The Electro-Thermal Characterization of a Multi-Moded Bolometer characterize the electrical and thermal performance of large multi-moded bolometers for a new generation of far-infrared instrumentation. Multi-moded systems provide distinct advantages compared to current single-moded designs. By collecting more photons on each detector, multi-moded designs improve sensitivity by an order of magnitude. One multi-moded detector can thus replace 100 single-moded detectors, providing two orders of magnitude reduction in detector count while simplifying instrument design, integration, and testing.
The project work will test a far-IR detector with 30 times the absorbing area as the bolometers flown on the Planck mission.

Additionally, we will extend the detector capabilities to include the much higher optical loads encountered during use in stratospheric balloon payloads.More »
By reducing the number of detectors required for photon-limited applications, the multi-moded bolometer can decrease the cost of detector and readout systems by a factor of ten or more.More »

This project modified previous the previous PIXIE multi-moded detector to accommodate the x10,000 higher absorbed power encountered during sub-orbital observations from a balloon platform.
The purpose of the Goddard Space Flight Center’s Internal Research and Development (IRAD) program is to support new technology development and to address scientific challenges. Each year, Principal Investigators (PIs) submit IRAD proposals and compete for funding for their development projects. Goddard’s IRAD program supports eight Lines of Business: Astrophysics; Communications and Navigation; Cross-Cutting Technology and Capabilities; Earth Science; Heliophysics; Planetary Science; Science Small Satellites Technology; and Suborbital Platforms and Range Services.
Task progress is evaluated twice a year at the Mid-term IRAD review and the end of the year. When the funding period has ended, the PIs compete again for IRAD funding or seek new sources of development and research funding, or agree to external partnerships and collaborations. In some cases, when the development work has reached the appropriate Technology Readiness Level (TRL) level, the product is integrated into an actual NASA mission or used to support other government agencies. The technology may also be licensed out to the industry.
The completion of a project does not necessarily indicate that the development work has stopped. The work could potentially continue in the future as a follow-on IRAD; or be used in collaboration or partnership with Academia, Industry, and other Government Agencies.
