Hi Ben, this is a super helpful guide to EBSD. We met briefly several years ago; even though we never got the chance to work together, I am lucky to be able to learn from you in this way now that I'm starting out with my PhD. Thanks for uploading this series.

Hi James! It's lovely to hear from you, and I'm glad that you are starting out your PhD journey - best of luck, and thank you for the encouraging feedback.

Thank you for your great work, Ben! I was enjoying watching your videos!

Thanks for the watching & the feedback Danyil!

Hi Ben, thanks for the nice introduction to EBSD and basic crystallography :-) very helpful and well explained!

[@benbritton1389]

Thanks for the kind feedback!

Hello Ben,
I have a question that confused me for a long time. According to the Bragg's Law, the 2theta causing diffraction exists bcz of the relationship between the incident electron and the crystal plane. But as 2:41 shows the BSE beam and plane doesn't have a angle of theta. Is it because the incident electron which causes the diffraction is not actually the BSE beam showing in the picture? Thankss!

[@benbritton1389]

Hi - thanks for your query. In EBSD, the electron that diffracts is not the incoming incident electron beam, but instead a scattered electron. This means that the angle theta is between the plane trace (i.e. the centre of the band) and the band edge.

Is that a knitted/crocheted EBSD pattern blanket behind you?!

Yep - it is - made by Dr Vivian Tong
