- Description
- Amendment III: The purpose of this Amendment is to up minimum specification 3 as follows: From: 3. Sensor window: polymer for low energy X-ray transmission To: 3. Sensor window: must be light tight but allow transmission of low energy X-ray, at least 10% at 0.4 keV All other terms and conditions remain unchanged.� Please see attachment B-3 Amendment III for complete details.� Amendment II: The purpose of this Amendment is to extend the due date/time for quotations due to the fact no quotations were received. The due date/time for quotations is hereby extended as follows: From:� August 23, 2021 @ 12pm EST To: August 27, 27, 2021 at 3pm EST All other terms and conditions remain unchanged.� Amendment I: The purpose of this Amendment is to address vendor questions received in regard to the requirements. See below: Question: Can you please confirm the kV required for the source/tube? Answer:� To clarify, we do not need an x-ray source or tube.� We already have a device called EBIT that produces X-ray from highly charged ions. We require an x-ray detector that can be used to observe the broad spectrum of X-ray emissions from our EBIT device.� The operation of the EBIT is variable, producing X-rays with energies from 0.2 keV to 10 keV, depending on the electron beam energy selected. Question: Do you require a probe, if so what length? Answer:�� The detector must be mountable within the vacuum chamber.� No specific probe is required, but details must be provided for mounting the detector and its integrated heat sink. ��NIST will use the mounting information to make the appropriate adapter to the EBIT device. Question: Is this a modular design to be mounted inside the vacuum chamber? Answer:��� The detector and its integrated heat sink will be mounted as close as possible to the aperture from which X-ray is emitted by the EBIT. It seems clear that the detector and heat sink must be modular.� To get as close as possible to this x-ray emission aperture, the detector/heatsink package must be mountable within the vacuum fitting for the viewport, which is on a 4.5� Conflat flange. ��� Question: How do you intend to mount the detector? Answer:��� The detector along with its heat sink must have mounting features, which NIST will use to fasten it to an alignment structure designed to optimize light collection from the EBIT.� Mechanical details of the detector mounting mechanism must be provided so that NIST can build the adapter. All other terms and conditions remain unchanged. HIGH RESOLUTION X-RAY DETECTOR per the requirements as set forth in the attached combined synopsis/solicitation.� See attachment for complete details.�
