About this file
This document is a Recommendation and Determination to Solicit from One Source or Brand Name. It recommends that NASA, NASA Shared Services Center negotiate with Eksma Optics only for the purchase of three pairs of potassium titanyl phosphate (KTP) crystals, at an estimated total cost of and an estimated delivery time of 8-9 weeks. The justification is that the NewAthena X-ray Integral Field Unit (X-IFU) detector calibration team requires these specific KTP crystals, which Eksma Optics is the only known vendor able to provide. Using a different vendor or brand would severely compromise the performance and calibration of the critical spectrometers for the New Athea flagship mission. This recommendation is associated with a related federal contract opportunity, Solicitation Number 80NSSC24881124Q, which is a sole source requirement for the same KTP crystals from the NASA Shared Services Center.

NASA SHARED SERVICES CENTER
RECOMMENDATION AND DETERMINATION TO SOLICIT FROM ONE SOURCE
OR BRAND NAME
PICK ONE
Sole Source:
☒I recommend that NASA, NASA Shared Services Center negotiate with Eksma Optics only for the purchase of three pairs of potassium titanyl phosphate (KTP) crystals. The total estimated cost of this effort is and the estimated period of performance or lead-time for delivery is 8-9 weeks ARO.
OR
Brand Name Justification:
☐I recommend that NASA, NASA Shared Services Center negotiate with only with vendors who can provide the subject brand name from Manufacture Name for Enter Supply or Service to be procured. The total estimated cost of this effort is Enter Dollar amount and the estimated period of performance or lead-time for delivery is Date.
This recommendation is for the acquisition of supplies or services determined to be reasonably available from only one source/only one manufacture. Competition is impractical for the following reasons (please answer the questions below):
1. What are the reasons for soliciting only the suggested source/suggested brand name? Please provide the unique characteristics of the items or services along with the supporting rationale and the market research performed to substantiate your reason for the suggested source/brand name.
The NewAthena X-ray Integral Field Unit (X-IFU) detector calibration team requires channel-cut crystals made of potassium titanyl phosphate (KTP) for a 1.5 keV monochromator. This the cheaper of only two vendors that we are aware of that sell this type of crystal. We contacted a number of companies but no other was able to provide it. We previously purchased and two crystals from this vendor in 2022 and measurements have demonstrated that the crystals meet the requirement for the 1.5 keV monochromator. We can only be certain that the crystals provided by Eksma are able to produce the reflectivitity and high spectral resolving power intrinsic to this crystal type that is needed for the NewAthena project from our prior procurement and extensive and complicated testing by our team.
2. What is the impact to the government if another vendor/brand is used? Include any dollar, schedule, or compatibility impacts if possible.
The performance of the calibration spectrometers developed would be far less, and thus the calibration of the detectors for this critical contribution by NASA to the New Athea flagship mission would be severely compromised.
