Design of a Silicon Beam for Detecting Deflagration of Trace Explosive

Deflagration experiments of trace explosive were presented; a kind of sensitive silicon beam for detecting radiation in the deflagration of trace explosive was designed. The silicon beam had a heating and a thermal resistors on it, used as stimulating and detecting elements respectively. thermal-electric simulation of the silicon beam was carried out by finite element analysis software ANSYS, and some silicon beams of this kind have already been fabricating now. These works provide basis for developing a new device for detecting trace explosive.
