REVISED STATEMENT OF REQUIREMENTS

Electron flood source (1 eV – > 500 eV)

Background: The contractor shall deliver an electron flood source with controller/power supply and appropriate cables to assist in conducting laboratory experiments.

Scope of Work: Specifically, we are interested in how low energy electrons impact surface chemistry when employed to neutralize surface during XPS. The flood source shall provide a uniform source of electrons to better measure the mechanism and rate of these phenomena in UHV conditions. The instrument shall meet the following minimum specifications:

Electron flood source shall be mountable to a CF70 flange (also known as DN 40) either directly or via adapter Electron flood source shall insert 160 mm into the UHV system Electron flood source shall be operational in the range from 1 eV to 500 eV.

Shall provide a wide range of current densities, at least 5 nA/mm2 to 275 nA/mm2, at the target’s surface.

Electron flood source shall have an operational and uniform current density in an area greater than or equal to 2 mm diameter (or 2 mm x 2 mm) for all energies employed.

Electron flood source shall be operational at pressures < 1 x 10-5 torr (1.3 x 10-3 Pa).

System shall operate using 115 V AC If required for operation, the system shall interface to a computer with either a USB or ethernet connection

Installation: Installation shall be conducted by the TPOC and other NIST staff.

Delivery Date: The contractor shall deliver the electron flood source no later than 6-12 weeks after the date of award.

Place of Delivery: All instrument manufacture and preparation shall be completed at the Contractor’s facility. Delivery of the instrument shall be at the NIST, Gaithersburg, Maryland during normal business hours. Normal business hours are Monday through Friday, 8:30 a.m. to 5:00 p.m. Eastern Time with the exception of Federal holidays or other official closures.

Warranty: The Contractor shall provide, at a minimum, a one-year warranty for the electron flood source. The warranty shall cover all parts, labor and travel. The warranty shall commence upon successful completion of delivery.

Acceptance Criteria: Final acceptance by the Government shall be granted after confirmation that the equipment meets all requirements of the statement of requirements. The warranty shall not commence until final acceptance has been granted by the Government. Should any deficiencies be noted prior to final acceptance, the Contractor will be notified and provided the opportunity to correct all deficiencies, at their expense, in accordance with the commercial terms and conditions of the contract.
