... 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 . ...

ATNF ATUC MEMORANDUM To: ATUC From: Bob Sault Date: 29 May 2004 Subject Millimetre systems on the ATCA Performance of the 12mm system The 12mm system is now well integrated into the ATCA system, with performance being very good. ... Operation of the 12mm system is now routine. The system temperature measures of the 12mm receivers are now calibrated, and will need to be recalibrated after the 3mm installation period. 1934- 638 has been shown to be "constant" over more than a year. ...

... As any interferometer, even those with spectrometers, measure the visibilities integrated over band passes of non-negligible widths, computes model visibilities on a grid of wavelengths. The results (visibilities, fluxes) are then integrated over wavelength, whereby special attention needs to be payed to the averaging corresponding to what the instrument actually does. ... The choice of grid is made in function calcmodel , for each spectrometer. Christian Hummel 2015-04-28 ...
