STATEMENT OF WORK

Objective/Requirements

KSC requires the monitoring of hypergolic materials at American Conference of Governmental Industrial Hygienist

(ACGIH) limits, per KNPR 1840.19 and KNPR 8715.3. Current capability can reach the 10 ppb ACGIH limits but cannot maintain the detection limits without drifting over a two-to-four-week period. Per KNPR 8730.1, the end-of-period reliability for measuring and test equipment (MTE) shall not be below 90%; therefore, drift leads to the need for frequent calibration and increases unreliability. In order to meet the KSC requirements, this work will develop an advanced, tandem differential mobility spectrometer (DMS) for hypergol detection with a goal of maintaining the calibration over a 90-day period with +/- 25% accuracy at 10 ppm. Ideally, quantitation can occur at 10 ppm hydrazine and monomethylhydrazine.

shall perform the following:

Task 1: Simulation software shall be used to analyze and optimize the dual polarity plasma source design for maximum ion flow in air under atmospheric conditions.

Task 2: Once the simulated design has been optimized, a prototype dual polarity plasma ion source shall be constructed to interface with the dual stage analyzer to prepare it for quantitative testing. Knowing that the final sensor will be exposed to hydrazine and MMH, appropriate chemicals shall be utilized to evaluate the performance of the dual polarity plasma ion source compared to the Ni-63 source.

Task 3: shall be available to provide on-site support integration and testing of the Dual Polarity

Plasma Ion Source to the GP Ionics Team. The deliverable is a Dual Polarity Plasma Ion Source system for integration into GP Ionics Tandem DMS instrument, interface drawings, and operating instructions.

shall ensure delivery of the ionizer has been received by GPIonics by the target delivery date. The target delivery date is currently set as 8/1/2023. The target delivery date may be adjusted upon written agreement (e-mail is acceptable) between and GPIonics and with written approval (e-mail is acceptable) of NASA PI. It is the responsibility of to collaborate with GPIonics such that the ionizer is integrated in a timely manner such that instrument delivery to KSC is met.

The integrated bread board dual polarity plasma source integrated with the GP ionics tandem DMS instrument is due at Kennedy Space Center no later than January 15, 2024.

Task 4: shall support bi-weekly meetings, telecons or status updates as well as a management final review. shall provide monthly update reports to capture progress. shall prepare a final project summary to capture status due no later than February 21, 2024. Task includes labor to support telecons, meetings and reporting.
