Previous page: Measuring temperatures and composition in the ionoshere . If the actual spectra that the radar measures from the ionosphere consisted of continuous smooth curves, and if it was necessary to measure only two quantities, say the width and the total power, then one could use a ruler and get pretty good answers. ... There is no simple way to get from the data points to the best answers, but one would say that one spectrum is much better than the other. ...

... Equipment . ... At present our UHV equipment consists of two UHV STMs. The first one is a room-temperature STM GPI-300 (atomic resolution on metals) connected with a UHV technological chamber. The chamber is equipped with a sample heater, deposition equipment, tip-clean equipment and a low-temperature 4-probe conduction measurement unit. ... The temperature interval is 5-300 K, the vacuum in the STM chamber is usually better than 10 -10 Torr (typical value 3x10 -11 Torr). ...
