Please answer the following:
1. Describe the characteristics and requirements of the Detector Array (or the
Telescope Array), including its planned modes of operation (giving performance,
energy threshold, etc. for each mode) and the manufacture and alignment
requirements for each detector component. Include a description of the design and
a summary of the estimated performance of each telescope or detector element. ,
f. Describe any telescopes with multiple reflective surfaces completely. Indicate
why the specific geometry or implementation was chosen. Provide ray trace
diagrams where appropriate. For arrays, state/describe if the array is
reconfigurable. Please fill out the Telescope/Detector Array Characteristics
2. Discuss the lifetime of the facility and any future upgrades. Outline plans for
decommissioning when the activity is finished.
3. Provide a description and an overall assessment of the technical maturity of the
critical components, fabrication techniques, alignment, , and support structure.
Provide a rationale and an assessment of the technical maturity of each key
component or method (off-the-shelf hardware, hardware demonstrated on other
systems, extrapolation from demonstrated technology or implementations,
requires new development of existing technology, requires new technology
development). In particular, describe fully any required new technologies or
developments or open implementation issues required for success.
4. For segmented telescopes, describe in detail the individual segment including the
design (size, weight, surface requirements etc), type of construction, light-
weighting technology required, fabrication techniques, investment required to
produce large numbers (facility construction etc) and the support structure.
Discuss alignment and pointing method knowledge and accuracy.
5. Identify and describe the three lowest technical maturity components, and explain
how and when these components will be demonstrated in reduced-scale and/or
6. What are the three greatest risks to cost, schedule, and performance?
7. Describe the telescope/detector construction and assembly methods. Indicate any
unique construction and any special issues regarding the facility location. This
may be included in Facility Construction section.
8. Address to the extent possible the specific accommodation of the instruments. In
particular, identify any challenging or non-standard requirements (alignment
and/or pointing considerations, thermal environment/temperature limits etc).
9. Describe any aspect of the design or implementation that requires non-US
