The laboratory power supplies (external, on the left) were for testing only.
MONSOON System Delivered to KPNO
A complete MONSOON CCD controller was delivered to the Kitt Peak National Observatory engineering staff this month. This system consists of the Master Control Board, Clock & Bias Board, CCD Acquisition Board, backplane and chassis, associated transition boards. The KPNO staff will use this system for training and familiarity, with a goal of integrating it into the WIYN Bench Spectrograph as part of a detector upgrade for that instrument.
MONSOON System Delivered to NEWFIRM Project
A complete MONSOON system for controlling the very large NEWFIRM focal plane was handed over to the NEWFIRM project this month. NEWFIRM (the NOAO Extremely Wide Field IR Imager) has a focal plane mosaic made up of four ORION arrays from Raytheon Vision Systems. Each ORION array provides 64 video channels of output for rapid readout of its 2048x2048 InSb pixels; the entire focal plane thus requires 256 video channels of connection with the MONSOON controller. The MONSOON system for NEWFIRM consists of two separate Pixel Acquisition Nodes (PANs), with each PAN made up of a backplane, a Master Control Board, a Clock & Bias Board, and four IR Acquisition Boards, along with all the associated transition boards. There is also a Supervisor program “above” the PANs which provides the essential coordination and image assembly for the unified focal plane.

Interim MONSOON System Delivered to WHIRC Project
This month an interim MONSOON IR controller was delivered to the WHIRC project team. WHIRC is an IR science camera to go on the Tip-Tilt Module for the WIYN telescope. Its focal plane consists of a single Rockwell 2048x2048 pixel array made up of HgCdTe diodes. This is considered an interim shipment because it includes an older version of the IR Acquisition Board that will be replaced when a Board in the latest revision is available. The other boards – Master Control, and Clock & Bias – are the latest versions. This interim system is being supplied now to help the WHIRC team become familiar with the MONSOON controller and experiment with its use on their engineering grade detector.
MONSOON System Installed on NOAO IR Detector Test Dewar
A MONSOON IR controller was delivered to the NOAO IR Detector Test lab this month. This controller will be used for testing of ORION arrays developed by Raytheon Vision Systems under the foundry run agreement to build detectors for the NEWFIRM instrument. This controller consists of the Master Control Board, the Clock & Bias Board, and two IR Acquisition Boards to support the 64 channels of video output on the ORION controller. It also includes the Linux-based computer for running the Pixel Acquisition Node (PAN) software. Early tests on arrays previously tested with other controllers demonstrate that this MONSOON system is providing detector-noise-limited performance, while supporting the high channel count needed to read the entire ORION array simultaneously.

November 14th, 2004 MONSOON Open Source Licensing Approved and in Effect AURA and NOAO are proud to announce the release of the MONSOON technology under the umbrella of 'Open Source Licensing'. This has been a long sought after decision that we feel will allow the technology to advance in the common interests of, and be more readily adopted by, observatories requiring a Detector Image Acquisition System to meet future focal plane requirements. We invite you to become a 'Friends of MONSOON' community member and urge you to investigate the possibilities that MONSOON technology will provide for you. This accomplishment has been possible thanks to the hard work put in by NOAO Directorship, Major Instrumentation leadership and the MONSOON development group The MONSOON Development Program is funded by the National Optical Astronomy Observatory (“NOAO”), which is operated for the National Science Foundation (“NSF”) by the Association of Universities for Research in Astronomy (“AURA”) under Cooperative Agreement No. AST-0132798.

Orion II bare MUX read out with the MONSOON Image Acquisition System

Note: The detector reference columns can be seen in this image as well as 5 bad row-pairs.
To see a higher resolution image, please click here
MONSOON has read out an Orion II bare MUX in preparation for connecting the camera to a fully functional detector. The Orion II detector is a hybridized 2048 x 2048 InSb NIR detector with sensitivity out to 5um and 64 output channels. The tests conducted with the MONSOON Image Acqusition system are part of a lead up to the development of a 2 x 2 mosaic of these detectors to be employed by the NEWFIRM instrument. MONSOON will be used to characterize further ORION II developments and be the image acquisition system for NEWFIRM. This image was captured and readout in under 1/2 second with a system noise level below 10 e- rms. The current performance tests were performed with a warm mux while imaging an original orientation setup mask: RIO is now known as RVS.

Monsoon runs CCDs

News from CTIO
The mux was at ambient temperature, and in continuous reset when idle. A single image was taken, with the integration time set to zero. The effective integration time was app 3.4 seconds (the readout time). The readout is made from four channels, just like the ISPI detector. Reading from 32 channels (which is an option available for this device) requires designing a new board, which was out of the scope for this test.
