Production of titanium ion beams in an ECR ion source

2002

Abstract Intensive highly charged Ti ion beams were successfully produced in the 14 GHz ECR ion source at the Accelerator Laboratory, University of Jyvaskyla (JYFL). The Ti beams were produced using the MIVOC technique, i.e. by allowing the vapor of an organic compound containing titanium to diffuse into the ion source at room temperature. After optimizing the source parameters the intensity of the 48 Ti 11+ ion beam reached a value of 45 μA.

Production of a magnesium ion beam using the MIVOC method

1996

Abstract We report the successful production of multiply charged Mg ion beams at the Jyvaskyla ECRIS using a magnesium compound, magnesocene. The compound was placed in a separate vacuum chamber connected to the second stage of the 6.4 GHz JYFL-ECRIS. From there the vapour of the compound was allowed to diffuse into the source at room temperature. After a brief optimizing procedure the intensity of the 24 Mg 5+ beam was measured to be 11.8 eμA.

Utilisation of a sputtering device for targetry and diffusion studies

2004

A novel device for versatile sputtering applications is described. The apparatus design is realised for fulfilling the demands of both nuclear physics experiment target production and serial sectioning in solid-state diffusion studies with radiotracers. Results of several tests are reported, characterising the devise performance in these two differing applications.

First intense isotopic titanium-50 beam using MIVOC method

2012

Abstract An organometallic compound isotopically enriched in titanium-50 has been successfully used for the first time to produce intense ion beams with an ECR ion source by means of the MIVOC method. After some fruitful tests performed with compounds produced at IPHC Strasbourg with natural titanium, enriched organometallic titanium compound was produced successfully, beam extracted from ECR ion sources and accelerated through a K = 130 MeV cyclotron to an energy of 242 MeV. This isotopic 50 Ti 11 + beam was used for the first time in three week-experiment with typical MIVOC stable operating conditions. After optimization, up to 19.4 μA of titanium-50 in charge state 11 + could be extracte…
