We take immense pride in continuing our legacy of bringing together and disseminating knowledge of accelerator science. Over the years, thousands of bright accelerator scientists and experts have been trained through the CERN Accelerator School (CAS), and we've successfully organised over a hundred accelerator schools worldwide. In addition, we have compiled more than fifty reports, contributing to advancements in accelerator science.

To mark this anniversary, we cordially invite you to the CAS40 concert on 14 September at 12.30 p.m. on the lawn in front of Restaurant 1. Come with your colleagues and friends to unwind, relish some delightful drinks and enjoy live music during your lunch break. A group photo capturing this joyous celebration will be taken using a drone, with the participants spelling out CAS40, and we would like you to be part of it!

In addition, that same week, you'll find a selfie machine set up at Restaurant 1. We invite the entire CERN community to seize this opportunity to take a selfie and share it on social media using @CERN and #CAS40 to spread awareness about the significance of education and scientific knowledge dissemination in driving technological progress.

Let’s make this celebration unforgettable. See you there!
