Cryogenic and thermal system component technologies are grouped in the following categories: micro-Kelvin, sub-Kelvin (K), 4 to 20 K, and low-cost cryocoolers; all have requirements for low power, low mass, and low exported vibration during operation.","exampleTechnologies":"Adiabatic demagnetization refrigerators; dilution refrigerators; sorption coolers and supporting components; cryocoolers, like Stirling refrigerators, Brayton Cycle refrigerators, pulse tube refrigerators, Joule-Thomson coolers; and supporting cryogenic thermal control components like heat straps, heat pipes, cryogenic radiators","hasChildren":false,"hasInteriorContent":true}],"startTrl":4,"currentTrl":6,"endTrl":6,"benefits":"This proposal is geared towards development of light-weight low-current shielded low AC loss ADR and AMRR superconducting magnets that operate at above15 K, which NASA is currently calling for. Such magnets are key components for cooling of next generation telescopes and space astronomy missions.
Other than ADR and AMRR systems for NASA, applications of superconducting magnets operating at above 15 K include efficient motors and generators, MHD propulsion, high precision sensors and actuators, electromagnetic launch, and magnetic resonance imaging (MRI) both in space and earthbound suites.","description":"This proposal responds to the technological challenge of design and manufacture of shielded superconducting magnets generating 3-4 T at temperatures > 15 K. An efficient ADR or AMRR system is likely to be a multistage stage system having magnets operating at different temperatures. Known superconductors that can operate at > 15 K are: 1) YBCO tapes, 2) Bi2223 wires, 3) Bi2212 wires, 4) MgB2 wires, and 5) Nb3Sn wires. Our Phase I project will have the following technical objectives: a) development and testing of high current density low loss Nb3Sn wires, b) study of AC losses of shielded HTS ADR magnets, and c) development of magnet subcomponents with low eddy current losses. We expect our work on high critical current density low AC loss Nb3Sn wires to come to a successful fruition in the Phase I, and expect our Phase II R&D to be entirely dedicated to development of shielded HTS and MgB2 magnets.","startYear":2016,"startMonth":6,"endYear":2016,"endMonth":12,"statusDescription":"Completed","principalInvestigators":[{"contactId":431385,"canUserEdit":false,"firstName":"Shahin","lastName":"Pourrahimi","fullName":"Shahin Pourrahimi","fullNameInverted":"Pourrahimi, Shahin","primaryEmail":"Pourrahimi@Ssi99.Com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":132441,"canUserEdit":false,"firstName":"Edgar","lastName":"Canavan","fullName":"Edgar R Canavan","fullNameInverted":"Canavan, Edgar R","middleInitial":"R","primaryEmail":"ed.canavan@gsfc.nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[{"file":{"fileExtension":"pdf","fileId":302706,"fileName":"SBIR_2016_1_BC_S1.09-7386","fileSize":134615,"objectId":299251,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"131.5 KB"},"files":[{"fileExtension":"pdf","fileId":302706,"fileName":"SBIR_2016_1_BC_S1.09-7386","fileSize":134615,"objectId":299251,"objectType":{"lkuCodeId":889,"code":"LIBRARY_ITEMS","description":"Library Items","lkuCodeTypeId":182,"lkuCodeType":{"codeType":"OBJECT_TYPE","description":"Object Type"}},"objectTypeId":889,"fileSizeString":"131.5 KB"}],"id":299251,"title":"Briefing Chart","description":"Low Loss Superconducting Magnets Operating at 15 -

The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
