- Description
- Amendment #1 This amendment #1 to RFP 206617 is issued to provide answers to offeror generated questions. Specifically this RFP is modified as follows: The following Offeror generated question and corresponding answer are provided Question: #1 Will it be possible to add additional motions and its controls to achieve high performance? Answer: #1 The motions of the KB mirrors and its controls requested for in the technical specifications have been designed to achieve maximum stability. Some movements e.g. roll and yaw for the VFM and yaw for HFM, have been left out intentionally to increase the mechanical stability of the system. Any contractor interested in submitting a proposal shall follow these specifications and submit a proposal accordingly. However, following chapter 8 in the Statement of Work, the contractor is encouraged to make recommendations for changes that might lead to an improvement in performance. Therefore, if it is assumed that additional motions do not reduce the requested stability but improve the performance of the system, the contractor is encouraged to add this to the proposal as an option. Question: #2 In the technical spec 2.3.4.1 e., it is described that the distance between the downstream end of the High Resolution KB HFM and the outer wall of the vacuum vessel shall be less than 1 cm. Considering its UHV use, would it be possible to set it 15 mm to make sure the strength? Answer: #2 The high resolution KB mirror set is aiming for a spatial resolution below 100nm. As a result, the working distance, i.e. the distance between the downstream end of the high resolution HFM and the sample is small, here, 40 mm. Taking into account the known sizes of motors necessary to move and rotate the sample through the focal spot of the KB mirrors, an open space of 30 mm is minimum. This results in the distance of 10 mm written in the technical specifications. As there is not much of a movement in Z-direction necessary for the high resolution HFM, most of this can go into the wall thickness of the vacuum vessel. No optical or mechanical component shall be connected to the vessel wall, therefore a flexing due to vacuum pressure will not harm the performance of the system. By keeping the volume of the vacuum vessel to its minimum necessary size, it is possible to give the body structure of the vessel an irregular shape, which then supports mechanical stability against vacuum pressure. Question: #3 Would you have any specific limit for the distance between the upstream end of the High Resolution KB VFM and the outer wall of the vacuum vessel? Answer: #3 There is no specific limit for that distance. Except as noted herein, all requirements as set forth in RFP solicitation request 206617 remain unchanged. Any questions should be addressed in writing to the attention of George Woods.
