The HTSC group has an access to a set of technological equipment for thin film preparation and laboratory measurement system for low temperature electrical measurements. The technological complex of the " Thin Film Oxide Electronics " Laboratory includes two clean rooms of the "1000" class, with a complete set of equipment for photolithography (spinner, oven, hot plate, mask aligner, chemical bench, de-ionized water source) in each clean room. ...

... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...

ENERGOSPECTROMETER OF IONOSPHERIC PLASMA P3-3 . ... 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. ...

... Calibration and sensitivity measurements for tests of microwave radiometers. ... The instrument consists of two waveguide matched loads operating at ambient temperature and two matched loads, cooled at variable temperatures. The temperatures are microprocessor-controlled. The test version of instrument is available. ... Dimensions                                          450 350 550 mm . ... Output temperature                                            100–350 й . ...

Note: These models for T-receiver are based on measurements for all of the 14 pipelines. download Trx polynomial fit parameters . ... any additional offset to be addded as a correction not incorporated in the model (e.g. the contribution to receiver temperature from beyond the pre-amplifier stages), . ... No. of coefficient pairs, n_harm, associated with the harmonic (Cos & Sin) part of the fit (where the final fit is a simple sum of the two parts).. ... cos(j*pi*X/2) & sin(j*pi*X/2), . ...

... A full set of flatfield frames was taken with the NICMOS arrays during the System Level Thermal Vacuum test, conducted on the ground in August 1996. ... Users are encouraged to recalibrate their data with on-orbit flatfields if the pipeline calibration used thermal vacuum flatfields. Preliminary results from SMOV indicate that variations in the large scale structure of the on-orbit flatfields relative to the thermal vacuum flatfields are of the order of 1-2% in Camera 2, and up to 5% in Camera 1. ...

... Theoretical and experimental investigations electrodynamical characteristics of RATAN-600. Calculation of the two- and thee-mirror periscopic systems of RATAN-600 and optimization their characteristics. Measurements and calculation of the antenna noise temperature of the RATAN-600 radio telescope. ... Calculation and experimental investigation of the characteristics of the radio telescope RATAN-600 when the primary feed is shifted from the focus. ... The "radio-Schmidt telescope" mode. ...

Next: Antenna gain considerations and Up: Some theory Previous: Some theory . To provide correct flux density units for the visibilities, , from an interferometer, the measured correlation coefficient at the correlator ( ) needs to be scaled by a system temperature and a telescope sensitivity factor ( ). ... For a zenith opacity , observing at an elevation of , and if the atmosphere is approximated as having a uniform temperature , then the atmospheric contribution to system temperature is . ...

... A. M. Neminsky, P. N. Nikolaev, and D. V. Shovkun . ... The temperature dependence of the magnetic field penetration depth lambda ( T ) is determined down to 0.2 T c by the ac-susceptibility measurements on the Rb 3 C 60 fine powder with small, about 1 K, variation in the grains' superconducting transition temperatures. The lambda ( T ) temperature dependence is exponential at low temperatures, which allows us to determine the energy gap Delta 0 =1.7 k B T c . ...

A study of Martian surface characteristics using microwave remote sensing technique at S-L-P bands (6-100 cm wavelengths) is suggested. The method is based on measurements of radar backscattering and brightness temperature variations induced by subsurface temperature, moisture, porosity and surface roughness changes. ... Combine active-passive microwave long-time observations are conducted along the route of the "Martian Orbital Station" . ...
