For ATMO-SOS project the ESC-Q-UAIC reactor chamber facilities, from CERNESIM Centre (https://cernesim.uaic.ro/index.php/language/en/) will be involved:

The ESC-Q-UAIC chamber is a closed cylindrical vessel of internal dimensions of 0.48 m diameter and 4.2 m length. The reactor volume is of 760 L and the ratio of interior surface to volume is about 8.8 m^-1. This rigid reactor is made of three quartz tubes connected by flanges and is vacuum compatible. It can be operated over a range of pressure from 10^-3 to 1200 mbar. The chamber body is mounted on a steel framework with help of six adjustable anti-vibrating stands in order to limit the vibration effects coming from the ground level and the pumping system. The chamber is connected to the ground to prevent any electrical charge build-up. It is closed at both ends by stainless steel flanges with appropriate insertions for reactants and bath gases inlet systems, pressure and temperature measurement units. Sampling lines made either of PTFE or stainless steel are appropriately disposed for on-line/off-line measurements of various chemical parameters (gaseous or aerosol phase products). A schematic view of the existing ESC-Q-UAIC facility chamber is presented in the below scheme.

The ESC-Q-UAIC chamber is equipped with a large panel of analytical instruments dedicated to gas and particulate measurements as well as instruments for monitoring the physical parameters of the chamber (see the below scheme). However, a number of available ports provide space for the connection of other instruments which can be temporarily required to address specific scientific issues. Off and on-line analyses can be achieved by using the wide range of conventional analytical equipments.
