Fig. 1From: Design of a Mars atmosphere simulation chamber and testing a Raman Laser Spectrometer (RLS) under conditions pertinent to Mars rover missionsSketch of the Mars atmosphere simulation chamber (MASC) a Lauda cooling machine, b heat exchanger type HE, c pump used to circulate Freon, d the two main doors with small flanges for electrical-thermal, optical feed-throughs, e mounting plates, f cooling screen, g RLS spectrometer, h optical head. There are several temperature sensors: sensor (1) is on the cooling plate, sensor (2) is on the sample tray and sensor (3) is on the left main doorBack to article page
