A team from the 4MOST Project Office visited CRAL on 15-16 December 2021 to conduct the Local Acceptance Review (LAR) for the first Low-Resolution Spectrograph (LRS-A). The purpose of the LAR is to assess whether a subsystem is mature and complete before shipping it to the AIP for integration. During the weeks prior to the physical meeting, the deliverable documentation was submitted and reviewed, resulting in a set of comments and questions. At the two-day LAR meeting in Lyon the technical performance and cost were reviewed, the hardware was inspected, the instrument was operated using engineering GUIs, and more. 4MOST project members from MPIA and ESO also participated remotely.
In general, the performance of LRS-A was found to be excellent and no major issues were identified. Issues related to documentation and product assurance are well advanced and on par with expectations at this stage of the project. A list of Action Items has been produced as a result of the LAR. The plan is now for LRS-A to be shipped to Potsdam sometime in Q1 of 2022, with the exact date depending on other system integration activities.
The Project Office wishes to thank the LRS team at CRAL for their dedicated and competent work and superb collaboration. We are already now looking forward to coming back to Lyon when LRS-B is finished!
