Abstract: PURPOSE: A cold trap for removing contaminants during operation of vacuum pump of thermal vacuum chamber that is used to simulate cosmic environment on ground is provided to adsorb contaminants easily while saving consumption of LN2. The adsorbed oil vapor and water vapor are easily removed. The vacuum pump operates only when the temperature of the cold trap set between the vacuum pump and thermal vacuum chamber drop down to 150 deg.C below zero so that oil vapor attaches to the inside of interior vessel thus preventing any back flow to vacuum chamber. CONSTITUTION: The cold trap comprises an exterior vessel(1) and an interior vessel(2) of vertical cylinder type. The interior vessel(2) with bottom closed and a cover(8) fixed to the top edge is set inside the exterior vessel(1) with the edges of both vessels tightly sealed by O-ring(6) and clip(7), at the cover an LN2 inlet with a solenoid valve(10) and a gas discharge line(11) fixed and a temperature sensor(12) being inserted. The exterior vessel(1) set around the interior vessel(2) has a vacuum pump(3) connected to the side middle, a chamber(13) connected to the side middle at the other side and a drain valve(5) at the bottom.
