We have investigated spin accumulation in Ni/Au/Ni single-electron transistors assembled by atomic force microscopy. The fabrication technique is unique in that unconventional hybrid devices can be realized with unprecedented control, including real-time tunable tunnel resistances. A grid of Au disks, 30 nm in diameter and 30 nm thick, is prepared on a SiO2… (More)
Computer control of time delay of the extraction of ions from the ion source of the TOF mass spectrometer is presented. Owing to the computer, the user has the full control of power parameters and ion current delay, which is about microseconds.
The computer program controlling MALDI system and a time of flight mass spectrometer is described. This program allows to reduce a number of necessary activities for operation of used machines as well as to raise an operational safety of this equipment. Additionally, an advantage of the computer control is possibility of quick changing of any measurement… (More)
