During its cold mission phase at 7 K the Mid Infrared Instrument (MIRI) is the coldest spot on the James Webb Space telescope (JWST) and will act consequently as a cryopump of the instrument's environment. Since the absorption of outgassing molecules from the spacecraft (mainly water and hydrocarbons) on optical surfaces would lead to a significant degradation of the optical performance of MIRI, a Contamination control Cover (CCC) has been introduced. This coer is placed in the entrance optical path of MIRI's right after the pickoff mirror (POM) and will be closed during the instrument's cool down phase and at MIRI'S operational temperature each time the POM is heated up for decontamination. The CCC will be used further as an optical shutter for dark sky calibration and for the protection against latency images which might emerge from coronographic filter changes. Therefore, the CCC has been designed to be multi operational with approximately 3000 life cycles. A contact-free labyrinth seal allows the required reduction of molecular flow towards the instrument and avoids the possibility of any freezing. The CCC is operational between 300K and 7K and is actuated by two redundant stepper motors. In this paper we describe the design of the CCC and the results of the qualification campaign. Further a dedicated measurement of its molecular conductance at various temperatures is presented.

The Multiple Mirror telescope (MMT), upgraded in 2000 to a monolithic 6.5m primary mirror from its original array of six 1.8m primary mirrors, was commissioned with axis controllers designed early in the upgrade process without regard to structural resonances or the possibility of the need for digital filtering of the control axis signal path. Post-commissioning performance issues led us to investigate replacement of the original control system with a more modem digital controller with full control over the system filters and gain paths. This work, from system identification through controller design iteration by simulation, and pre-deployment hardware-in-the-loop testing, was performed using latest-generation tools with Matlab (R) and Simulink (R). Using Simulink's Real Time Workshop toolbox to automatically generate C source code for the controller from the Simulink diagram and a custom target build script, we were able to deploy the new controller into our existing software infrastructure running Wind River's VxWorks (TM) real-time operating system. This paper describes the process of the controller design, including system identification data collection, with discussion of implementation of non-linear control modes and disturbance decoupling, which became necessary to obtain acceptable wind buffeting rejection.

An inexpensive solution using an artificial vision system appears to the problem of pointing, tracking and guiding a telescope. A stellar sensor called "R2D2" has been developed. The elements of the system are a CMOS sensor with the respective optics and "Oeil 1.0", a software package that we have developed under the object oriented environment of Matlab 7.0. The software is built in a graphical user interface that allows an easy interaction between the user and the system. The stellar sensor is mounted in parallel to the telescope, captures images of the night sky and sends them to the software, which makes preprocessing and noise reduction routines, identifies the stars and their centroids, and calculates the equatorial coordinates of all the stars, the center of the image and any other point into the image. Finally the tracking of the stellar object placed in the center of the field of view is made thanks to the continuously feedback of images and the successful results obtained with the image processing techniques.

LINC-NIRVANA (LN) is a German-Italian Fizeau (imaging) interferometer for the Large Binocular telescope (LBT). The Instrument control software (ICS) of this instrument is a hierarchical, distributed software package, which runs on several computers. In this paper we present the bottom layer of the hierarchy - the Basic Device Application (BASDA) layer. This layer simplifies the development of the ICS through a general driver architecture, which supports different types of hardware. This generic device architecture provides a high level interface to encapsulate the hardware dependent driver. The benefit of such a device architecture is to keep the basic device-driver layer flexible and independent from the hardware, and to keep the hardware transparent to the ICS. Additionally, the basic device-driver layer supports interfaces to IDL based applications for calibration and laboratory testing of astronomical instruments, and interfaces to engineering GUIs that allow to maintain the software components easily.

The GTC azimuth and elevation axes control systems employ large custom direct-drive motors operated by means of embedded fully-digital current loops. A high-performance position loop has been developed based on sinusoidal encoder feedback with interpolation error compensation. Real-time servo feedback and trajectory tracking is implemented by object-oriented software components at CPU-level which trigger encoder sampling, interpolate the remote CORBA demands and perform high-frequency setpoint streaming for the servo controller.

