Sensitive High-Resolution Ion Microprobe (model: SHRIMP-IIe/ MC) was installed at the Ochang center of KBSI in 2008 and it is mainly applied for the analysis of uranium-lead isotope age dating of heavy minerals. SHRIMP, which can measure the isotope ratio for micro-areas of surface in solid materials, has been operated for researches on various fields of environmental, geologic, and planetary sciences.
The first High-Resolution Secondary Ion Mass Spectrometer in the Republic of Korea, manufactured by Australian Scientific Instruments(ASI), Model: SHRIMP lle/MC
- Primary Ion: $\mathrm{ Cs^+}$, $\mathrm{ O_2^-}$
- Mass Range: 6 to 300 amu
- Detection Limit: ~1 ppm with 10,000 mass resolution and 50% transmission
Korea Basic Science Institute is one of national user-facility center and it has a policy for use and share of each instrument, which means all outside users need to cover a certain portion of the total maintenance cost. Then, there are several kind of fee schedules (see below links). Also we have a global scientist invitation program. too.
- First, SHRIMP collaborative research: As a routine protocol for SHRIMP collaboration research, users need to submit the proposal: just about one-or-two-pages-proposal including the background and aim of your SHRIMP work and the number of specimens. Proposal can include any map, diagram or references if necessary. Detail plan for publication using these SHRIMP data is very critical (To mention the name of target journal is recommended). Also a CV of main investigator need to be included. Call for proposal is open twice a year (May and November), but you may send the proposal anytime, then it will be submitted to very next call.
- For collaborative research, the fee schedule is as follows; a) if you are coming to use SHRIMP directly, the cost of U-Pb dating is 800,000 KRW per 24 hours. b) if you just want to send mineral grains and ask us to analyze age datings, the cost is 1,500,000 KRW per 24 hours. And, extra 250,000 KRW will be charged for one mount preparation and SEM imaging.
- Publication using data from SHRIMP collaborative research is mandatory. If the result should be confidential, the commercial service should be chosen.
- Second, commercial service. It does not require any proposal and reviewing process. It is based on first-come-first-serve policy. In case of academic research, the cost by user is 1,400,000 KRW per 24 hours and the cost by KBSI staff will be 2,000,000 KRW per 24 hours. Also, extra 250,000 KRW will be charged for one mount preparation and SEM imaging. For a non-academic user, the cost by user is 1,800,000 KRW per 24 hours and the cost by KBSI staff will be 2,700,000 KRW per 24 hours. Also, extra 250,000 KRW will be charged for one mount preparation and SEM imaging.
- Last, global scientist invitation program. This program opens first quarter of each year. This program covers ~5,000,000 KRW per year to the each foreign scientist for air-travel fees and cost of instruments. Each year 8 to 12 scientist (for all 13 big and leading instrument of KBSI. SHRIMP is one of 13 instruments) can receive the funding from this program, which means that it is a sort of competitive situation.
- Applied from January, 2022, all analysis by KBSI staff (both collaborative research and commercial service) is limited less than five days in each month due to lack of staff in SHRIMP laboratory.
During 24 hours, 70 spot analysis for U-Pb dating are available, which is for 2 to 3 crystalline rocks or one detrital specimen.
