The last few months have been challenging, with not many news from the labs. However, the ever-growing international ion trap company population has been very successful in funding, awards and press coverage. We'll try to follow this rapid evolution, but for those who need their information faster, do not hesitate to subscribe to our Twitter account @tipicqa which closely follows @Ion_busters and other fore-front ion trappers.

Dear all,
The last few months have been challenging, with not many news from the labs. However, the ever-growing international ion trap company population has been very successful in funding, awards and press coverage. We’ll try to follow this rapid evolution, but for those who need their information faster, do not hesitate to subscribe to our Twitter account @tipicqa which closely follows @Ion_busters and other fore-front ion trappers.

On Thursday, 25 June 2020, Peter Toschek, one of the pioneers of ion trapping, has passed way. Peter Toschek has demonstrated laser cooling of ions in 1978, and observed the first individual ions in 1980. He has been very present in the ion trapping community for many decades. For his many important contributions, Peter Toschek was awarded the Herbert-Walther Award in 2015. More
