Scientific paper

An NOAO MONSOON CCD controller will be used with the Fiber High Resolution Echelle Spectrograph (FHiRE) under construction at Indiana University. In preparation for integration of the FHiRE CCD system, work on the MONSOON controller was initiated. MONSOON clocking signals and bias voltages were checked electronically to confirm they were produced as expected against standard configuration files delivered with the MONSOON software. Diagnosis revealed the need to replace one operational amplifier. Once the amplifier was replaced on the clock and bias board, the controller produced the expected signals within specification. The MONSOON image acquisition software was then tested with a simulated SITe detector head and the test images were evaluated. From the test data, we were able to correlate input from the simulated CCD with specific quadrants in the image. The default configuration files from NOAO were modified for the SITe CCD to be tested.
MONSOON schematics and technical documentation were reviewed for the design of wiring diagrams to connect the MONSOON detector head electronics to a SITe 1024 x 1024 CCD for testing purposes. The design is now complete and the connector will be wired to allow us to test an actual SITe CCD for image acquisition.
