The HAWAII detector is an array of HgCdTe photodiodes whose junction capacity collects a charge proportional to the number of photons that they receive. ... The array detector is read by an electronic system based on the controller developed by the CCD Working Group of TNG, modified to speed up the read-out time, and on a fast 16 bit conversion board (2 Mb/s). ... The signal read on each pixels is buffered by electronics located on the same board that hosts the detector. ...

... The very demanding goal of 50 milliarcseconds root-mean-square (mas RMS) for the astrometric precision of the Sloan Digital Sky Survey implies that focus and collimation motions of the secondary must be very smooth. The Apache Point Observatory 3.5-m telescope secondary is a hot-gas-fusion borosilicate lightweight (25% of solid) mirror. ... Differential rotation provides tilt motions. ... Also, we made measurements with the indicators sensing the motion of the whiffletrees near actuators 1 and 2. ...

The major objective of the P3-3 experiment is complex investigation the main parameters of ionospheric plasma with high time and spatial resolution. ... Measured parameters: . ... The experiment produce regular data - measured with fixed time interval and «packet» data - measured once per specific time interval and producing blocks of TM-information. ... If all parameters will be measured once per second, the experiment will produce 10 MB per orbit. ...

Feed cabin Nr. ... Fig. ... This allows to realize the sensitivity at frequency ranges 4.8, 11.2 and 30.0 GHz of 5, 7 and 12 mK by double beam switching mode and by the integration time of the output filter 1s. Input waveguide paths were very long and had big losses. ... The focal line of the feed cabin Nr. ... Data Acquisition and Control System . The Data acquisition system of the feed cabin Nr 2 is based on the new measurement ER-DAS system (Embedded Radiometric Data Acquisition System). ...

... In the colophon, written for the book prior to starting work on the electronic proceedings, I mentioned that the reason for producing the book from a single gigantic LaTeX file was the hope that it would simplify the production of the electronic version. ... I renamed contributions to the first author's last name and first initial (or two initials in the case of hyphenated first names) followed by .html , the convention established for the previous electronic proceedings. ...

The JPDOC gives access to references to the papers, data files and links to the internet resources related to measurements and calculations of the optical constants in the wavelength interval from X-rays to the radio domain. ... The database also provides links to internet collections of optical data files and personal WWW pages with relevant software and includes some other useful information. ...

... Since completing his PhD David has worked in several temporary roles with the ATNF, including a three-month sojourn in Narrabri, on various aspects of system performance related to operation at mm wavelengths. ... Part of the current ATCA upgrade provides new antenna stations to support improved compact antenna configurations, ultimately using the new North Spur to provide N-S baselines. ... Three millimetre receiver packages are now installed on the Array in antennas 2, 3 and 4. ...

The LIDAR Instrument Information . The LIDAR was designed in a bistatic scheme with a separate transmitter and two receiver channels. ... The total mass of the instrument is only 940 grams (about 2 pounds) and a total volume is 950 cubic centimeters in both assemblies. ... Engineers designed the LIDAR to operate in the temperature range from -100 to 50 degrees Celsius (-148 to 122 degrees Fahrenheit) under lower pressure, near one millibar. ... One of the receiver channels has polarizer. ...
