Structural Biology Proposals

Structural Biology Beamline - Introduction

The facilities for Structural Biology comprise 8 dedicated end-stations (ID23-1, ID23-2, ID29, BM29, ID30A-1, ID30A-3, ID30B, CM01) and the CRG beamlines BM07 and CM02 that make 33% of their beamtime available for peer-reviewed public access. These 10 end-stations provide facilities for Macromolecular Crystallography (MX), Serial Synchrotron Crystallography (SSX and TR-SSX), BioSAXS and Cryo Electron Microscopy (CryoEM) on biological samples.

There are currently two access modes for public Structural Biology beam-time:

• Block Allocation Group (BAG) Proposal: Large, well-established groups requiring a significant amount of beam-time should apply for BAG status
• Rolling Access Proposal: For groups requiring beam-time for a single or small number of projects.

ILL/ESRF Joint SANS-SAXS Proposal

To improve access to the complementary techniques of SAXS and SANS, users submitting a SANS proposal to the ILL have the option on the ILL proposal form to ask for complementary SAXS measurements on beamline BM29 through the PSB SANS-SAXS Platform. If the proposal is awarded beamtime at the ILL, the proposers are invited to contact mx-scheduling to arrange for ESRF beamtime to be scheduled under the SANS-SAXS BAG proposal number. Every effort will be made to schedule the experiments in such a way that SAXS and SANS data can be collected on the same samples during one visit to the EPN Campus site.
