The primary objective of this research program is to play a leading role in, and provide a Canadian contribution to, the advancement of the Far-Infrared (FIR) instrumentation needed for near-term and long-term future FIR astrophysics space missions. This involves direct participation in the development of the Canadian contribution to two FIR decadal roadmap pillars: 1) cooled aperture instrumentation, and 2) interferometry. Canada has established itself as the go-to partner for low power cryogenic mechanisms and metrology, resultant from current technology developpment in cryogenic FTS technology. NASA's annual technology gap assessment currently places Canada as the leading player in cryogenic FTS, giving Canada the pole position for the next generation far-infrared space missions, which will feature FTS instrumentation. This research vision also involves exploration and advancement of spectroscopic and interferometric techniques in support of a long-term FIR spatial/spectral interferometry space mission. Finally, this involves the development and mechanical/thermal/optical/spectral characterization of space-qualified cryogenic materials and components including carbon-fibre composite materials. This research program will make contributions to many aspects along the FIR roadmap including the exploitation of current results and facilities and collaboration with future experiments, facilities, and observatories. This research will provide HQP training to many students through a combination of hands-on instrumentation development and the broad perspective provided by participation in large international collaborations. The resultant technological advances will allow astronomical observations to be undertaken in shorter observation times, over larger regions of spatial coverage, or of greater spatial resolution; all with increased sensitivity over the current state of the art. Current work in this field is at very early stages on the global field. This research program provides a ground floor opportunity to become a key partner in future-generation ground and space based FIR astronomy observatories, providing excellent opportunities to train students and researchers. While this work is in many aspects unique within Canada, and the world, it complements the existing research network both locally and internationally, and will fortify existing and anticipated international collaborations into the future.

该研究方案的主要目标是在推动远红外天体物理学空间飞行任务近期和长期所需的远红外仪器方面发挥主导作用并作出加拿大的贡献。这包括直接参与制定加拿大对飞行情报区十年路线图两个支柱的贡献：1）冷却孔径仪器，2）干涉测量。加拿大已成为低功率低温机制和计量学的首选合作伙伴，这是低温FTS技术当前技术发展的结果。美国宇航局的年度技术差距评估目前将加拿大列为低温FTS的主要参与者，使加拿大在下一代远红外空间任务中处于领先地位，该任务将采用FTS仪器。这一研究设想还涉及探索和发展光谱和干涉测量技术，以支持长期的远红外空间/光谱干涉测量空间使命。最后，这涉及开发符合空间要求的低温材料和部件，包括碳纤维复合材料，并确定其机械/热/光学/光谱特性。该研究计划将为沿着FIR路线图的许多方面做出贡献，包括利用当前的结果和设施以及与未来实验，设施和观测站的合作。这项研究将提供HQP培训，许多学生通过动手仪器的开发和参与大型国际合作提供的广阔前景相结合。由此产生的技术进步将使天文观测能够在更短的观测时间内、在更大的空间覆盖区域内或以更高的空间分辨率进行;所有这些都比目前的技术水平具有更高的灵敏度。该研究计划提供了一个底层的机会，成为未来一代地面和空间基于FIR天文观测站的关键合作伙伴，为培训学生和研究人员提供了极好的机会。虽然这项工作在加拿大和世界上的许多方面都是独一无二的，但它补充了当地和国际上现有的研究网络，并将加强现有和预期的国际合作。
