Nonevaporable getter MEMS for generating UHV conditions in small volumina authored by Leonard Frank Diekmann, Alexander Kassner, Folke Dencker, Marc Christopher Wurz Abstract The industrial use of quantum sensors requires further miniaturization of the experimental peripherals, i.e., the high vacuum chamber, laser technology, and control electronics.

Die Erzeugung und Aufrechterhaltung der Hochvakuumatmosphäre erfolgt dabei mit passiver, miniaturisierter und integrierter Vakuumpumptechnologie in Form von nicht verdampfbarer Getter (NEG) als mikro-elektro- mechanisches System (MEMS). Als gasbindende Vakuumpumpe sättigt das NEG mit zunehmender Betriebszeit durch die Bindung reaktiver Restgaskomponenten aus der Vakuumatmosphäre.

A beam of chromium atoms is generated by a high temperature effusion cell and decelerated by a Zeeman slower before being loaded into a magneto optical trap MOT , whereas the rubidium MOT is loaded from thermal atoms out of a resistively heated getter source. The bosonic isotope 52 Cr which is easier to cool is used to test the new approach. External Organisation s University of Stuttgart Type Conference contribution No. of pages 1 Pu...

In this Master s thesis, a prototype of a miniaturised ultra high vacuum UHV pump in the form of a non evaporable getter NEG pump on wafer level MEMS for maintaining UHV conditions for small quantum sensors is developed. The work was made possible by funding from QuantumFrontiers Flexible Funds programme.

In our scheme, the ions are buffer gas cooled and held in a linear quadrupole trap that is integrated into a sealed, getter pumped vacuum package, and interrogated on the 12.6 GHz hyperfine transition. We hope to achieve a long term fractional frequency stability of 10 14 with a complete miniature clock.
