QUESTIONS AND ANSWERS FOR 20-3164

(FIBEROPTIC BUNDLES FOR CXI)

Q1: Can you provide CAD drawings or models of the End A and B parts and the tray so we can better understand the mechanical requirements? Or pictures of an existing assembly?

A1: End B details can be found in the attached CAD Tray.dwg file. Also Fiber_tray_front.jpeg and GA-152_fiber_tray.pdf are attached. End A details are specified in "Attachment B": The ferrule should be an aluminum or stainless steel tube with square cross-section. The length of the tube should be 2". The exterior width of the tube should be 3.1mm, and the wall thickness should be 0.5mm. We do not have CAD drawings or images for this part, only the image provided in the Word document with the specifications ("Attachment B").

Q2: Do you have environmental specifications for this? (temperature, humidity, etc.)

A2: Refer to Answer #1.

Q3: What is meant by “The end of the 4x12 grid is sloped.”?

A3: Refer to Answer #1.

Q4: We cannot guarantee performance in a “moderate neutron/gamma environment”. We can offer an exact fiber type for you to approve based on your experience.

A4: We currently use high-OH fused silica core and polymer cladding.

Q5: It would be difficult to AR coat the ends of the fibers due to the large size of the assembly. Is this a strict requirement? We estimate the transmission without AR coating will be 80-82% at 529nm, including losses in the fiber and losses at both faces. This does not include packing fraction losses.

A5: I would be OK relaxing the AR coating requirement as long as we have the freedom to select a proposal that comes in with higher % transmission by using such a coating, even if it costs extra.
