PAST        : The seminars used to start at 10 am in SR03 at DESY in Zeuthen. There would normally be a common breakfast and paper discussion till around 10:30, when the presentation starts.

PRESENT : The seminars now start at 10.10 am in SR05 at DESY in Zeuthen. There is a common breakfast and casual discussion until around 10:30am, when the presentation starts.

The AP seminars are currently hybrid meetings

  • On demand, one Friday of every month could be dedicated to a journal club rather than a seminar; please see Journal Club for more details.
    • If Zoom-only: The Zoom room opens at 10:10 for a meet & greet with the speaker
    • If hybrid: Come talk to the speaker at 10:10 in the SR or the terrace outside
  • The seminar talk starts at 10:30am
  • The talk length is suggested as 40-45 minutes, not counting the discussion time
  • Join the seminar zoom meeting:
  • The meeting is password protected. The password is shared in the email announcement. If you did not receive it, contact the organisers.
  • If the speaker allows, the slides will be posted to the indico page or shared via email.
  • We can record the seminars if this is requested beforehand (at least one week before the seminar). For these seminars, during the event, photos or films will be taken for internal or external publication in the name of DESY. If you do not want to be recorded, you still can participate online and switch your camera and microphone off. Note that we will not record any questions that take place in the time after the talk.

For questions or speaker suggestions please contact:
