This Small Business Innovation Research Phase I project aimes to design and build a digitally-controlled vapor generator that will enable field calibration of vapor trace detectors for explosives. The technology risk-elements concern precisely delivering, under digital control, a dilute explosive mixture to a heated surface, converting it to a vapor and then delivering the vapor plume to a trace explosive detector to be tested or calibrated. Other technology issues relate to vapor generator precision, repeatability, and instrument reliability. Engineering issues concern the design and fabrication of a handheld prototype based upon a disposable cartridge approach. The handheld vaporjet calibration instrument will include standard test protocols with a user-friendly computer interface. It is anticipated that, during Phase I, the handheld unit will be tested and characterized with existing trace detector systems. There are tens of thousands of vapor trace detector systems deployed in the field today. They are operated by military personnel in Iraq, Afghanistan, and elsewhere; they are operated by government agents in airports, sub-way system, ports, embassies, consulates and public facilities across the globe; they are operated by private industry to protect their customers, employees and facilities. All these systems must be calibrated and verified on a regular basis. This need requires standard testing protocols for trace and stand-off detection methods and vapor sampling calibration methods. Sales will come from the calibration of detectors in the field, on manufacturing lines, and sales to R&D institutions for sensor development. Ultimately, real-time vaporjet calibration units could be designed into next generation sensor systems to insure consistent accuracy. Societal benefits include improved trace detection of explosives and other chemical threats.

这个小型企业创新研究第一阶段项目旨在设计和建造一个数字控制的蒸汽发生器，该蒸汽发生器将能够现场校准爆炸物的蒸汽痕量探测器。 技术风险要素涉及在数字控制下将稀释的爆炸性混合物精确地输送到加热表面，将其转化为蒸汽，然后将蒸汽羽流输送到痕量爆炸物探测器进行测试或校准。其他技术问题涉及蒸汽发生器的精度、可重复性和仪器可靠性。 工程问题涉及基于一次性盒方法的手持式原型的设计和制造。手持式蒸汽喷射校准仪器将包括标准测试协议和用户友好的计算机界面。预计在第一阶段，将用现有的痕量探测器系统对手持装置进行测试和表征。目前，在现场部署了数万个蒸汽痕量检测器系统。它们由伊拉克、阿富汗和其他地方的军事人员操作;它们由政府代理人在机场、地铁系统、港口、大使馆、领事馆和地球仪的公共设施操作;它们由私营企业操作，以保护其客户、雇员和设施。所有这些系统都必须定期进行校准和验证。这种需求需要标准的测试协议的痕迹和standoff检测方法和蒸汽采样校准方法。 销售额将来自现场、生产线上的检测器校准，以及销售给研发机构用于传感器开发。最终，实时vaporjet校准单元可以设计成下一代传感器系统，以确保一致的精度。社会效益包括改进对爆炸物和其他化学威胁的痕量探测。
