Facility access panels
07 May 2009



ISIS operates nine Facility Access Panels (FAPs) to peer review all beamtime proposals.

​FAP members reviewing proposals.


Panels meet twice a year, in June and December. Proposals are ranked on a scale from 10 (world class) to 1(unsatisfactory).

The work of pane​l members is covered by the Seven Principles of Public Life set out by the UK government.  Full guidance on FAP processes can be found in the Panel Guidelines​ document given to all panel members for each meeting.

In particular, panel members must declare all conflicts of interest and are expected to leave the room during discussion of proposals from their own departments or proposals with which they are associated.

FAP panel member selection

FAP members are selected from academia and industry. Up to two ISIS representatives act as secretaries and give technical advice. 

Anyone willing to become a FAP member is now asked to complete a short online form.  This will create a pool of possible members, and a small panel will select those needed for FAP meetings over the coming year.  A document describing the new process more fully can be found here​.

​ISIS Facility Access Panel Pool - new member form

ISIS Facility Access Panels

FAP1 Crystallography:  deals with structural studies across a broad range of physical science areas

FAP2 Disordered materials:  structural studies on liquids and disordered materials, again across a broad range of science areas

(FAP3 has now been split into FAPs 8 and 9).

FAP4 Excitations:  magnetism and superconductivity primarily, along with functional materials, focusing on the magnetic, electronic or structural excitations

FAP5 Molecular spectroscopy:  spectroscopy in chemical, materials science and bio-science systems primarily, including catalysis

FAP6 Muons:  muon studies across a broad range of physical and chemical science areas

FAP7 Engineering:  engineering studies, mainly stress/strain and texture mapping in engineering components. Also assessment of  archaeological proposals.

FAP8 Small Angle Scattering:  probing length scales from the nm to the um, with applications in studies of polymers, biological molecules, nanoparticles, microemulsions and liposomes

FAP9 Reflectometry:  structures of thin films, from mater​ials science through to soft matter and bioscience.

FAP10 Chip Irradiation:  rapid testing of high energy neutron effects in microelectronics

STFC nominations for committees, boards and panels

There are periodic calls for STFC boards and advisory bodies.​
