SPICA FPI envelopes – current status

16th April, 2010Hideo Matsuhara On behalf of FPI team

About the 3D file delivered on 16th Apr. 2010

FPI_ASM_IOB(Trass)_Envelope(FPC)_New.zip Yellow: IOB

proposed structure satisfying the FPIA stiffness requirement with top/bottom/side plates made of Aluminum

Interferes SAFARI envelope (!) Too heavy!

White/gray : MIRACLE – now the optics are updated. The CAD model now also includes Filter & Slit wheels, etc.(mostly final)

Green, purple: FPC-G, FPC-S Light blue : SCI SAFARI is omitted, just for better seeing for other FPIs

FPC optics can be delivered soon Orientation of SCI is not the current version

Near future updates, deliverables

SCI optics will be included in the CAD file, and its orientation will be corrected in the next round

FPC optics (under updates, new version will be available on 26th Apr.) will also be included in the CAD file

IOB mechanical design – to be discussed on 21st Apr. at JAXA Looking for a solution to satisfy the serious stiffness

requirements – need of a drastic idea? New SAFARI optics/envelopes will be included when

available.. Envelopes MIRMES, MIRHES will be deliverable in early

May (tbd) but no mechanical interference is expected with SAFARI
