Kompakti automatisoitu laser-ionisointijärjestelmä
In an experimental nuclear physics off-line systems are often used in situations where acceleration energies are relatively small. Main benefits are low price and meager radiated laboratory enviroments. In this master’s thesis I discuss mostly about automation which was used in our off-line system. The system was built at the Ion Guide Separator On-Line facility (IGISOL) in Jyväskylä University. The automation set up was made with the Phoenix Contacts inline terminals, which were programmed by using the Labview program. The system consists of thermistor, skimmer handling, mirror handling, gasline parts per billion (ppb) mixing and quadrupole mass spectrometer measurement. There were major problems with the control unit of the quadrupole mass spectrometer, hence this project is truly unfinished. On the other hand, the system will be modified for various purposes, so the system was partly tested. Test results show that the system works with low mass-charge particles. I have included quite detailed descriptions about my programs, thus this thesis can be also used as a program manual. ...
