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 invited facility staff and users to join in with our 75 years of science with synchrotron light celebrations.

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

Type of memories submitted:

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!


The community was invited to choose their preferred format.  It could be a photo with a caption, short story, audio/video recording of the memory, a poem, song, artwork, comedy sketch, short play, post for Instagram or Twitter etc.  Whatever format people were comfortable was fine by us!


Now that all the #My1stLight memories have been gathered in, we will be sharing them via this page and social media over the next few months.

We hope you enjoy this trip down light source memory lane and would like to thank all the participants for their submissions.
