Poster Session 2025
What? It's your chance to expose your work project and to present it within the bigger context of your experiment / department. You can make one on your own, or with a small group. Of course all students and supervisors are welcome to join us!
Please note that we only have 20-30 places available.
When? Thursday 24th July 2025 at 5pm to approx. 6h30pm
How? Please register on this event. Registration opens July 10th at 15h00
Where? Mezzanine of the Main Building- 500/1-201
More details:
Preparation of your Poster:
Posters can be as big as you like as long as they fit on the pannel. We recommend to print it in A0 (84.09 x 118.9 cm) or A1 (59.46 x 84.09 cm). The panels we use for the poster session are the same as the summer student notice board outside the Auditorium, so please just make sure it fits!
Where to print your Poster?
Your poster can be printed at the CERN Printshop. Once you have created your poster, you will just have to convert it into a pdf file and send it to the Printshop via the online submission form. You will then be informed when the poster has been printed and is ready for collection.
Note that if you want to print 2 or more copies you will have to provide a budget code (you will need to ask your supervisor for your group budget code).
The CERN Printshop is located on the ground floor of building 510 (opposite the Main Building): 510 R-007. The Printshop reception is open from: Monday-Friday, only by appointment in the morning and every afternoon from 13h to 16h30.
Please make sure that you submit your poster request during normal working hours, and not to leave it until the last moment! Note that for large conferences, the waiting list in front of you can be very long.
For those participants who have not sent the topic of their posters yet, please send it as soon as possible to the Summer Student Team!
We look forward to seeing you there, don't forget to invite your supervisor and colleagues to join us!

Chasing Time: Evaluation of Clock Stability towards LHCb Upgrade
Clock distribution within the current LHCb Timing and Fast Control (TFC) system relies on a custom architecture that lacks comprehensive stability evaluation across proposed alternatives. As the system prepares for an upgrade in Run 5, achieving reliable synchronization and monitoring at high precision becomes critical. This project focuses on developing and deploying an automated, modular testing infrastructure to evaluate the stability of different timing architectures. Cross-instrument measurements and runtime analysis techniques are used to assess signal behavior along the critical path. The results so far provide quantitative insight into clock phase behavior and hint the technological direction for the upgraded TFC system - opening the door of possibilities of subsequent testing and evaluation. - 17:36

Segmented Calorimeter Implementation for Faster Simulations of IDEA
The FCC-ee IDEA detector is currently in development. Due to high-granularity and large segment numbers, the two dual-readout calorimeters are memory intensive. This project focuses on allowing partial construction of these submodules in simulations while maintaining the true geometry and behaviour of the detector.

Previous ATLAS detector energy calibration studies concerned mainly with the low-mid energy range (pT<300 GeV), but the accuracy of the derived calibration on the higher energy was not accurately probed before. This project aims to inspect the precision of existing calibration in said energy region, particularly looking into the effects of different electronic gains used by the ATLAS calorimeter detector, and examine potential ways for its improvement. The outcome of this research will enhance future ATLAS measurements, such as single and di-photon production cross-sections, and improve jet energy calibration, which relies on accurate high-energy photon calibration.

The ability to distinguish between hard scatter (HS) and pile-up (PU) events is important for a large part of analyses of the LHC. Current pile-up detection algorithms employed by ATLAS are based on simple deep neural networks trained on high-level tracking information from the central region of the detector.
This project explores whether the inclusion of low-level tracking information can improve the performance of the neural network. Furthermore, we investigate the potential of neural networks with more advanced architecture, such as drop-out layers.
