A centimeter-sized gas pressure sensor for high-vacuum measurements at cryogenic temperatures
Christoph Reinhardt, Lea Lara Stankewitz, Daniel Hartwig +5
Gas pressure sensors based on nanomechanical membranes have recently demonstrated an ultra-wide ten-decade measurement range, a gas-type-independent response, and a self-calibratin…

Measurement of the thermal accommodation coefficient of helium on a crystalline silicon surface at low-temperatures
Alexander Franke, Nils Sültmann, Christoph Reinhardt +5
Next-generation gravitational wave observatories are expected to use cryogenically cooled, pendulum-suspended 200 kg test mass mirrors from a crystalline material such as crystalli…

Self-calibrating gas pressure sensor with a 10-decade measurement range
Christoph Reinhardt, Hossein Masalehdan, Sandy Croatto +6
Recent years have seen a rapid reduction in the intrinsic loss of nanomechanical resonators (i.e., chip-scale mechanical oscillators). As a result, these devices become increasingl…
