ICIS2021 Group photoThe ICIS’21 is the 19th event in a biennial series of conferences that are dedicated to Ion Sources and their applications. Recent conferences in this series have been held in Lanzhou (2019), Geneva (2017), New York, USA (2015), Chiba, Japan (2013), and Giardini Naxos, Italy (2011). The 19th ICIS was supposed to be held from September 19-24, 2021 in Victoria, BC, Canada, hosted by TRIUMF, Canada’s Particle Accelerator Laboratory. The International Advisory Committee (IAC) of ICIS’21 had to make the difficult decision to postpone the next in-person conference to 2023 and a smaller fully virtual conference hosted will be held this year, September 20-24. 


Whilst details are still being developed and finalised, TRIUMF will host a Zoom-based multi-day program over the same original dates. For poster sessions and the coffee breaks, we will create a virtual space in Gathertown to meet and discuss. The scientific program of the virtual ICIS'21 will offer plenary sessions of invited and contributed oral presentations and two Poster sessions will be arranged  as well. The scientific program will cover themes of the ion sources science and technology that are relevant to the production of ion beams for scientific research and for applications. ICIS traditionally addresses 

  • Fundamental processes in ion sources, plasma 

  • Production of high intensity ion beams 

  • Production of highly charged ion beams 

  • Negative ion sources 

  • Ion sources for fusion 

  • Polarized ion sources 

  • Radioactive ion sources and charge breeders 

  • Beam formation, extraction, transport, and diagnostics 

  • Applications of ion sources  

  • Key technologies for ion sources 


The host TRIUMF employs a unique accelerator complex, that comprises high intensity driver beams for secondary particle production and a world class rare isotope facility - ISAC. TRIUMF operates high intensity H- sources, several stable beam sources, and target ion sources for rare isotope beam production. Three charge state breeders, an operational ECRIS based charge state booster (CSB) and two EBIS based charge state breeder provided by the CANREB project and an operational device, developed for the TITAN facility, complete the ion source infrastructure. 


We look forward to welcome you ‘virtually’ in September 2021,
