Work Package Descriptions

The conceptual architecture [Phase A] has been converted to separate work packages and each of these will be studied. The interaction between the work packages will be controlled by the systems engineering team.

 

  • Simulations (SIM)

The goal of this workpackage is to conduct end-to-end science simulations to assist science trade-offs on the TLRs and provide the tools necessary to  design the MOSAIC Reference Surveys.

  • Data Reduction Software (DRS)

The DRS will look at the requirements for the calibration and seek to inform the other sub- system designers of the impact on the observations of some of the trade-off decisions. This will be done by modelling of the system.

  • Systems Engineering

The systems engineering team will manage the interaction between the sub-systems and between the science and technical teams. The overall light path and calibration system designs will be included in this work package.

  • Instrument Core Sub-System (ICOS)

Design of the overall structure implementation. Manages the telescope mechanical interfaces and ensures that the flexure and field tracking are within the requirements identified from the other work-packages. In implementations which require a carousel, this will be part of this work package.

Cable routing between the other sub-systems will be managed here.

  • Science Optical Signal Correction (SOSC)

SOSC will be in charge of defining the Adaptive Optics configuration that will allow meeting the specifications. This includes System activities (simulations and trade offs), components and modules definition and, finally, implementation at the Telescope Focal Plate.

This WP is linked with the POS since it defines the set of components that will have to be installed on the Focal Plate with the needed accuracy. It also gets a link with SOST WP since it delivers the corrected beams with the appropriate format.

This WP is not responsible for HMM & IGM definition except through the definition of a GLAO mode using M4 only.

  • Positioning Sub-System (POS)

POS will define the way all pick offs (whatever the mode: HMM, HDM,IGM) will be installed on the focal plate with the needed accuracy. It will be highly related to the overall architecture of the instrument.

The configuration time is a highly dependent on this package.Science Optical Signal Transport (SOST)

This WP is responsible for transporting the corrected Science light from the focal plate to the spectrograph. It will include Fibre links (HMM & IGM) and, may be, Fibres or another solution (slicers) for HDM. This is one of the Trade Offs that will be performed in the Phase A study.

  • Spectrograph Sub-System (SPES)

The spectrograph work package will consider possible implementations that cover all of the modes. The best use of detector real estate as well as the fibre feed focal ratio and diameter are key parameters to be considered in this work package. The output will have a significant impact on the overall instrument layout.

  • Electronics and Instrument Control System(EICS)

The instrument mechanisms and cryogenics will be controlled using ESO standard hardware and software. This workpackage is expected to be low risk but a study of the control system will be made to assess the likely space, power and layout implications.
