Accessing the XRD SRF

To arrange access to the world class facilities available in the X-ray Diffraction SRF, please follow these instructions:

 

For staff & students of the Department of Materials Science & Engineering

 

Contact the XRD SRF manager by email at n.reeves@sheffield.ac.uk, stating the following information:

 

1.  Your full name

2.  Your supervisor(s) name(s), indicating who is 'most' responsible for your funding

3.  What elements are present in your sample(s)

4.  Whether your samples are solid or powdered materials

5.  How much you will typically have of each sample

 

 

For other staff of the University of Sheffield

 

We warmly encourage people from all over the University of Sheffield campus to make use of our facilities.  If you wish to arrange access for yourself or your research staff/students, please contact the XRD SRF manager by email at n.reeves@sheffield.ac.uk to discuss which instrument would be most suitable for your samples and access fees (which also includes full training in operation of the instrument and basic data analyses).  Access fees are billed quarterly and dependent on the number of sessions used.

 

 

Training

 

I offer training sessions at specific times on Thursday afternoons.  Users should pre-book in with me, either in person or by email, for training sessions as follows:

     13:00               Cu-STOE PSD

     13:30               Cu-STOE IP-PSD

     14:00               Siemens D500

     14:30               PW1830

     15:00               Siemens D5000 (Co)

     15:30               Phase Analysis

     16:00               MoSTOE PSD

Once training has been satisfactorily trained, approved users may use the online booking system below to reserve sessions on instruments up to 10 days in advance.

 

 

For external users

 

The XRD SRF also offers a high-level bespoke service for other institutions and industry partners, offering the following services:

 

  • Qualitative phase analysis - "What is it?"
  • Quantitative phase analysis using the Rietveld method
  • Retained Austenite calculation by XRD using methods based on ASTM Standard Practice E975-84
  • Crystallite size determination by XRD
  • Residual strain analysis on small specimens
  • Lattice parameter determination and solid solution studies
  • Crystal structure solution using the Rietveld method

 

To discuss your XRD needs and request a quote for work, please contact Dr Nik Reeves-McLaren by email at n.reeves@sheffield.ac.uk.  We try, where possible, to complete all works within 2 weeks of receipt of samples.

Safety!

Notes for X-Ray Users

 

The "local rules" governing the XRD lab can be found on the Safety Services website.  The XRD Lab is classified as a "Supervised Area".


1. Guidance for users of x-ray crystallographic equipment

2. Aspects of regulatory guidance applicable to work with x-rays

3. Generic prior authorisation for x-ray work under IRR99

From Safety Services

 

Note:

It is a legal requirement that all users of the XRD SRF attend an X-ray Safety training course once every three years.

 

If you have not attended one within the last three years (or ever), please watch this space for info about the next course!

 

A more specific comment on the (very low!) radiation levels within the SRF can also be found here.
