The Diamond Light Source invites proposals for its rapid access to selected beamlines and electron microscope. This provides candidates with quick and urgent access to one of the following beamlines: electron microscope, MX beamlines, 106, 108, I11, I13-1, I13-2, B16, B18, I18, I19, B21, B22 and B23.

Applicants from any sector may apply; however, postdoctoral applicants, support scientists, postgraduate and undergraduate students may not act as principal investigators. Users are advised to contact the principal beamline scientist prior to application as some beamlines have restricted amount of rapid access available.

In steady state 80 per cent of beamtime is available to external users and 20 per cent beamline for development and in-house research. Industrial users may have up to 10 per cent of the beamtime allocated to external users, with only 30 per cent available per beamtime.
