Technical scheme of the IGLIAS chamber adapted from Augé et al. (2019). Experimental windows are disposed on a rotary head at the center of the chamber and in contact with a helium cryostat cooling system and a heating system. Ice samples are formed by the condensation of gas injected on the cooled windows. The chamber is connected to the IRRSUD ion beam at GANIL. The evolution of the IF during irradiation is monitored by a Fourier transform infrared spectrometer (FTIR) with a 12° incidence angle. A quadrupolar mass spectrometer (QMS) is connected to the chamber to monitor the gas phase.
