IBERSIMS is built around an state-of-art Sensitive-High-Resolution-Ion-Microprobe (SHRIMP ) designed at the Australian National University’s Research School of Earth Sciences and built by Australian Scientific Instruments. The SHRIMP was installed at the CIC-UGR during May-June 2011, and was open to public access in September 2011
The SHRIMP is the model IIe/MC. It’s nickname is MaCarena
The primary beam system includes a duoplasmatron, for analyzing positive ions, and a Cs gun, for analyzing negative ions
The detection system is a multicollector equipped with (1) one high-efficiency ETP multiplier for single collection mode, (2) an array of five Sjuts multipliers, (3) an array of three Faraday cups
The stage can keep simultaneously two mounts. Another four mounts can be stored under vacuum in a separate chamber, and changed automatically when needed. The stage can be driven from a calibrated sample map to facilitate navigation through the mount. The stage can be programmed for long runs, overnight or longer
The auxiliary equipment includes:
(1)a facility for mount preparation, including megamounts (Ø = 35 mm) specially suitable for light isotopes (O, S, B, Li)
(2)a facility for sample documentation, including a optical microscope (reflected and transmitted light) and a ZEISS EVO-150 SEM equipped, among others, with a cathodoluminescence detector
The IBERSIMS staff currently consists of members of the Research Group RNM 302 of the Department of Mineralogy and Petrology:
Prof. Dr. Fernando Bea (fbea@ugr.es), Director and SHRIMP manager
Prof. Dr. Pilar Montero (pmontero@ugr.es), SHRIMP manager
D. Delia Ortega (delia@ugr.es) , Technician
D. Isabel Nieto García (c2620601@ugr.es), Technician
too short, isn’t it? Hopefully, we shall grow soon
