A remote steering antenna designed as a symmetric direction antenna is prepared for electron cyclotron heating (ECH) and current drive (ECCD) experiments on the TRIAM-1M tokamak. the steering angles of 8-19 degrees are available in the design, in addition to the angle near 0 degrees. the antenna is tested at both of high and low power levels. the fraction of radiated power to injected power at the antenna is roughly evaluated at the low power test. the angle radiated from the antenna is checked from both of the intensity and phase measurements at the low power test. Several percentage losses at the antenna are evaluated at the high power test. the antenna system is evaluated to work correctly.

conference on current developments in Lens design and optical engineering IV

ISBN: (纸本)0819450464

the National Ignition Facility (NIF) requested an optical diagnostic for measuring shock velocities, shock breakout times, and shock emission of objects with sizes of I to 10 mm. For the polar port of the target chamber, an 8-inch triplet lens collects light at f/3 inside a 30-foot-diameter vacuum chamber and uses an optical relay to send the image into two interferometers located at a distance of 160 feet. Light propagates through a VISAR (Velocity Interferometry System for Any Reflector) interferometer employing a Mach-Zehnder configuration. After exiting the interferometers the images are recorded, both by streak cameras and CCD gated imagers. Discrete magnification changes are accomplished by swapping out optical elements. Large dove prisms are used to rotate the image to align a selected region of the object with the slits of the streak cameras. Unique mounting structures are required to remotely control the alignment of the optical axis. Finite Element Analysis (FEA) was performed on all mounting structures. the first 8-inch triplet can be no closer than 500 mm from the target chamber center and is protected by a blast window that has to be replaced after every event. the first several lens groups have to be fused silica for radiation resistance. A frequency-doubled Nd:YAG laser, operating at 659.5 nm, is used to illuminate the moving object. the VISAR laser wavelength had to be different than the first, second, and third harmonics of the NIF drive lasers.

the need for simulation models that are reliable and able to predict the conceptual as well as the implementation errors early in the design process is a must in the current tight time to market constrains. In this paper a model for a 1.25 Gb/s fiber channel transmitter is presented. the model is implemented using the IEEE 1076.1 standard VHDL-AMS. the modelled system is composed of two sections;an analog section, comprising the laser diode and the laser driver, and a digital section, consisting of an 8B/10B encoder and a 10:1 multiplexer.

conference on current developments in Lens design and optical engineering II

design variants of a recently developed optical imaging system have been computed for the thermal infrared spectral bands, which offer some advantages for long-range surveillance and astronomy. Only the spherical primary mirror has the fall pupil diameter, all other components being sub-diameter, so scaling is possible up to relatively large pupils. Low-cost fabrication is enabled by the prevalence of spherical optical surfaces. Both MWIR and LWIR spectral transmissions are enabled by the choice of corrector materials, the examples given employing germanium and sapphire for 3.5-5.5 mum and germanium and zinc selenide for 3.5-5.5[mum and 8-12mum passbands. Diffraction at these wavelengths is the main contributor to resolution constraints, so high numerical aperture values are preferred to enable a better match of blur spot diameter to generally available pixel dimensions. the systems described can routinely be designed to have speeds of f/0.8 or faster, while maintaining diffraction-limited performance over useful angular fields. Because the new design system employs a relayed catadioptric, it is possible to make the aperture stop of the system coincident with the window of the detector cryostat, enabling precise radiometric geometry. the central obscuration provides a convenient location for a calibration source, and both this and a mask for secondary spider supports can be included within the detector cold screen structure. Dual-band operation could be enabled by inclusion of a spectral beam splitter prior to a dual relay/imager system.

conference on current developments in Lens design and optical engineering II

there are some unique optical design considerations in the design of a distributed aperture telescope array consisting of a number of individual afocal collector telescopes and a single combining telescope. As might be expected, diffraction limited imagery over the field of view requires the correction of spherical aberration, coma, astigmatism and field curvature. However, there is an additional requirement on the design of the collectors. Coherent addition of the light from the collectors requires that the ratio of the sine of the input and output chief ray angles be essentially constant over the field of view. this output angle restriction is equivalent to requiring the collector telescopes to have a specific variation in angular magnification with field. Variation of magnification with field is, by definition, image distortion. With simple two and three mirror afocal collector telescope designs, there are insufficient design degrees of freedom to control distortion in addition to the other aberrations. In this paper, we present a modification to a three-mirror collector design that permits the image distortion to be adjusted in a controlled manner without influencing the other third order, Seidel aberrations. this modification permits a large distributed aperture telescope array to be designed that has both a simple optical form and a much larger phased (i.e. corrected) Field of view. As a design example, we investigate the effect of the distortion correcting element on the size of the achievable field of view for a 45 meter diameter distributed aperture telescope array populated with 8 meter diameter collectors.

the Chemical Imaging System (CIS) is a small, high-speed long-wave infrared (8 - 12 mum) imaging spectrometer which is currently under development by the United States Army. the fielded system will operate at 360 scans per second with a large format focal-plane-array. the CIS, which is currently at the exploratory development stage, is scheduled for transition to engineering development in 2005. currently, the CIS uses the TurboFT FTS in conjunction with a 16-pixel direct-wired HgCdTe detector array. the TurboFT spectrometer provides high-speed operation in a small, lightweight package. In parallel to the hardware developments an algorithm and software development effort is underway to address some unique features of the CIS. the TurboFT-based system requires a non-uniform sampling Fourier transform algorithm in order to preserve signal fidelity. Also, the availability of multiple pixels can be exploited in order to improve the interference suppression capabilities of the system by allowing the detection and identification algorithm to adapt its parameters to the changing background. Due to the enormous amount of data generated, the signal processing must proceed at very high rate. High-speed computers operating with a parallel architecture are required to process the data in real time. this paper describes the current CIS "bread box" system. It includes some field measurement results followed by a discussion of the issues and challenges associated with meeting the design goals set for the program.

the concurrent design of a product and its manufacturing process requires a shared understanding of products and processes among many experts concerned with design and manufacturing. the objective of this paper is to provide an approach for the representation, integration and communication of different experts' viewpoints in the design and manufacturing phases. Firstly, we describe the problems related to concurrent design and current research works. then we explain how, using the STEP standard, we can represent an integrated design and manufacturing model. As a case study, we consider the tracking of work-piece dimensions through all the different stages of product development, from design to machining. It is based on a model of machining tolerances based on a factory's machine-tool characterization. the chosen application case is a turning process. the model is validated by verification of the theoretical results in the case of machining several representative parts. Experiments point out the efficiency of our machining model. Finally, we present future developments of our integration work.
