LRS Mid-Term Review

On 10 – 11 July 2019 the Project Office visited CRAL in Lyon to meet with the Low Resolution Spectrograph (LRS) team for the project-internal Mid-Term Review (MTR). This was the fifth MTR with more to follow. The purpose of this review is to assess the status of the work package – schedule, finances, product assurance, MAIT, interfaces, technical performance, and compliance matrix – approximately half-way between the Final Design Review and the Local Acceptance Review. The review panel (Brynnel, Giannone, Bellido, Frey, and Johl) concluded that the work package is in general performing very well, and no major issues were identified. During the mandatory lab visit, the review panel could see the two LRS optical tables assembled and integration and verification of the mounts for the optics in progress. ESO has already delivered the cryo-vacuum system and MPIA has delivered the control electronics. AIP will deliver three science-grade detectors in late July. The delivery of optics from various vendors remains on the critical path for the MAIT of the two LRSs. CRAL is actively monitoring these deliveries, and in spite of some delays the dates for the Local Acceptance Reviews of LRS-A and LRS-B were confirmed.

The Project Office would like to warmly thank the CRAL team for the excellent preparation of the LAR and for hosting us during the review.
