GGG crystal wafers and Substrates

● Fine mechanical, optical and chemical properties
● Excellent as optical, microwave isolator and HTS substrates

GGG crystal wafers is material with good optical, mechanical and thermal properties which make it promising for use in fabrication of various optical components as well as substrate material for magneto – optical films and high – temperature superconductors. It can be used for infrared optical isolator (1.3 and 1.5 um), which is made of YIG or BIG film on the Gadolinium Gallium Garnet (GGG) substrate plus birefringence parts. GGG crystal wafers is an important substrate for microwave isolators and can be used as a HTS material, for laser technology, telecommunications, electronic.

A Small-Animal PET System Based on LYSO Crystal Arrays

A positron emission tomography system for small animals has been designed for research purposes. Its detection modules are based on pixelated scintillator LYSO crystal arrays coupled to Hamamatsu H8500 position-sensitive photomultiplier tubes. The front-end electronics are based on nuclear instrumentation modules (NIM) and in-house built readout circuits. Peak signal digitization is performed with a commercial analogue-to-digital acquisition (DAQ) board.

The system has been characterized for spatial, timing and energy resolution, system dead time, absolute sensitivity, scatter fraction and noise equivalent count rate (NEC).

The results indicate that the detection modules are able to identify individual crystals (out of 400) with up to 8-to-1 peak-to-valley ratios with individual crystal energy resolution ranging from 7 to 15% at 511 keV. The timing resolution is 1.9 ns and the system dead time was found to be 16.8 ¿s and 42.1 ¿s for 0.5 ml and 10 ml volume sources, respectively. The measured absolute system sensitivity is 0.11% and the scatter fraction from a glass capillary inside a 2.5 cm diameter mouse phantom is 21.5%. A true NEC maximum value was not achieved with the system due to saturation of the PS-PMT output signals for activities above 0.27 mCi. Results from a Na18 F PET bone scan of a 30 g mouse are shown.
