AAO is completing
the build phase of its
work on the GHOST
Cassegrain unit,
including its integral
field unit (IFU).

subassembly enclosure

frame (black) attached
to the Instrument
Support Structure (ISS)
mounting plate (silver).
Right: A detailed
image of the IFUs and
positioning arms.
The team will test over the next two to three
months to verify that requirements are met
prior to shipping the slit viewer and science
optical cable to Canada for integration with
the spectrograph, which the NRC-H is build-
ing. The Cassegrain unit will also be tested
prior to shipping with the prototype optical
cable to Chile for preliminary testing on the
telescope. All of this work is to ensure that
everything is working in preparation for the
arrival of the spectrograph later in 2018.
To date, the build team has submitted 74
design requirements verification reports to
Gemini, all of which were accepted.
