Description

The third ACTS developers workshop will take place at CERN from the 26/09 through 30/09, following Berkeley (2019) and DESY/Virtual (2020)

The workshop will consist of:

2 days general talks, introduction and discussions
1 day general tutorial
1 day break-out for dedicated clients (ATLAS, key4hep, ...)
1 day allowing for spontaneously chosen topics

It will allow for remote participation, which will be supported also by video-recording of the contributions and morning/afternoon recap sessions that allow to follow up on questions/issues raised by attendees that - due to their home institute time zone - can not attend the sessions live, but rather through video recast.

Preparation Events:

1st Docathon: Aug 8, 2022 @ CERN
2nd Docathon: Sep 14, 2022 @ CERN

COVID19 restrictions: the at the time of the workshop given CERN COVID level restriction will apply, including a potential cancellation of the on-site meeting. We have booked big venues that would allow eventual necessary spacing of participants if permitted. In case of cancellation of the on-site meeting, we will try to hold at least parts of the workshop as a virtual meeting.

Letter of Invitation: If you need a letter of Invitation to the Workshop, please contact the organisers.,
