Dear users, This afternoon we found that the cooling system for LS1, circled in yellow in the attached photograph, had been turned off. It should be left on to ensure the lasers are cooled to 18oC and never turned off, as this can cause laser over-heating and damage to the lasers and microscope. Please DO NOT TURN IT OFF when shutting down the system. Many thanks for your cooperation. If you are not sure how to turn off the system, please look at the instructions in the folder on the desk or ask a member of FILM. All the best, David ---------------------------------------------------- David Gaboriau, PhD, FRMS Microscopy Specialist Sir Alexander Fleming Building South Kensington Campus Imperial College London Exhibition Road London, SW7 2AZ SAF 4th floor, open space desk 408 +44 (0)20 7594 9793 d.gaboriau@imperial.ac.uk https://www.imperial.ac.uk/people/d.gaboriau http://www.imperial.ac.uk/medicine/facility-for-imaging-by-light-microscopy/ ---------------------------------------------------- [cid:323a7a8b-de4d-4601-86ee-c1d46c90b31d@GBRP265.PROD.OUTLOOK.COM]
