The objective of this project is to deliver the WEAVE instrument, a new wide-field spectroscopy facility for the prime focus of the 4.2-m William Herschel Telescope. This project will comprise the delivery of a new two-degree field of view prime focus corrector, a 1000-multiplex fibre positioner and a dual-beam spectrograph. A small number of individually deployable integral field units and a large single integral field unit will also be available within the fibre positioner. Both the IFUs and the MOS fibres will feed the spectrograph that will provide full coverage of the majority of the visible spectrum. The project will include all deliverables necessary so that the ING may operate the instrument in fulfilment of the scientific objectives.
A fundamental premise for the instrument construction is that development work will only be carried out when no other alternative exists for producing the constituent products, and such development work will be kept to the minimum required to deliver the project. Thus, where possible, the use of commercial-off-the-shelf products will be preferred. This has the advantage of reducing the project costs and allowing the project and the end product to benefit from tried-and-tested technologies that are often widely available. For specialised services and products, the project will endeavour to seek such items from within the technical capabilities of the consortium provided that this is a cost-effective and efficient solution. Likewise, the project will be managed entirely from within the consortium.
The WEAVE Project will deliver the fibre-fed MOS instrument for the WHT consisting of the fibre positioner, the spectrograph, the instrument control software, the science data processing software and the data management and archiving system. The enhanced prime focus corrector will also be delivered as part of this project. It will also provide the observatory operational model required to support science data delivery following project closure.
Exclusion
The project will not deliver the science, as this is out of scope of this particular project. Delivery of the science will be addressed in conjunction with the ING Board, the Project Board and the observatory.
The project will be structured into a pre-project stage, followed by five managerial stages each with its own detailed plan. The pre-project stage will focus on starting up the project by assembling the Project Management Team, defining how the project will be approached, defining the project files and controls, initiating development of the WEAVE science cases and establishing an initial breakdown structure to assign work to the Project Team.
The project stages are snow below:
Stage | Description |
1 | Capturing requirements and delivery specifications |
2 | Preliminary design stage followed by a preliminary design review |
3 | Final design stage followed by a final design review and procurement of long-lead time items |
4 | Manufacturing, assembly, integration and testing |
5 | Commissioning, operational handover and project closure |
