Description

The European Spallation Source (ESS) will be multi-disciplinary research centre based on the world’s most powerful neutron source. This new facility will be around 30 times brighter than today's leading facilities, enabling new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics. We summarise the key technical challenges facing us at the ESS focusing in particular on data collection and instrument timing.

Summary

The European Spallation Source (ESS) in Lund, Sweden is in the
construction phase with the first three neutron instruments
moving into detailed design in 2015. This new generation of
pulsed source requires a new complexity and flexibility of
instrumentation to fully exploit its opportunities. We present
details of the data acquisition strategy for instrument readout,
where 'event mode' data packets capture each neutron
candidate independently. Neutron data and metadata are
timestamped, and only by comparing neutron timestamps with beam
forming 'chopper' timings, and/or sample environment
timing, can science data be extracted. An instrument
can be well over 100m long; this requires accurate timing
across the various data collection points.
A distributed solution is being implemented. We present
details of the local timing and data collection systems
which interface to the wider control system and
remote data centre.
