  The Multi-Blade (MB) Boron-10-based neutron detector is the chosen technology
for three instruments at the European Spallation Source (ESS): the two ESS
reflectometers, ESTIA and FREIA, and the Test Beam Line. A fourth MB detector
has been built, installed and commissioned for the user operation of the
reflectometer Amor at PSI (Switzerland). Amor can be considered a downscaled
version of the ESS reflectometer ESTIA. They are based on the same Selene guide
concept, optimized for performing focusing reflectometry on small samples. The
experience gained at Amor is invaluable for the future deployment of the MB
detector at the ESS. This manuscript describes the MB detector construction and
installation at Amor along with the readout electronics chain based on the
VMM3a ASIC. The readout chain deployed at Amor is equivalent of that of the
ESS, including the readout master module (RMM), event-formation-units (EFUs),
Kafka, FileWriter and live visualisation tools.
