Celebrating 75 Years of Science with Synchrotron Light with #My1stLight campaign

Welcome to our #My1stLight campaign page!

“The first observation, literally since it was visible light that was seen, came at the General Electric Research Laboratory in Schenectady, New York, on April 24, 1947.”*

The synchrotrons and Free Electron Lasers within the Lightsources.org collaboration invite facility staff and users to join in with our 75 years of science with synchrotron light celebrations.

Calling all light source staff and facility users

Lightsources.org is inviting all those connected with light source science to share their #My1stLight memories so that we can celebrate the amazing journey that the field has been on during the past 75 years.

Type of memories we are looking for:

1st day at work at a light source

1st time you used synchrotron light for an experiment

1st time you visited a light source

1st time you learnt about synchrotron light (and your thoughts at the time!)

1st time you worked on a component for a light source

Any other light source related 1sts!


Choose your preferred format.  It could be a photo with a caption, short story, audio/video recording of your memory, a poem, song, artwork, comedy sketch, short play, post for Instagram or Twitter etc.  Whatever format people feel comfortable with is fine by us!


Please submit your #My1stLight memory using the form below by April 30th 2022


If you have any questions prior to submission, please do contact Silvana Westbury, Project Manager, at webmaster@lightsources.org

Thank you so much for being part of this campaign!
