| Summary: | The MALTA silicon pixel detector combines a depleted monolithic active pixel sensor (DMAPS) with a fully
asynchronous front-end and readout. It features a high granularity pixel matrix with a 36.4 μm symmetric pixel
pitch, low power consumption of <1 μW∕pixel and low material budget with detector thicknesses as little as
50 μm. It achieves a radiation hardness to 100MRad TID and more than 1 × 10E15 1 MeV 𝑛eq∕cm2 with a time
resolution of <2 ns (Pernegger et al., 2023).<br>
In order to cover large sensitive areas efficiently with a minimum of power and data connections the
development of modules, comprising of up to 4 MALTA detectors, is studied.<br>
This contribution presents the beam test performance of parallel and serial powered MALTA 4-chip modules
in an effort to characterize the sensor’s chip-to-chip data and power transmission and prepare the production
of a first prototype of an ultra-light weight 4-chip module on a flexible circuit with next generation MALTA2
sensors.
