Observatory report: Keck Cosmic Web Imager

l KCWI shipment was successfull It is in the telescope beam undergoing fine

alignmentl There are no significant technical problemsl All Level 1 requirements were metl Grating BH1 is delayed at the vendor due to the

complication of fabricating itl Grating BH3 suffers from low throughput, and it will

be remade at no cost after BH1 is complete

l First light on sky planned for April 11, 2017.

Keck Cosmic Reionization Mapperl Key engineering staff from KCWI-B team no longer

available – new team is being assembledl Will apply lessons learned from KCWI-Bl Engineering resources from WMKO, UCSC

(mechanical), JHU (opto-mechanical), Carnegie (project management, machine & electronics shops)

l Instrument lead: Matuszewski (Caltech)l Integration & testing to be done at Caltechl Currently selecting detector, specifying camera

5YearPlan• MajorGoals:

– Improveprojectperformanceandobservingsupport– Near-term,at-riskinfrastructureimprovements– Maintainourcurrentoperationsservicelevel

• KeyElements– RealisticNSFproposalassumptions– Keyinfrastructurerepairprojects
