mini-Gamma碘化晶體探測器采用4x4x8mm 碘化銫晶體配合PIN光電二極管構(gòu)建而成，與前置放大器封裝在金屬屏蔽盒內(nèi)，形成外形尺寸為18.2x12.2x6.4mm的探測器模塊，該模塊可以集成到智能手環(huán)、手表或手機中，形成具有檢測X射線功能的智能化數(shù)字產(chǎn)品。
mini-Gamma碘化銫晶體探測器由三個焊盤對外構(gòu)成電氣連接，分別是信號端，電源端及接地端，其中:
信號:半高斯成形脈沖信號，其幅度與入射到晶體上的X/V能量相關(guān)，在入射射線能量<1.2Mev的條件下，脈沖幅度與射線能量成線性關(guān)系。
電源:可采用2.0~5.5V電源，要求電源紋波盡量小，因為電源紋波會耦合到前置放大器中，產(chǎn)生額外的噪聲。
The mini-Gamma iodine crystal detector is constructed by combining a 4x4x8mm iodine cesium crystal with a PIN photodiode. It is encapsulated with a preamplifier in a metal shielding box, forming a detector module with an overall size of 18.2x12.2x6.4mm. This module can be integrated into smart wristbands, watches, or mobile phones to create intelligent digital products with X-ray detection capabilities.
The mini-Gamma cesium iodide crystal detector is electrically connected through three pads on the outside, namely the signal terminal, the power terminal and the ground terminal. Among them:
Signal: A semi-Gaussian shaped pulse signal, whose amplitude is related to the X/V energy incident on the crystal. Under the condition that the incident radiation energy is less than 1.2 MeV, the pulse amplitude has a linear relationship with the radiation energy.
Power Supply: A 2.0 - 5.5V power supply can be used. It is required that the power supply ripple be as small as possible, because the power supply ripple will couple to the preamplifier, generating additional noise.
