UK Catalysis Hub


Diamond Light source B18 BAG

Block Allocation Group (BAG) Programme Mode Application to Diamond Light Source:


The proposal is made on behalf of the UK Catalysis Hub network and intends to provide members with frequent and flexible access to B18, the core XAFS beamline. We have actively embraced new users and new areas of catalysis, assigning time across a broad range of catalytic science (homogenous catalysis, heterogeneous catalysis, biocatalysis, and electrocatalysis). To date we have supported the research efforts of > 20 research teams from > 10 institutions.

Project Prioritisation 

 The BAG allocation prioritieses access based on

 (i) the quality of the underpinning science, 

(ii) the likely success of the experiments, 

(iii) bringing in new users of synchrotron radiation, and

 (iv) coordinating time effectively to maximise efficiency.

  This level of access improves the efficiency of data acquisition by the coordination of projects to reduce the dead time of experimental set-up and by allocating small amounts of time for proof of concept investigations before a full study is commenced. 

The BAG allocation time is assigned by an executive panel comprising of:

  •  representation from Diamond;
  •  Prof. Richard Catlow;
  •  Dr. Peter Wells; 
  •  representation from two other institutions (changed on a rolling basis). 

It is important to note that that for heavy users of synchrotron facilities this method of access will only play a small contribution to the amount of time they require. Their role within the BAG proposal is to provide the interface between the inexperienced members and Diamond, enabling a larger cross section of the UK Catalysis Hub network to benefit from the techniques available. These users may receive small amounts of flexible access, where required, to assist in finishing research projects and hasten subsequent publications.


BAG so far 

As of October 2015 a total of 39 days (excluding reassigned days) have been received. In the 36 months since the 1st beamtime, this has resulted in 16 published articles, with more currently under review. The accepted articles have included publications in high impact journals including JACS, Chemistry of Materials, ACS Catalysis and Chemical Science.
