Amendment I (SB1341-16-RQ-0256)

The solicitation is hereby amended to address vendor questions, update General System Requirement #3 and to extend the due date for quotations as follows:

Questions/Answers:

Question: The technical specification sometimes refers to +/- 5T, is a bipolar operation (a bipolar power supply) essential?

Answer: See revised Specification 3 below

Question: Is there a stability level that is required?

Answer: See revised Specification 3 below

The following is a change in the General System Requirement #3:

FROM:

3. Sample space and Magnet: A sample space within a minimum ±5 Tesla superconducting magnet will be provided. Magnet shall be able to run in persistent mode. As part of the requirement of a cryogen-free system, the superconducting magnet must be cryogen-free. The sample space must have a minimum diameter of 20 mm and a maximum acceptable magnetic field inhomogeneity of 0.1% within a 10 mm diameter spherical volume. Sample holder shall be customer specified pinout. Sample does not need to be immediately accessible.

Sample holder shall be customer specified pinout. Sample does not need to be immediately accessible. The system must be bipolar – that is, plus and minus 5 Telsa operation. The stability on the magnetic power supply shall be at or better than 0.02%.

The due date for quotations has been extended as follows:

FROM: April 19, 2016 @ 12 noon EST TO: April 26, 2016 All other solicitation terms and conditions remain unchanged.
