- Description
- The above referenced solicitation is hereby amended to respond to technical questions submitted and to extend the due date for proposals. 1. The due date for proposals is hereby changed as follows: FROM: April 16, 2004 at 3:00 PM Local Time TO: April 30, 2004 at 3:00 PM Local Time 2. Responses are provided to the following technical questions: QUESTION: What environmental conditions will be guaranteed by NIST during the acceptance testing at SURF? Please include: a. SURF electron beam stability - positional and angular; how and with what precision will this be verified during testing? b. Average temperature and temperature stability in the room housing SURF III, the pre optic(s), and entrance slit. c. Average temperature and temperature stability in the room housing the EUVL monochromator, diverting mirror, and exit slit. d. Vibrational spectrum up to 100Hz for the room housing SURF III, the preoptic(s), and entrance slit; how and with what precision will this be verified during testing? e. Vibrational spectrum up to 100Hz for the room housing the EUVL monochromator, diverting mirror, and exit slit; how and with what precision will this be verified during testing? RESPONSE: This is not relevant. The specifications do not require any performance standards for the entire instrument, but just the chamber and interior parts to be constructed by the vendor. The specifications concern only the dimensional and angular stability of the interior parts (mirror and grating) under the varying vacuum forces impressed on the chamber and the resolution and reproducibility of the angular orientation of the gratings relative to the base on which they are mounted. QUESTION: In the solicitation you state that the "assembled unit will be tested ...initially for one week." Do you intend to perform stability tests on each grating for one full week (7 days), or will one week suffice for both gratings? Please clarify. RESPONSE: One week for both gratings. QUESTION: Is point 'C 1.3.5. Data Acquisition Software' intended to be part of this request? RESPONSE: No. QUESTION: Please furnish the missing thickness dimension of the diffraction gratings and toroidal pre-mirror. The sizes of these optics constrain the grating and mirror mount designs. RESPONSE: These can and will be provided, via a subsequent solicitation amendment next week. QUESTION: For ray trace and design analysis, please furnish copies of the complete metrology data and metrology reports for the optical elements to be used in this beam line after the upgrade. RESPONSE: These can and will be provided, via a subsequent solicitation amendment next week. QUESTION: Please provide 'as built' specifications for the existing entrance slit, exit slit, mirror mounts, and support structures that will be supplied by NIST and incorporated in this beamline after the upgrade. Ideally, this data will include: long-term stability, short-term stability, adjustability, shifts due to atmospheric load under vacuum, repeatability and accuracy of adjustments, degrees of freedom for alignment, location and precision of fiducials on components for alignment. RESPONSE: This is not relevant.The specifications do not require any performance standards for the entire instrument, but just the chamber and interior parts to be constructed by the vendor. The specifications concern only the dimensional and angular stability of the interior parts (mirror and grating) under the varying vacuum forces impressed on the chamber and the resolution and reproducibility of the angular orientation of the gratings relative to the base on which they are mounted. QUESTION: The exit slit was mounted on a projecting beam or member supported at only one end; Modifications were intended to reduce vibrational effects. What is the status? RESPONSE: This is not relevant. The specifications do not require any performance standards for the entire instrument, but just the chamber and interior parts to be constructed by the vendor. The specifications concern only the dimensional and angular stability of the interior parts (mirror and grating) under the varying vacuum forces impressed on the chamber and the resolution and reproducibility of the angular orientation of the gratings relative to the base on which they are mounted. QUESTION: In the event that problems with NIST supplied components are discovered during acceptance tests, please confirm that the intent is for the contractor to provide all necessary labor and materials to remedy all problems at no additional cost to the Government. Refer to the bottom of page 9. RESPONSE: This is not relevant. The specifications do not require any performance standards for the entire instrument, but just the chamber and interior parts to be constructed by the vendor. The specifications concern only the dimensional and angular stability of the interior parts (mirror and grating) under the varying vacuum forces impressed on the chamber and the resolution and reproducibility of the angular orientation of the gratings relative to the base on which they are mounted. QUESTION: In the event that environmental conditions during acceptance tests at SURF are not within the range guaranteed by NIST (refer to item 1.), will NIST pay for the additional costs incurred during completion of the testing? RESPONSE: This is not relevant. The specifications to not require any perfomance standards for the entire instrument, but just the chamber and interior parts to be constructed by the vendor. The specifications concern only the dimensional and angular stability of the interior parts (mirror and grating) under the varying vacuum forces impressed on the chamber and the resolution and reproducibility of the angular orientation of the gratings relative to the base on which they are mounted.
