Kacper Jama and his team are focusing on the development of prototypes for the electromagnetic calorimeter (ECAL) upgrade of the LHCb experiment. For this project, many parts have been made in different laboratories, and some of them have been made here at ldeaSquare, such as the Light Guide (LG).
The light guide holds a pivotal position within the prototype, serving the essential function of directing light emanating from the fibres inside the prototype towards the Photomultiplier Tubes (PMTs) for accurate measurement. In essence, it plays a key role in shaping the trajectory of light to ensure optimal data acquisition.
The structure of the light guide (the black part in the picture) was 3D-printed and the mirrors were laser-cut here at ldeaSquare. This dual approach to manufacturing, combining the versatility of 3D printing with the precision of laser cutting, allows us to create these light guides in a very short time and with precise quality.
Ongoing projects within the laboratories involve the construction of various prototypes, each featuring distinct light guide configurations. This deliberate approach allows them to experiment with diverse setups and different PMTs, facilitating a comprehensive testing process that ensures the versatility and adaptability of our modules.
