From an ion's perspective
Title of the project: Ion-Laser InterAction Mass Spectrometry of Cesium Isotopes
Name of the VDSP student(s) & image credits: Alexander Wieser
Project supervised by: Robin Golser (Univ. of Vienna) & Anton Wallner (TU Dresden)
About me/us: My name is Alexander and I am a Phd student at the University of Vienna as well as at the TU Dresden. At the moment I am working in Dresden but I always enjoy coming back to Vienna. My main job here is assembling and testing a new ion cooler for accelerator mass spectrometry, which is also where this photo was taken.
Image: Here we see the inside of a high-frequency quadrupole for negative ions. The ions fly through the quadrupole and are overlapped with a laser beam. Ions with the same mass but from different elements react differently to the laser light and can therefore be separated. When I was trying to find a leak in our quadrupole, I looked through it to see if I could see anything strange and realized that the quadrupole actually looks pretty cool from the inside.
