Abstract
Abstract
The University of Bergen is involved in developing two calorimeters: the pixel section of
the Electromagnetic Forward Calorimeter for the ALICE Upgrade to be installed during LS3 for
data-taking in the period 2029–2032 and the Digital Tracking Calorimeter for the proton Computed
Tomography prototype. Both designs utilize pixel sensors and require a reliable connection to the
readout which is positioned approximately 5 meters away. Furthermore, the structural design of
these calorimeters calls for a compact layer assembly. This paper provides the strategies
deployed to meet these critical requirements, focusing on the implementation of the chip-on-flex
assembly, and the ultrasonic welding techniques. It further describes other design considerations
essential for maintaining good signal integrity. Finally, it gives insight into the experiences
and challenges faced while working with the prototypes, both in the laboratory and test beam
setups.
