TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Combining Chemical Milling with wire Electrical Discharge Machining (EDM), Mindrum Precision will build a precollimator (PC) faster and more cost effective than current methods.

Space-based x-ray telescopes currently involve the use of a PC to shield the optics from stray light. Each PC requires extensive build time from highly skilled technicians. The PC cylindrical aluminum ribs (or blades) are individually attached to alignment frames. This hands-on "place/weld/measure and repeat" process is ineffective for the thousands of ribs. Build times have exceeded a year, and sometimes the PC still failed to perform. Some telescopes scrap the PC early to avoid these complications and accept the limitations in performance.

Eliminating the hands-on time with CNC unattended wire EDM automates the build, but can't reach the thin walls required. Chemical milling of this large, complex structure is an innovation which will bring fast and affordable PC to market.

Current chemical milling uses HF and HNO3 acids to etch thin films of Titanium. However, etching is traditionally done on thin sheets. Mindrum Precision process will investigate etching of this complex material. New concentration levels, etch times, and agitation methods will be explored to achieve a uniform etch along the entire length of the numerous 3" slots.

Mindrum Precision will combine wire EDM with Chemical Milling to rapidly make affordable precollimators for future telescopes.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Some telescopes are unable to afford a precollimator due to budget or weight constraints. This limitation handicaps the telescopes' ability to see farther with greater clarity. Decreasing the build time from 12 months down to 1-2 months will greatly reduce cost and time constraints for future telescopes. Chemical milling has the potential to also reduce the overall weight of titanium or aluminum precollimators.

All future XRT missions that utilize a PC would all benefit, samples of these NASA missions include NuSTAR, WHIMEX and SMART-X.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
There is a chronic need for precollimators for all space-based x-ray telescopes and thus this innovation would potentially support all of them with an entirely new way of manufacturing the stray-light shielding structure. Non-NASA missions that would be positively affected would be ones like ESA's Athena and JAXA's ASTRO-EII, ASTROH,
DIOS and FFAST, all of which are XRT missions that utilize a precollimator.
