Kicking Away the Ladder: Neoliberalism and the ‘Real’ History of Capitalism

Abstract

A new improved method of calibrating waveguide power standards is described. The main improvements are that the measurement time has been reduced from two hours to 15 minutes and a residual error has been eliminated. This has been achieved while maintaining a mechanically flexible design. The theory for using the isothermal process is developed and it is shown that all linear (i.e. conductive) imperfections of the microcalorimeter are corrected for, together with any effects due to incomplete settling of the exponential time constants. The uncertainty budget is presented giving a total uncertainty of +or-0.5% (1 sigma ). The isothermal method is compared with the conventional method at 75, 80, 85 and 94 GHz and is shown to agree to within the overall uncertainty.
