THe-Trap is a Penning trap mass spectrometer, specifically constructed to measure the mass ratio of tritium (3H) and a light helium isotope (3He) with a relative uncertainty of 10−11 or below. It was originally designed and built at the University of Washington, Seattle, and was moved to the MPIK in Heidelberg in 2008. Following modifications and improvements to the experimental setup as well as its environment, several mass measurements of light ion species have been conducted in its commissioning phase. Measuring the well known mass-ratios of different ion species gives a first estimate of the achievable accuracy and precision of our spectrometer.
Our first mass measurements will be presented and current limitations, as well as future upgrades, will be discussed.
