|Description of the infrastructure|
|Brief general description of the infrastructure to which access is offered||
ISAC is a medium sized indoor simulation chamber which has been developed specifically to investigate interfaces processes such as air-water-air, air-sol,…, interfaces. It is made of a 2m3 Teflon envelop embedded in a structure containing the irradiation system UV and visible light sources. On the floor of the chamber sits a tank which can be filled with any liquid/material/chemicals. The liquid filling and emptying can be done without opening the chamber. The cuboid shape of the chamber allows people to enter by a door to manually scrub the walls and the tank allowing to minimize the memory effects of the chamber.
|Services currently offered by the infrastructure and its research environment||
The chamber now well characterized allows the study of interfacial processes and especially liquid/gas interactions. It is equipped with the most advanced analytical equipment to investigate both gas and liquid phases. Morphological characterisation of the particulate matter formed in the chamber and its behaviour when exposed to gases can be studied with Environmental TEM. This instrument is quasi unique in Europe as it allows precise determination of exchanges at macroscopic interfaces.
|Modalities of access and support offered under EUROCHAMP-2020|
|Typical duration of work||
5 days allows to run a blank experiment, a “real” experiment and the collection of the particulate matter samples. These 5 days of experiment include half a day of work on the E-TEM. A study with variable parameters will require 4 weeks of experiments
|Community/user type served||
Users from academic sector (expert and young researchers), SMEs
|Scientific and technical support offered||A research engineer will follow, support and monitor on-going activities.|
|Logistic and administrative support offered||Local logistic support is currently offered to all visitors coming to IRCELyon|
|Person in charge of access provision at the infrastructure||
Sébastien Perrier, research engineer, firstname.lastname@example.org
