Introduction Basic Lunar Environment Simulator System is designed for pumping out using a single turbo pump, has one door for servicing and installing and replacing samples and a platform for fixing samples, heating and cooling them. This design allows you to increase the size of the vacuum chamber, install a second door on it, additional testing equipment and an additional turbopump. The system is designed to use a standard lunar soil/lunar dust simulant.
The design consists of a vacuum chamber that is pumped out by two vacuum pumps (one turbo pump and one scroll pump). Inside the vacuum chamber are:Filtration system that protects the pumps from dust ingress;

Design of Lunar Dust Filtering System
The filtering system of the pumped-out atmosphere from dust is an extremely important component of any simulator of the lunar environment. The filters used should not severely cut the pumping speed and be able to work for a long time without replacement. Filters should be easily removable and have a reliable dustproof seal. Four 5-micron Polyester elements are included. The holder of these four filters is tightly welded to the vacuum chamber.
Design of Dust Source
The dust source consists of two units: a dust preparation unit and the dust sprinkling mechanism. The main essence of this difference lies in the absence of a separate chamber for preparing the dust for work. This was achieved using a special cellular dust cleaning system. These technical problems should primarily include the following:An independent dust cleaning system requires the creation of devices for delivering dust to the source. In this case, a large number of mechanical components are required, which work extremely poorly in a dust atmosphere and require complex protection from dust ingress.
Design of Lunar Dust Filtering System
The application of a gate valve between two chambers (dust preparation and testing chambers) sharply reduces the service life. This is due to the ingress of dust particles on the working surface of the gate valve and, as a result, its rapid failure.
Difficulty in determining the amount of dust entering the dust sprinkling mechanism, and as a result, overloading or under loading of its hopper.
The need for an independent pumping system for the dust preparation chamber. This system must also have a sophisticated filter system to prevent dust from entering the pumps. Shows the appearance and section of cellular dust cleaning system.
Cellular dust cleaning system
Dust sprinkling mechanism is designed so that dust does not spill into the chamber when this mechanism switched off. Then the upper door is closed and the chamber is pumped out to a pressure of ~10-5Torr. When this pressure is reached, the cellular dust cleaning system is heated up at a temperature of 2000℃ for several hours. The criterion for the completion of dust cleaning is the pressure stability in the vacuum chamber (not worse than 10-5Torr) when the cellular dust cleaning system is heated to +2000℃. After successful preparation of the dust and the cellular dust cleaning system driven by a stepper motor starts to spill the dust on the top diffuser of the two-mesh system. When the cellular dust cleaning system is operated, the top layer of the mesh becomes covered with a uniform layer of dust, which is created due to a special design of an internal slotted plate.
