Dear All,



A happy update - we did it! Yesterday, with Mark driving, we saw first beam from the Xelera SBIR thermionic gun. A huge amount of work and effort went into producing this first graph of the emission cut-off voltage as a function of gun high-voltage, and we are immensely proud and excited.

Congratulations and thank you to the extended team at Xelera and JLab. This is just the beginning – watch this space!



Come join us in the LERF breakroom, Monday 9th @ 11am, to celebrate with donuts.



Best wishes,
Fay
