There are "Final Bidder Questions" asked.
please find beside Q. and A.


Q1. Acceptance, payment and Guarantee

The Offer Form, Section 6, states "30 Days after delivery and acceptance". The General Terms and Conditions of Purchase, Section 10(c), and the General Specification, Sections 5.2 and 5.3.6, refer to different acceptance stages.
Please confirm that, for the NDMs, contractual acceptance takes place no later than completion of SAT Aa after delivery and is not dependent on SAT Ab, SAT Ba or SAT Bb/beam availability.
A. SAT Aa will be within ~ 1 week after delivery which then is the date of acceptance. SAT Ab will be done by us later. -> Payment after SAT Aa


Q. Please also confirm that this acceptance is relevant for risk transfer under Section 10(b), payment under Section 12 and Offer Form Section 6, and starts the 24-month Guarantee under Offer Form Section 10.
A. Yes


Q. For better preparation of offer, please state the exact acceptance milestone and the maximum period after delivery for acceptance.
A. Delivery -> 1week -> SAT Aa and Acceptance by SRP -> X days -> Payment


Q2. 48-month contract term

Please confirm that the 48-month period stated in Offer Form Section 3 only refers to the maximum overall contract term and does not delay acceptance, payment or the start of the Guarantee for delivered units.
A. Yes


Q3. Option A and delivery schedule

Please clarify whether "Option A is expected to be call off until 31.12.2026" means that the call-off order must be placed by 31 December 2026 or that the seven units must be delivered by that date.
For the 63 units under the Main Contract, please confirm whether batch deliveries are permitted. If yes, please provide the preferred batch sizes/dates and confirm separate acceptance, invoicing and payment for each batch.

A. call-of order
batch delivery acceptable with separate acceptance,...
Batch size is depending on possible delivery dates but at least 15-20 devices per batch due to logistical effort (SAT Aa at Weiterstadt, documentation, etc.) within 2026 we are flexible concerning delivery dates up to mid of December.
Delivery in 2027 must be discussed in detail if necessary.


Q4. CID labelling

Order Specification, Section 4, states that the CID label shall be delivered separately with the NDMs but shall not be attached to them. General Specification, Section 8.3.1, states that each FAIR component shall be labelled by the Contractor.
Please confirm that, for the NDMs, the specific requirement of Order Specification Section 4 applies, i.e. the Contractor shall supply the CID labels separately but is not responsible for attaching them.
A. Yes, only loose labels, we attach them


Q .Please also confirm that the CIDs listed in Table 2 are final and provide the applicable label design and any NDM-specific requirements for material, durability and scanability.
A. The CIDs are fix. But requirements for material, durability and scanability is not mentioned in the Order Spec but in the technical guideline. But a simple foiled sticker readable by e.g. smartphone is ok.


Q. Please confirm that delays caused by missing or late Company-provided information or specifications will not be attributed to the Contractor and will extend the affected delivery dates accordingly.
A. If specific information is required, like e.g. the cable length this will only affect the delivery date of the corresponding device type/batch or unit not the general delivery of not affected units.


Q. In the technical guideline for the Component CID in 3.1 you define that the CID labels should only be created by approved users. Who approves users / contractors?
A. The CIDs were created by us. To guarantee readability and correct form a single label (first of series or prototype or random) should be send to us by mail that we can check the form and content. But this is no approval only crosscheck. -> Approval not required

Dear bidder,
there are 2 more Questions and Answers.

In neutron dosimetry, there are, in principle-and currently especially so-some fundamental issues, particularly in the energy range above 7 MeV. For neutrons, weighting factors are used that evaluate the energy of the neutrons either in discrete steps or as a function of energy. This sometimes results in factors that vary between energy ranges. Furthermore, since neutrons interact strongly with their surroundings, the displayed dose value can vary by a factor depending on temperature and, in particular, humidity.

For energies above 7 MeV, the ongoing discussion regarding dose quantities is also of interest. Since different nuclear reaction mechanisms involving secondary particle fields occur above 7 MeV, this aspect is particularly important for evaluating a dose rate meter. These fundamentals are the reason why no conformity assessment of neutron dose rate meters can be performed.

In addition, fluctuations in the natural background due to variable solar activity can be observed, which, if properly accounted for in the calculation of detection limits, have a negative effect. Verification of such measuring devices using high-energy monoenergetic neutrons is not possible due to a lack of sources.

This raises the following questions:
Q 1. Should the devices be calibrated in accordance with the old or the new dose quantity definition?

A 1. The devices must be calibrated in accordance with the new dose quantity definition.

Q 2. How should the displayed or calculated dose rate values be verified against the actual dose, and how should the calibration be performed?

A 2. The response of the dosimeter should correspond as closely as possible to the fluence-to-ambient-dose conversion coefficients. Calibration must be performed using an AmBe or Cf-252 neutron source. The response characteristics should be determined using Monte Carlo simulations (e.g., MCNP). In addition, the detectors should, if possible, be experimentally verified in well-characterized radiation fields, such as those at CERF, or in (quasi-)monoenergetic neutron fields, such as those available at iThemba LABS or the PTB.

Dear bidder

here we have additonal Q&A

TECHNICAL
Q:For Option Main Contract (63 NPM), Option A(7) and Option B(8) for NPMs with standard connectivity to FHT6020:
The text implies that this is for just the neutron probe without an FHT6020 as it states that the company already owns those. So, is it correct, the offer is just for the NPM probe and the standard connector cable in various lengths (compromising 500m in total), no additional FHT6020 or FHT6020 units with special firmware for neutron pulse capabilities are part of this tender ?

A:Correct only probe, cables and wall mounting option, no FHT6020 devices, only compatibility to them.


COMMERCIAL
Q. Please clarify whether the MRI deduction of 0.8% shown in the price sheets is only used for the evaluation / awarding price, or whether it will also be deducted from the contractual remuneration / invoice amount payable to the contractor.

A: As specified in the offer form, the MRI 0,8% is deducted from the total amount, resulting in the contract award price (which then corresponds to the invoice amount).


Best regards

Dear Sir or Madam,

We have received bidder questions that we answer herewith:

1. Which model should be used to calculate the detection limit, and what type of substrate is assumed, taking into account the shielding effect of the building material used and the intrinsic activity of the concrete?
Over what measurement period should the detection limit be reached?
Determining the detection limit is not required. The measurement range must be at least 10 nSv/h and up to 100 mSv/h. The installation locations vary greatly; in the most extreme case, the background radiation at the Earth"s surface (open sky) is high, while inside buildings it is sometimes heavily shielded (typically by concrete with virtually no intrinsic activity). The installation locations are outside the primary shielding of the accelerator areas (i.e., outside restricted areas) and therefore have low background radiation (no activation of the surrounding environment).
The measurement time for this is typically 1 second.


2. Does the measurement system need to be designed for pulsed neutron radiation? What pulse duration should be expected?
Yes, it must be sensitive to pulsed neutron radiation. Pulse durations typically range from 1 microsecond to 10 seconds.


3. Can you please disclose all interface parameters (electrical, functional, and software)?
Electrical parameters: The output interface from the monitor is expected to consist of TTL pulses corresponding to the received neutron dose rate. The TTL pulses will be processed by custom electronics that also provide the bias voltage.
Functional parameters: As described in the specification
Software: The device must be interfaced via a dedicated, in-house developed software module in EPICS. If the interface is non-standard, a detailed interface protocol description is required to adapt the software module.


For further questions please do not hesitate to contact us.

Kind regards
Elena Reitz
