Dear Alex, all,

 

We have prepared some slides for today’s update.

https://docs.google.com/presentation/d/1n-4rhh_M66L-6ieXzLnXoQSzS27gDsjcpstlHiNoj68/edit?usp=sharing

 

Summary:

• We performed two coatings last week – Evaporation 15 and 16, after an interruption from a chiller broke down.
• We confirmed a narrow range of Aluminum thickness that is optimal for our reflectivity. A few more coatings will be followed up this week to gain more insights. We plan to complete our “recipe adjustment” by the end of this week.
• Upgrades preparations (ion-gun mount, full size mirror mount, feedthroughs) are nearly done. Upgrade may start as soon as at mid next week.

 

Let us know if you have any questions.

Thanks!

 

Preet, Jinfeng, and Kong

 

Ps: this is the last week of the summer intern program for Jinfeng, we thank him for his excellent works for contributing to the pfRICH mirror effort!

Good afternoon,
