We compare the vacuum measured by two portable cold-atom vacuum standards (pCAVS) based on ultracold $^7$Li atoms. The pCAVS are quantum-based standards that use a priori scattering calculations to convert a measured loss rate of cold atoms from a co

Here, we study the stability of capacitance diaphragm gauges. We focus on their stability before and after a controlled series of bakes. We find that baking results in appreciable shifts of the zero offset, but note that these can easily be corrected
