- Description
- NASA/MSFC has a requirement for a broad (approximately 9 cm in diameter) monoenergetic, monodirectional ion source that is capable of producing 1 eV to well above 30,000 eV ions with a current density ranging from approximately 1x10-14 Amps/cm2 to 1x10-8 Amps/cm2. Presently in the Low Energy Electron and Ion Facility (LEEIF), ions of energy 0.6 ? 2600 eV are produced in an electron bombardment ion source with an effective circular aperture of approximately 9.0 cm diameter. A tandem electrostatic and variable geometry magnetic mirror configuration within the ion source optimizes the use of the ionizing electrons, thus decreasing the gas and non-thermal electron throughput to the instrument chamber while improving the flux uniformity. Each controlled voltage decade has 12 bit resolution: 0-30V, 30V-300 V, 300 V-3000 V. The beam is imaged to the plane of the admittance aperture of the instrument. The usable current density is approximately 1pA/cm2 at beam energies as low as 1 eV, with higher values, up to 1x10-10 A/cm2 , available with increasing energy. The beam energy spread is typically less than 0.3 eV and the average angular divergence is approximately ?0.75?. Photographs, a few assembly drawings, and the electrical wiring schematics of the ion source assembly are available. We now have calibration requirements to expand the energy capability of the LEEIF ion source from 1eV to 40 keV energies. With that in mind, we are requesting a 1 eV to well above 30 keV ion source that is capable of providing final calibration level measurements for particle detectors before flight. This requires an ion source of a similar design ranging in voltages from less than 1 V to above 30 kV that is also spatially broad, mono-energetic, mono-directional, and with the required current density levels. Our objective is to provide one ion source that is of calibration level for flight instrumentation. The resulting ion source specifications are: 1. Energies ranging from below 1 eV to well above 30 keV, voltage allowance to accommodate energies of less than 1 eV to well above 30 keV. 2. An effective circular aperture of approximately 9 cm in diameter or greater 3. Well-collimated and a spatially broad beam from point of extraction to instrument aperture, present ion source diameter stated above. 4. Monoenergetic (i.e. small temperature spread), monodirectional (i.e. small trajectory angles) 5. Appropriate flux levels for instruments for lunar, heliospheric and geospace missions. Current densities ranging from 1x10-14 Amps/cm2 to 1x10-8 Amps/cm2 6. Connection allowance for each voltage or current controlled element in the ion source and for feedback control of absolute beam current 7. Ion source elements similar to our present design including a variable magnetic mirror configuration 8. Allowance for large power capability to filament NASA/MSFC intends to purchase the items from Colorado State University because they have (A) extensive knowledge of different type of ion sources including low temperature sources and high-energy particle sources. They have (B) extensive experience in solutions for sputtering and arcing problems that are inherent to the high voltage side of this source. The lead time for this requirement is 6-months. The Government does not intend to acquire a commercial item using FAR Part 12. See Note 26. Interested organizations may submit their capabilities and qualifications to perform the effort via email at iris.r.walter@nasa.gov or via fax at 256-961-7723 to Iris Walter, Digital Fusion Solutions, Inc., PS51 not later than 4:30 p.m. local time on Friday, August 3, 2007. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the government. Oral communications are not acceptable in response to this notice. All responsible sources may submit an offer which shall be considered by the agency. An Ombudsman has been appointed.
