Preliminary design documents

About PDR

The PFS team successfully completed a Conceptual Design Review held 2012 March 19. There we showed that our conceptual design meets the preliminary requirements and that the interfaces are workable. We also presented a clear plan to refine and mature the requirements and interfaces, as well as plans to complete the design, analyses, test, and integration activities that are consistent with the project resources and risk posture.

Based on eleven months of our work since this milestone, we, the PFS team, will have a Preliminary Design Review (PDR) on 2013 February 25th and 26th at Subaru observatory in Hilo, Hawaii. Although it is an internal event, the reviewing will be carried out by external reviewers, just as we did for the CoDR, in order that the PFS team can receive independent and objective comments and suggestions and to make improvements based on them.

During this two-day review, we will present overall designs and demonstrate readiness to proceed to detailed designs. We will also demonstrate how the system acts together as a whole to meet the project requirements. (see PDR objectives below for more details) To accomplish this, we will focus in more detail on technical and management aspects than we did in the CoDR, although we will present an overview of the whole project for the benefit of new reviewers. We will also discuss in some detail the requirements derived from the scientific program for the instrument and their flowdown to the instrument requirements. In the Preliminary Design phase, we have carried out several tradeoff studies in which two or more subcomponents (and institutions) are involved. We expect helpful comments from experienced reviewers on some unresolved tradeoff issues, based on our intensive studies presented in the review. We also would like to have their advice on issues specific to our project, e.g, the instrument integration and maintenance in a project with this scale of international collaboration.

The PDR dates have been set based on Subaru Observatory and NAOJ schedules so that we can share this opportunity with the Subaru directorate, astronomers, and engineers as well as NAOJ staff members. After our successful completion of the PDR, NAOJ will organize a review on the PFS instrument particularly focused on management aspects. The PFS team will try to include issues related to the NAOJ review objectives as much as is possible also in the PDR.
