Buffer gas loading and subsequent magnetic trapping of neutral molecules is a powerful tool for the creation of dense samples of ultracold molecules and is applicable to a wide variety of paramagnetic species. Such dense samples of ultracold molecules can form a starting point for experiments aimed at studying the formation of a molecular quantum gas, to perform ultra-high resolution spectroscopic measurements, and to test fundamental physics or interactions between ultracold molecules.
In this project we aim to create dense samples of neutral paramagnetic molecules by means of buffer-gas loading and trapping inside a superconducting quadrupole magnet using a 3He-4He dilution refrigerator. We report on the progress and test of the experiment using atomic Chromium. We also discuss the perspectives for cooling and trapping OH and NH radicals and present results from related precursor experiments.
