Abstract
As part of the AMBER (NA66) upgrade program, we have designed and built a resistive bulk
Micromegas (MM) detector with a total active area of 1.0 x 0.5 ๐‘š2 per module, intended to
replace selected Multi-Wire Proportional Chambers in the spectrometer. The detector comprises
three independent side-by-side modules; each module hosts two readout planes in a face-to-face
configuration sharing a central cathode, enabling XUV tracking. For the lateral modules, a uniform
Diamond-Like Carbon (DLC) resistive layer was adopted to mitigate discharge probability while
preserving efficiency at high gas gain. The first module-currently the largest operating resistive
bulk MM of its kind was completed in October 2024 and is under test. Meanwhile, considering the
need for new triggerless compatible readout electronics, we are developing a 64-channel mixed-
signal front-end ASIC(Torino Readout for AMBER - ToRA), optimized for time and energy
measurements. This article review detector design, production, first operation, and ongoing
development of the ToRA-based readout chain.
