Project Objective

The Center for Functional Nanomaterials (CFN) will partner with the contract to build a low-temperature (LT) scanning probe microscope (SPM) using an existing cryostat. The LT-SPM will be integrated into the existing multiprobe ultra-high-vacuum (UHV) surface analysis system at CFN. Integration of the LT-SPM with the existing room-temperature to high-temperature STM (RT HT STM) will extend STM operation over a temperature range from approximately 5 K to 500 K and will add new capabilities, including atomic force microscopy (AFM) and electrical transport measurements at ~5 K.

These enhancements will provide significant new capabilities for the user and scientific communities, particularly in quantum informatiolckln science (QIS), nanoscience, two-dimensional functional materials research, and surface science. The project is designed to preserve all original functionalities and capabilities of the system that have demonstrated excellent performance, ensuring that none of these are compromised or sacrificed, and avoiding any prolonged system shutdown that would impact the user community.

Project Scope This SOW covers the following activities.

The contract supports the design and implementation of a low-temperature scanning probe microscope (LT-SPM) and its integration into the existing multiprobe system without compromising or sacrificing any original system functionality. The LT-SPM will include a new SPM scanner, a sample stage with seven additional electrical contacts, a removable magnetic field assembly, required internal electronics, and all necessary wiring and cabling, while utilizing an existing cryostat previously purchased from the same Supplier for a prior LT-STM system. All SPM cabling will be compatible with the existing Scienta Omicron MATRIX SPM controller.

NOTE: Clauses 3.2 through 3.22 apply to all POs and will be included collectively in other procurement documentation when required/specified.

3.2 Assessment by Buyer

The Supplier’s quality system is subject to assessments by the Buyer’s Representative(s) for conformance with the requirements of the PO. Supplier or Distributor must allow BSA representatives, BSA customers, and regulatory agencies right of entry into the Supplier’s facilities to determine and verify product, processes, records, personnel, material, procedures, and systems.

3.3 Change Approval

No change(s) are permitted to be made to any Buyer requirements, (e.g. part number, model number, etc.) without the prior written approval of the Buyer.

3.4 Responsibility for Subcontractors

It is the responsibility of the Supplier to impose applicable requirements from this document upon their subcontractors.

Additionally, the Buyer reserves the right to disapprove, in writing, any subcontractor. For nuclear facility requirements per NQA-1, the Supplier must incorporate NQA-1 requirements in sub-tier procurement documents.

3.5 Responsibility for Conformance

The Supplier is responsible to provide items that conform to the requirements of the PO regardless of any assessments, surveillances, inspections and/or tests by the Buyer or its representatives at either the Supplier’ or Buyer’s facility. The Buyer reserves the right to request failure analysis and corrective action for non-conforming articles or items submitted or supplied to the Buyer. The Supplier is responsible for notifying the Buyer of any recalls or alerts associated with this

PO.

When NQA-1 requirements are imposed, prior to shipment, the Supplier must report any nonconformance that cannot be corrected to full conformance and obtain approval from BNL for possible Use-As-Is or Repair dispositions. Additionally, for commercial grade services, a service performance record must be provided that documents the adequacy of the service performed to the identified critical characteristics documented in the PO/contract.

3.6 Protection of Material and Equipment

The Supplier must employ procedures that assure adequate protection of material and equipment during shipment and while in storage. Such protection must include special environmental packaging, as necessary. All items shipped (originally packaged or repackaged) to BNL or other locations cited in the PO or contract, must comply with the requirements for preservation, packaging and marking as stated in the latest revision of ASTM Standard D 3951 Standard Practice for Commercial Packaging.
