Speaker
Description
AMBER is a new experiment at the CERN SPS dedicated to addressing fundamental questions in hadron physics using high-energy muon, pion, kaon, and proton beams. Following successful physics runs in 2023 and 2024, the experiment provided valuable input for dark matter searches through measurements of antiproton production cross sections on helium targets.
For the 2026 measurement of the proton electric form factor via elastic muon–proton scattering, several detector systems were upgraded to operate in a streaming readout mode. In particular, new large-area planar GEM detectors play a crucial role in tracking particles scattered at small angles, such as muons in elastic scattering events on hydrogen targets.
The transition from a triggered to a streaming data acquisition architecture required a complete redesign of the front-end electronics. The planar GEM tracking system for AMBER now employs a custom FPGA-based readout board in combination with the SRS VMM hybrid. Particular emphasis was placed on achieving the required streaming capabilities without compromising detector performance.
This presentation will provide an overview of the planar GEM-based tracking detectors, their readout architecture, and results from recent physics runs at the AMBER experiment.
