  1. Private conversation with company: the thermal conductivity given in the data sheet is only to be considered at pressures that we cannot reach with our setup. Furthermore, the vertical thermal coupling is potentially compromised by the non-perfect interfaces
  2. aSofttherm pad 86/600, Kerafol, data sheet: 6 W/(m K)
