BaF2 Scintillator, BaF2 crystal, BaF2 scintillation crystal

short description:

BaF2 scintillator has excellent scintillation properties and optical transmission over wide spectrum range. It’s regarded as the fastest scintillators so far. The fast component can be used to measure time precisely and obtain good time resolution, it has been pursued as a promising scintillator in the research of positron annihilation. It shows excellent radiation hardness up to 10⁶ rad or even more. BaF2 crystals have excellent scintillation properties due to their ability to simultaneously emit fast and slow light components, enabling simultaneous measurement of energy and time spectra with high energy and time resolution. Therefore, BaF2 has a wide range of applications in the fields of high energy physics, nuclear physics and nuclear medicine.

Product Description

BaF2 stands for barium fluoride. It is a compound composed of barium and fluorine atoms. BaF2 is a crystalline solid with a cubic structure and is transparent to infrared radiation. Due to its good transmission properties over a wide wavelength range, it is often used as a material for lenses, windows and prisms in the field of optics. It is also used in scintillation detectors, thermoluminescent dosimeters, and other applications requiring radiation detection. BaF2 has a high melting point and is insoluble in water, making it a useful material in high temperature and corrosive environments.

Performance Testing

Energy spectra of the 2 × 2 × 3 mm3 BaF2 crystals measured on the (a) HF setup and (b) ASIC setup at a bias voltage of 60 V, with a threshold of 100-mV for the HF measurement and 6.6 mV for the ASIC setup. The HF spectrum is a coincidence spectrum, while the ASIC shows a spectrum of only one detector.
