About this file
This document is a Specification for an aberration-corrected scanning/transmission electron microscope (S/TEM) that the Company is seeking to purchase for its sustainable transportation program. The S/TEM must meet detailed technical requirements, including demonstrated image resolution at operating voltages of 60kV, 80kV, 200kV and 300kV, and be equipped with specific components such as a cold field emission gun, segmented detector, integrated EDS system, and Gatan Continuum electron energy loss spectrometer. The bid must include a pre-shipment performance demonstration, delivery by December 31, 2025, warranty and service contract details, and pricing terms of DDP (Delivery Duty Paid). The related federal contract opportunity, Solicitation Number PR278566, is for the procurement of this aberration-corrected S/TEM, to be issued by the Department of Energy.

SPECIFICATION - ABERRATION-CORRECTED S/TEM – May 2024
The Company is seeking to purchase an aberration-corrected (probe) analytical scanning transmission electron microscope (S/TEM) for the sustainable transportation program of the Company. This new analytical
S/TEM shall include each the following capabilities and shall meet the listed technical specifications for full operation:
1. Aberration-corrected S/TEM shall be operable and include factory alignments, in both TEM and STEM modes, at the following four voltages and demonstrate (show factory proof) that operation of the microscope at each voltage can achieve the image resolution. Vendor shall identify procedure by which this specification will be met:
- 60kV with demonstrated image resolution at or below 1.3 Å
- 80kV with demonstrated image resolution at or below 1.1 Å
- 200kV with demonstrated image resolution at or below 0.8 Å
- 300kV with demonstrated image resolution at or below 0.7 Å
2. S/TEM shall be equipped with a pole piece having a gap size of >4.0mm.
3. S/TEM shall be equipped with a cold field emission gun
(Cold-FEG) that recovers quickly after flashing (within 1 min.).
4. S/TEM shall be configured with a segmented detector containing a minimum of 8 segments.
5. S/TEM shall include integrated windowless silicon drift detector
EDS system with a geometric solid angle >2.0sr.
7. S/TEM shall be equipped with a Gatan Continuum electron energy loss spectrometer (EELS), and associated Gatan software with EELS and EDS spectrum imaging packages.
8. Alignment of Gatan Continum at each of the required operating voltages specified in #1 - 60kV, 80kV, 200kV and 300kV.
9. Standard specimen holders that shall be included with S/TEM:
- Single tilt holder
- Low-background double tilt holder optimized for EDS system
10. S/TEM shall be equipped with a high-speed CMOS camera with a minimum acquisition rate of 40 fps at a resolution of 4k x 4k pixels.
12. S/TEM shall be fully operational remotely from an adjacent room such that column can be isolated - shall include all consoles and cables to enable remote operation. Bid shall include a detailed explanation of required modifications, if any, to room dimensions to accommodate instrument (and auxiliary components) within the provided room footprint (see Addendum A for room dimensions)
13. Purchase price shall include the following costs:
- NRTL certification of ALL components prior to delivery of instrument
- Site survey
- All shipping and transportation costs
- All import tariffs
- Week long Training
14. Instrument shall be an oil-pump free vacuum system.
15. Bid shall include a Pre-shipment Performance Demonstration of resolution performance (item 1), EDS performance (item 5), and EELS performance
(item 8) at previously specified voltages.
16. Bid shall include estimated instrument delivery date and be delivered by
December 31st, 2025.
17. Bid shall include warranty details and service contract details after warranty expires.
18. Bid shall be DDP (Delivery Duty Paid).
