Temperature distribution in the diamond anvil pressure cell at high temperature

Abstract
The temperature distribution in a diamond anvil pressure cell is investigated theoretically for a model cell having a cylindrical external heater. For a heater surface at 1000 absolute degrees above the ambient temperature, it is found, at steady state, that the region of the sample chamber is, for all practical purposes, isothermal at a temperature of about 11 degrees below the temperature of the heater. When the heater temperature is subsequently incremented instantaneously by 10 degrees, a new steady state is reached in about 30 sec.
