Progress in the X-ray Optics and Metrology Lab at Diamond Light Source

Diamond Light Source, located in Oxfordshire, UK, is one of the world’s most advanced synchrotron radiation facilities. It produces brilliant X-rays that scientists from various fields use to study the structure and properties of materials at the atomic and molecular level. At the heart of this facility lies the X-ray Optics and Metrology Lab, a crucial component responsible for developing cutting-edge X-ray optics and instruments. In recent years, the lab has made significant progress, including advancements in the use of lab grown diamond as a key material for X-ray optics.

The X-ray Optics and Metrology Lab is a collaborative effort involving scientists, engineers, and researchers from diverse backgrounds. Their common goal is to push the boundaries of X-ray optics and enhance the capabilities of Diamond Light Source for scientific investigations. One of the significant challenges in X-ray optics is to focus and manipulate X-rays with high precision and efficiency. Lab-grown diamond has emerged as a promising material for achieving this goal.

Diamond is renowned for its exceptional properties, including its high refractive index, excellent thermal conductivity, and extreme hardness. These properties make it an ideal material for X-ray optics. In the X-ray Optics and Metrology Lab, researchers have been exploring the use of lab-grown diamond as diffractive optical elements, such as beam splitters and monochromators.

Lab-grown diamond diffractive optical elements offer several advantages over traditional materials. Their high refractive index allows for efficient focusing of X-rays, enabling enhanced spatial resolution in X-ray imaging. The exceptional thermal conductivity of diamond also ensures that the optical elements remain stable even under intense X-ray beams, reducing the risk of thermal distortion and damage.

One of the key achievements in the lab has been the development of novel X-ray focusing optics using lab-grown diamond. These optics, known as kinoform lenses, are based on the principle of diffractive focusing, which exploits the wave nature of X-rays. Kinoform lenses can focus X-rays to nanometer-sized spots, enabling scientists to study materials with unprecedented detail.

In addition to focusing optics, lab-grown diamond has also shown promise in the field of X-ray monochromators. Monochromators are essential components that select a specific X-ray wavelength from the synchrotron radiation spectrum, allowing researchers to perform precise X-ray spectroscopy and diffraction experiments. Diamond monochromators are highly desirable due to their high efficiency and stability.

Moreover, the X-ray Optics and Metrology Lab has been actively involved in characterizing the properties of lab-grown diamond to optimize its performance in X-ray optics. Researchers have studied the crystallographic structure, surface quality, and thermal properties of diamond samples to understand their behavior under X-ray irradiation. This knowledge is critical for tailoring diamond optics for specific X-ray beamlines and experimental requirements.

As the field of X-ray optics continues to evolve, the X-ray Optics and Metrology Lab at Diamond Light Source remains at the forefront of innovation. The progress made in utilizing lab-grown diamond in X-ray optics has opened up new possibilities for scientific research. The development of advanced X-ray focusing optics and monochromators has enabled scientists to investigate materials with unprecedented precision, leading to discoveries in various fields, from materials science to biology and beyond.

In conclusion, the X-ray Optics and Metrology Lab at Diamond Light Source is making significant strides in advancing X-ray optics using lab-grown diamond. The unique properties of diamond, such as its high refractive index and thermal conductivity, make it an ideal material for X-ray optics applications. The lab’s efforts in developing kinoform lenses and diamond monochromators have revolutionized X-ray experiments, enabling researchers to gain deeper insights into the atomic and molecular structures of materials. As this research continues, the potential for even greater discoveries using lab-grown diamond in X-ray optics is both exciting and promising for the scientific community.
