Step4:
Add thermal couples thermocouples to your chamber and keep them in place using small aluminum strips spot welded onto the chamber. Where to place the thermal couples is up to you, but placing them where you believe the hottest area will be is sufficient. Type K thermocouples, which are made up of two metals Chromel and Alumel, is what we typical use as temperature sensors.

Apply a thin layer of aluminum foil to the chamber and on top of thermal couplesthermocouples. Do not cover electronics or handles with aluminum and avoid areas that do not have high bakeout temperatures such as, turbos and roughing pumps. Applying a thin layer of aluminum helps spread the heat provided by the heater tape, since aluminum is a good conductor of heat. If the heater tape is applied directly to a steel chamber you can potentially have hot spots because steel is not a good conductor of heat.
