Ti metal. Two tests have
been done with the natural Titanocene (48Ti) to validate
the new compound, and to qualify the intensity and beam
stability. The good results obtained led us to program the
Physics experiment in 2013, September and we have
produced a very stable 50Ti10+ beam at an intensity of
20μA for 300 hours. The Spiral 2 facility, currently of
installation, will provide gaseous and metallic stable ion
beams. The ion source choice for the commissioning of
the stable beams Q/A=1/3 is the ECRIS PHOENIX V2.
This ECRIS has been designed by LPSC Grenoble and
several tests of stable metallic beams have been realized
in this laboratory. The results for Nickel (58Ni19+) and
calcium (40Ca16+) are given.
