A highly granular silicon-tungsten electromagnetic calorimeter (SiW-ECAL) is the reference design for the ECAL of the ILD concept, one concept for detectors at the future International Linear Collider. Prototypes for a SiW ECAL are developed within the CALICE Collaboration.

A highly compact digital readout card (SL-Board), is now available. The SL-Board combines data acquisition, power regulation and signal buffering for up to 10000 readout channels on a surface as small as 18×4cm^2. The system complies with space constraints in modern particle physics detectors such as ILD. The SL-Board can be read out by a regular USB interface or via a dedicated module (CORE Module). The CORE Module also delivers clock and fast commands and synchronises the SL-Boards. It acts as a data concentrator receiving input from up to 15 layers. The entire system is designed for a data throughput of up to 80 MBit/s.

In the next beam test in May 2021, we will read out up to 22 layers with the new system.

TIPP2020 abstract resubmission? Yes, this would have been presented at TIPP2020.
