An aerosol generator for an electronic aerosol provision system includes an electrical heater formed from a ceramic body, an aerosol-generating material transfer component also known as a wick for delivering aerosol-generating material from a storage area to the electrical heater for heating to generate aerosol, and a thermocouple embedded in the ceramic material and operable to provide a temperature-dependent voltage via the thermoelectric effect from which a temperature of the electrical heater can be determined. The wick may be a bundle of fibers or wadding in contact with the ceramic body. Alternatively, the wick may be formed from a porous ceramic. The porous ceramic either is bonded to a non-porous ceramic configured as the heater body, or is used for both wicking and heating so that both wick and heater are formed from a single portion of ceramic material.

Some implementations described herein provide techniques and apparatuses for determining a performance of a dry-clean operation within a deposition tool. A cleaning-control subsystem of the deposition tool may include a gas concentration sensor and a temperature sensor mounted in an exhaust system of the deposition tool to monitor the dry-clean operation. The gas concentration sensor may provide data related to a concentration of a chemical compound in a cleaning gas, where the chemical compound is a bi-product of the dry-clean operation. The temperature sensor may provide temperature data related to an exothermic reaction of the dry-clean operation. Such data may be used to determine an efficiency and/or an effectiveness of the dry-clean operation within the deposition tool.

A ducting system has a first upstream location is to be connected to a first source of air. A downstream location in the duct is to be connected to a second source of air. The upstream location has a first valve, and the downstream location has a second valve. An end location of the duct is to be connected to a sink. A control for the valves achieves a desired pressure and temperature of air at the end location. The first temperature sensor is located at a position intermediate the upstream location and the downstream location. A second temperature sensor is located at a position intermediate the downstream location and the end location. A control is programmed to determine the health of the first and second valves based upon a difference between temperatures sensed by the first and second sensors. An air use system and a method are also disclosed.
