Due to the cancellation of many events this year, the organisers of ECTI and NACTI have agreed to shift the calendar by one year, so that ECTI will be held in 2021 and NACTI in 2022. More details soon to come. Our well-known training school in Les Houches is open for pre-registration (see below). We cross our fingers that January in Les Houches will be on-site and in-snow!






Dear all,
due to the cancellation of many events this year, the organisers of ECTI and NACTI have agreed to shift the calendar by one year, so that ECTI will be held in 2021 and NACTI in 2022. More details soon to come.
Our well-known training school in Les Houches is open for pre-registration (see below). We cross our fingers that January in Les Houches will be on-site and in-snow!
