• GLAO observing

• F/5 instrument cart delivered

SAO F/5 instrument cart

Instrument activities

• LDSS wheel encoders, cable wrap

• Iodine cell remote control

• MagIC upgrade tests

• IMACS cooler repair

• IMACS CCD repair

Instrument activities

Computer networking

• Network administration was a 10% effort from

Magellan programmer

• New instruments require more support

• LCO arranged for CTIO management– More IP addresses– Adds routers and firewall– Connects to CTIO network

Clean room for large IR instruments

• MMIRS and FourStar are large (3x3x10 feet)

• Detectors need protection from static

electricity and particulate contamination

• Detectors are expensive ($2.5M for FourStar)

• Undisturbed workspace needed for long

periods for assembly and repairs

Clean room for large IR instruments

• Clean room is required to support large

infrared instruments

• Proposal development in progress

Carnegie shop

• New purchases– CNC lathe– CNC mill

• Increases production throughput

Instruments

• Assume we can support six facility

instruments

• How to handle incoming 7+ instruments

• Plus new telescope subsystems (new

secondaries, AO, etc.)

Instruments

• Instruments can displace similar equipment

(trade PANIC for FourStar)

• User status (PI or other expert required on

every observing run)

• Mothball (minimum 18 months) to

accommodate the new

• Decommission
