Near-field IR nanospectroscopy

The MIRIAM beamline B22 at Diamond Light Source offers near-field FTIR microscopy in photo-thermal mode (RE-AFMIR) for user research. This is a call for collaborative user proposals covering beamtime between 1^st April 2019 and 31^st September 2019.

Users
For this call we are offering the following experimental performances suitable for sub-micron feature to several micron sample scale:

• 100 nm scale resolution, sample thickness 100 nm up to few micron scale
• Continuous FTIR spectral coverage from 4000 cm^-1 to 800 cm^-1
• IR top illumination directly onto the sample or bottom illumination through a substrate
• nanoFTIR spectra acquisition between 1 to 10 min/point
• linescans 1D and maps 2D feasible (acquisition time to be scaled)

For these experiments it is essential that users have well-characterised samples, and have discussed the science and technical aspects with beamline staff prior to submission.

All proposals will be assessed and beamtime will be granted based on scientific merit with a strong emphasis on technical feasibility and sample/substrate suitability.

Interested users should submit application through the User Administration System (UAS) and choose the “commissioning” access route since this is a specific call for beamtime on a new MIRIAM/B22 end station.

The deadline for this call is 10^th December 2018

For technical questions about proposed experiments, please contact gianfelice.cinque@diamond.ac.uk, mark.frogley@diamond.ac.uk or ioannis.lekkas@diamond.ac.uk
