This invention discloses a compact high-temperature, high-pressure transmission XAFS in-situ cell, comprising a cell body and a cover that are sealed together. A light-transmitting window assembly is installed on the cell body, allowing X-rays to pass through and irradiate the sample to be tested, which is installed inside the cell body. The cell body and cover are also connected to and equipped with components such as a ball valve, a gas connection, a temperature probe, test electrodes, and a heating element. The heating element is used to regulate the sample temperature, and a water-cooling structure located in the side wall of the cell body is used to regulate the cell body temperature. This invention integrates a ball valve control structure on the same cell body. When the ball valve is closed, a high-pressure atmosphere can be established and maintained inside the cell body to achieve high-temperature, high-pressure transmission XAFS experiments; when the ball valve remains open, the inside of the cell body is in a normal-pressure gas flow state, achieving high-temperature, normal-pressure transmission XAFS experiments. One device can meet the testing requirements of two different operating conditions, significantly reducing the user's equipment investment costs.
