The Osiris instrument is being upgraded with the addition of a silicon analyser, which will measure small energy transfers with high precision and provide new information about the mobility of ions, atoms and molecules on a longer timescale.

​The analyser team in front of the towers: 

Back row – Josef Lewis, Jim Baird, Luke Benson, Lucy Watts, Simon Canfer, Harry Plaisted, Nick Webb

Front row – Adi Bochare, Matt Croucher, Alex Penry, Joel Hodder, Ben Withers

 

Access to longer relaxation times will​ provide new opportunities to strengthen the science programme in ionic and proton conduction in complex media, or molecular transport in porous materials and catalysts of industrial relevance, which quite often suffer from present limits. 

The silicon analyser crystals have now been installed on the analyser towers, the collimator has been delivered, and the detectors are being assembled and tested.  This means that the full installation can start during this Winter shutdown, with commissioning expected in May/June 2026.
