Seminar: Multi-reflection Time-of-flight Mass Spectrographs

Title: Multi-reflection time-of-flight mass spectrographs 

Speaker: Dr. Peter Henry Schury (KEK Wako Nuclear Science Center, Japan)     

Time: 10:00am, Nov.19 (Tuesday), 2019 

Place: Meeting room on the 6th floor, Technique Building  

Abstract:  

The KEK Wako Nuclear Science Center operates several multi-reflection time-of-flight mass spectrographs (MRTOF-MS) within RIKEN’s Radioactive Ion Beam Factory. One is dedicated to measurements of very heavy and superheavy elements (SHE).  Another is being used with nuclei produced in multi-nucleon transfer (MNT) reactions. Others will soon be used with nuclei produced via in-flight fission at BigRIPS. In each of these, the device is used not only to measure masses. The MRTOF-MS which is focused on SHE allows for measuring alpha-decay half-lives in addition to masses. The device dedicated for use with MNT products enhances the capability for laser spectroscopy. The future devices at BigRIPS will allow for half-life measurements, particle identification, and beta-delayed neutron multiplicity measurements. The speaker will describe the design and operation of our MRTOF-MS, provide an overview of recent results, and explain how researchers have used them for measuring more than masses as well as future plans.
