Abstract
A method of manufacturing an aerosol provision apparatus for heating smokable material to volatilize at least one component of the smokable material, and an aerosol provision apparatus, are described. The method includes providing a heater arrangement for heating smokable material contained in use within the apparatus, the heater arrangement including at least a first heating zone and a second heating zone for heating different portions of the smokable material, providing a temperature sensor for each of the first and second heating zones, each temperature sensor for providing temperature measurements to be used as input temperature measurements for a temperature control loop, the control loop for controlling the heater arrangement to heat its associated respective heating zone to a target temperature based on the input temperature measurements acquired by the associated temperature sensor, and positioning each temperature sensor in its associated heating zone at a respective position selected so that if the heating arrangement were to heat the first and second heating zones so that the temperature sensors measure the same pre-selected target temperature, a temperature gradient acr…
