CIMAC will offer traditional 20 minute long presentations which will be complemented by Pecha Kucha presentations to mix up the congress program. Posters including a special timeslot during the breaks to present the poster are going to be part of the congress too. This main programme will be embedded in discussion panels, key note speeches, and plenty of networking opportunities.

Pecha Kucha Presentations

20 slides, each slide is shown for exactly 20 seconds, then the presentation automatically jumps to the next slide! This fast paced format focusses on just a few key points in the presentation and therefore sticks in people's minds particularly well.

The advantage for the author is that no paper has to be written. Presentations can therefore be submitted relatively easily. Only the abstract is enough to get the chance of a presentation slot. In addition, the slide set must be submitted before the congress.


Traditional presentations will once more be avaiable. 15 minutes for your presentation and an additional 5min for questions and answers afterwards. This detailed format gives you the opportunity to present new findings in detail.


The Poster Session will be avaiable to visitors throughout the entire congress. On top of that the programm will feature each poster with a special timeslot, so that the author may present his findings to the interested autdience in detail and can answer upcoming questions.

Due to that physical presence is mandatory for poster authors too.

Operators Perspective

We expressly invite you to submit papers that are of importance to operators. It is our aim to offer some sessions specifically for this target group. In particular, safety issues, ensuring the continuous availability of the systems, maintenance and regulatory issues are of importance here.
Looking at the industry from the customer's point of view will lead to new insights and solutions!

Best submissions and presentations at the 2023 event!

Three authors will again be selected to gain an award for their contribution to the CIMAC congress. Drawing your attention to the Congress 2023 Awards for three outstanding papers presented (Best Paper, President's Award, and Best Poster). Exciting prizes to be won, so here is encouraging all potential authors to put your best foot forward and compete amongst the best from the industry.
