I15 and I15-1 are dedicated high energy beamlines, enabling diffraction and scattering experiments. Their unique capabilities make them perfect for dense or complex sample assemblies, permitting detailed mapping of structural order or disorder, chemical fingerprinting or structure determination.
Unlike other research instruments, I15 can provide a continuum of energies, whilst I15-1 provides three energies up to 76kV. These high energies make them perfect for studying catalytic mechanisms, investigating adsorption in porous materials, or characterising the structural rearrangements that accompany electron flow in battery materials.
I15 can focus with detailed precision (down to 10 µm) on a specific area of interest, and both provide the flexibility to tailor experiments to your exact needs. This includes in situ investigations and studies under extreme conditions (pressure and temperature).
I15 actually consists of two separate beamlines which run independently of one another, I15 and I15-1. They both provide unique capabilities:
With I15, users are able to focus in on very fine detail (down to 10 µm) and explore a sample with high spatial resolution. This beamline uses a double crystal monochromator that allows it to work within a wide range of energies (20-80 keV). It also has a micromanipulator ‘Axis Pro’ for quick and effective loading of a diamond anvil cell.
I15-1 uses three different crystals to choose the energy of the beam. It is fixed, providing the opportunity for experiments using a wide range of different experimental environments. This beamline is perfect for investigations of X-ray Pair Distribution function, enabling the local structure of samples, with high X-ray energy, high flux and low background signal for high quality data.
Between them, I15 and I15-1 provide a wide range of unique capabilities. With their ability to produce high energy X-rays and precision focus (down to 10 μm), these beamlines are able to penetrate and map dense or complex samples which would otherwise prove extremely challenging.
Both beamlines provide the flexibility to tailor experiments to operate within different environments (such as extreme pressure and temperature). This enables users to replicate real life conditions and to conduct investigations in situ, to capture changes as they happen.
I15 and I15-1 maximise the benefits of Powder Diffraction and X-ray Pair Distribution Function, to understanding the local atomic structure and the chemical and physical interactions that occur on the atomic scale – this may involve catalytic mechanisms, investigating adsorption in porous materials, or characterising the structural rearrangements that accompany electron flow in battery materials.
The beauty of using these beamlines at Diamond is that they offer a lower barrier to entry, so you can conduct your experiment without the cost of an in-house solution. You’ll also benefit from the expertise of the Diamond staff who can support you throughout your experiment and help you get the maximum benefit from your time at Diamond.
Each of the beamlines also hold their own unique benefits:

I15/I15-1 beamlines can be used across a wide range of research topics including fundamental Physics and Chemistry, Earth and Planetary Science as well as Material Science and Engineering. Below are some of the applications:
Earth sciences – oil, gas, coal
Material science
Synthesis
Batteries
MOFs (metal organic frameworks)
Pharmaceuticals
Energy
During 2020/1, both I15 and I15-1 will be fitted with new CdTe based detectors. These will provide enhanced signal to noise conditions resulting in improved data collections.
I15 beamline will undergo an upgrade during this period. This will include increased motor speed and spatial scanning capabilities, to make data processing much faster.
The implementation of 2D maps with rotation will enable users to probe crystal entities, enabling them to determine individual grains within crystal samples. This will provide a better understanding of new materials formed at high temperatures and pressures.
The ability to study single crystals at higher energies will allow our users to gain a greater understanding of the atomic structure of their materials and extract more detailed information from the data acquired at the beamline.
We also plan to introduce a robotic sample handler into I15-1 beamline to automate sample transfer, enabling greater flexibility and efficiency as well as higher throughput.
