Contacts
For corrections to the instrument tables, contact the Instrumentation team lead. For the software list and educational material, contact the Outreach team lead. For this website and the NCNR tools, contact William Ratcliff.
How to contribute
- Instrument data. Send corrections or a missing instrument to the Instrumentation team lead; the comparison tables are regenerated from one data file.
- Software. Send new packages, with a one-line description, language, platforms and a link, to the Outreach team lead.
- Teaching material and case studies. The Outreach team collects worked examples (linewidth studies, two-axis mode, thin films, MnF2 as a teaching experiment) for a future education page.
