WORKING WITH CANARYCANARY is an open-loop Adaptive Optics system which will use multiple laser guide stars and deformable mirrors and will provide the first on-sky test of combined wide-field LGS tomography and open-loop AO control. On-sky validation of these combined techniques will be performed with the goal of emulating a single channel of the proposed E-ELT MOAO instrument, EAGLE, albeit at 1/10th scale.
StartupThere are no cryostats to fill!
It's safe to start with the nominal focus, and then make adjustments if the CANARY team request them.
Rotator centre and Calibrate Procedure:
AutoguidingThe Autoguider to TCS selection switch should be in position CANARY (position no.5). When autoguiding is used the CANARY system will send autoguiding packets to the TCS. This should be visible on the encoders page. There is no need to find a guide star as it is self-guided. To start guiding:
Data HandlingThe CANARY team will handle their own data.
TroubleshootingGHRIL Optical Derotator:
If the GHRIL derotator fails to move under computing and engineering control its power supply may have been tripped. This is located in the blue nasmyth rack in the WHT control room. Near the bottom there are two units, a Power Distribution Unit and a Power Supply Unit. The Power Supply Unit is the power source for the GHRIL derotator. If the lights on this unit are off the power to it has tripped. Check that the mains breaker on the Power Distribution Unit above is on and the mains light is lit. If not, switch to engineering mode and reset the breaker. The derotator should then be able to move.
