Design of a Flexible PCB prototype for the High Granularity Timing Detector at ATLAS — •Maria Soledad Robles Manzano^1,2, Peter Bernhard², Andrea Brogna², Atila Kurt², Lucia Masetti^1,2, Paul Plattner¹, and Quirin Weitzel² — ¹Institut für Physik, Johannes-Gütenberg Universität Mainz — ²Exzellenzcluster PRISMA, Johannes-Gütenberg Universität Mainz

The High-Granularity Timing Detector (HGTD) is designed to improve the physics performance in the forward region of the ATLAS detector when the new HL-LHC is operative. Based on Low Gain Avalanch Detectors, the HGTD will mitigate the pile-up in the forward region by providing a timing resolution below 30 ps per track. In this scenario, the HGTD requirements for data transmission (1.28 Gb/s), sensor powering (up to 1 kV) as well as the geometrical constraints (thickness below 350 µm) lead to the need of custom designed electronics. A Flexible PCB (FLEX cable) is the best candidate to fulfil both the electrical and geometrical requirements. The design of the first prototype is presented.