The VLT Survey telescope (VST), a telescope with a 2.6 m. primary mirror designed and implemented by I.N.A.F. in cooperation with the European Southern Observatory (ESO), is provided with an active optics system to correct the optical aberrations due to polishing imperfections, misalignments, thermal and gravity reasons. For the primary mirror, a distributed control system is required to impose the desired force values in a sufficient number of points to maintain the optimal shape in different positions of the altitude axis. The forces are applied by means of 84 electro-mechanical actuators, provided with an electronic Primary Mirror Actuator control Boards (M1ACB). This paper focuses mainly on the hardware electronics and is referred to the control system new version, designed in 2007, whose implementation is in progress. The new design has taken into account all the experience done on the system previous version, solving all the encountered problems of functionality and reliability.

The Cornell Caltech Atacama telescope (CCAT) is a 25 in diameter telescope that will operate at wavelengths as short as 200 microns. CCAT will have active surface control to correct for gravitational and thermal distortions in the reflector support structure. The accuracy and stability of the reflector panels Lire critical to meeting the 10 micron HWFE (half wave front error) for the whole system. A system analysis based upon a versatile generic panel design has been developed and applied to numerous possible panel configurations. The error analysis includes the manufacturing errors plus the distortions from gravity, wind and thermal environment. The system performance as a function of panel size and construction material is presented. A compound panel approach is also described in which the reflecting Surface is provided by tiles mounted oil thermally stable and stiff sub-frames, This approach separates the function of providing ail accurate reflecting Surface from the requirement for a stable structure that is attached to the reflector Support structure on three computer controlled actuators. The analysis indicates that there are several compound panel coil figurations that will easily meet the stringent CCAT requirements.

A typical high-resolution encoder interpolator relies on careful mechanical alignment of the encoder read-heads and tight electrical tolerances of the signal processing electronics to ensure linearity. As the interpolation factor increases, maintaining these tight mechanical and electrical tolerances becomes impractical. The Large Binocular telescope (LBT) is designed to utilize strip-type encoders on the main axes. Because of the very large scale of the telescope, the accumulative length of the azimuth and elevation encoder strips exceeds 80 meters, making optical tape prohibitively expensive. Consequently, the designers of the LBT incorporated the far less expensive Farrand controls Inductosyn (R) linear strip encoder to encode the positions of the main axes and the instrument rotators. Since the cycle pitch of these encoders is very large compared to that of optical strip encoders, the interpolation factor must also be large in order to achieve the 0.005 arcsecond encoder resolution as specified. The authors present a description of the innovative DSP-based hardware / software solution that adaptively characterizes and removes common systematic cycle-to-cycle encoder interpolation errors. These errors can be caused by mechanical misalignment, encoder manufacturing flaws, variations in electrical gain, signal offset or cross-coupling of the encoder signals. Simulation data are presented to illustrate the performance of the interpolation algorithm, and telemetry data are presented to demonstrate the actual performance of the LBT main-axis encoder system.

The derived heat loads from thermal models are used to size the equipment that controls exterior enclosure seeing for the advanced Technology Solar telescope. These loads are highly dependent on the radiative properties assumed for the surface coatings of the enclosure. The properties of traditional white coatings and paints are known to degrade with time as they are exposed to the elements, but not by how much or how quickly. The solar reflectance and thermal emissivity of coatings considered for use on the enclosure, in a weathered condition, are not readily available from coatings manufacturers or in the scientific literature. The results from a one-year test of nine different coatings that were weathered at the summit of Haleakala on the island of Maui, Hawaii are reported and discussed.

LINC-NIRVANA is an innovative imaging interferometer fed by dedicated multi-conjugated adaptive optics systems. The instrument combines the light of the two, 8.4-meter primary mirrors of the Large Binocular telescope (LBT) on a single focal plane, providing panoramic imagery with 23-meter spatial resolution. The instrument employs a number of innovative technologies, including multi-conjugated adaptive optics, state-of-the-art materials, low vibration mechanical coolers, active and passive control, and sophisticated software for data analysis. LINC-NIRVANA is entering its final integration phase, with the large adaptive-optics and imaging subsystems coming together in the clean room in Heidelberg. Here, we report on progress, including insights gained on integration of large instruments.
