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…
