40th anniversary publication

07.05.2025

This year, the ATT turns 40. The organizing team has come up with something special: a free special issue for the celebration.
It includes a look back at ATT's history, statements from visitors, anecdotes and stories from exhibitors, and numerous reports on special ATT topics. We hope you enjoy reading it.

The issue will be distributed free of charge to ATT visitors at the entrance (only one copy at a time). Once it's gone, it's gone! Afterwards, the issue will also be available for download from this website.

We thank everyone who made this issue possible!
