[Tgun] [EXTERNAL] RE: First beam!

[Shinn, Michelle]

Dear Fay et al.,

Congrats, I am so excited to see the start of beam delivery - now on to seeing what sort of beam!
I'll savor a virtual donut next Monday.

Regards,
Michelle

Subject: First beam!

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
