I15-1 General Information

Here you will find some general information about the I15-1 beamline at Diamond Light Source.

Beamline Overview

The beamline is a high-energy scattering beamline designed specifically for performing total scattering and pair distribution function studies.

Energies / Wavelengths

I15-1 operates using a single-bounce monochromator, so we’re restricted to three pre-defined energies:

Energy / keV	Wavelength / Å	Potential Q_max / Å^-1

Energy / keV	Wavelength / Å	Potential Q_max / Å^-1
40.0	0.31	21
65.4	0.19	35
76.7	0.16	40

Detectors

I15-1 uses two Perkin Elmer detectors:

Det 1 (Bragg): Perkin Elmer XRD 1611 CP3; 4096 x 4096 pixels; 100 µm pixel size
Det 2 (PDF): Perkin Elmer XRD 4343 CT; 2880 x 2880 pixels; 150 µm pixel size

Collection Times

Whilst the amount of time required for a data collection depends on many factors, we typically estimate that a good quality PDF data set can be collected 3 to 4 times per hour.

Sample Environments

The beamline is equipped with a wide range of sample environments.

Capillaries

We strongly encourage all users to use the capillaries supplied by the beamline. For the full list of available capillaries, please see this page.
