  报告一: Precision nuclear spectroscopy with slow and stopped RI beams at RIB 

  报告人:Prof. Michiharu Wada 

  Institute of Particle and Nuclear Studies, KEK 

  时间2月22日(星期三)上午10:00 

  地点:近代物理所工艺楼6楼会议室 

  报告摘要:We plan to perform comprehensive precision spectroscopy for the ground state properties of thousands of unstable nuclei that will be provided at RIBF. 

  There are three low-energy RI-beam sources at RIBF: GARIS, KISS, and BigRIPS+SLOWR where different types of gas catchers play important roles to provide universal slow or trapped unstable nuclei. A key spectrometer is multi-reflection time-of-flight mass spectrograph (MRTOF-MS) that can be used not only for mass measurements but also other unique purposes. Recently we performed precision mass measurements of trans uranium nuclei at GARIS-II. Some prompt report and future plans will be discussed. 

  报告二: Technical issues on gas catchers and multi-reflection time-of-flight mass spectrograph 

  报告人:Prof. Michiharu Wada 

  Institute of Particle and Nuclear Studies, KEK 

  时间2月22日(星期三)下午4:00 

  地点:近代物理所工艺楼6楼会议室 

  报告摘要:We discuss technical details on the rf ion guide gas catcher and MRTOF devices.
