High-end applications of barium fluoride

Barium fluoride crystal (BaF2) has good optical transmission properties and can be used as ultraviolet and infrared optical windows in the spectral range of 0.15μm-14.5μm. At the same time, it has excellent scintillation performance. Its role in the analysis of cadmium, antimony, and zinc is more obvious than that of indium bismuth and lead. It has become an important crystal material in the fields of high energy physics, nuclear physics, and nuclear medicine.

In high-energy physics experiments, the detection of photons occupies a very important position. The detection of photons is mainly realized by measuring the electromagnetic showers it produces in matter. With the continuous increase of the energy of high-energy accelerators, the photons studied The energy is also getting higher and higher, which requires the material used in the detector to have both high blocking ability, good time resolution, energy resolution and radiation resistance.
