Description
The recent rise of fast timing applications at high radiation fluences requires testing in low-temperature environments (< -40°C) to mitigate thermal runaway for multi-pixelated matrices bonded to readout ASICs and to regulate carrier mobility. To that end, we present an upgraded infrastructure for the EUDAQ-based AIDA telescope at the SPS North Area H6B beamline. The system integrates a 1.2 kW water-cooled, ethanol-based chiller, a low-mass, 0.035 W/mK thermal conductivity wall, cold box and a two-axis (Y-Z) mechanical stage with a 34.2 kN dynamic carrying load, 5 mm pitch, and 1 m travel range. The cold box, with internal usable dimensions of 37 × 30 × 31 cm, supports a removable DUT assembly designed for 30 nm positioning precision and plane-independent 3-axis movement (2 linear and 1 rotational). In addition, accompanying control hardware and software are under development to enable temperature and flow control, seamlessly integrating as a EUDAQ-level producer. To address the 130 nsec trigger decision latency of the AIDA TLU 2, we introduce a fast trigger decision board. The latter, targeting latencies below 10 nsec, while incorporating a synchronization subsystem with the accelerator clock, represents a critical improvement for timing applications.
