Goals

  • Converge on what to put in the Q0 paper/poster and good deadlines

Discussion items


TimeItemWhoNotes
1


Half on method, half on results
2


Dan will send plots

3


Tried to calc heat by how much liquid boiled at Fermilab (super complicated because need to understand geometry)

4


Normal (decay) method doesn't work because loaded Q measurement is overpowered by measurement of coupler q (3 orders of magnitude). reverse true at room temp with network analyzer

5


Talk about repeated measurements of the same load for error (about 2%)

6


Net error is ~20%

7


Communicate effect of degaussing (poster can have bar chart)

8


Single cavity Q0 (is real Q0)

9


CM Q0 is not real Q0 

10


Say that exceeds spec

11


No fast cooldown (Dan has a poster)

12

Ryan

Should the poster focus be on measurement or results?

13

Dan

Poster should have both (not shown anywhere else besides Dan's talk)

14


Why didn't we degauss all? Management, schedule constraints, etc. Lesson learned, will do in future

15

Ryan

Estimate what we can get Q0 to?

16

Sebastian

No

17

Dan

Somebody asks, say our experience is we can get bad ones to 3e10

18

Dan

When Qs go above 3/4e10, error goes up

19

Dan

Make poster before paper because of timing

20

Lisa

Make confluence page first to get method organized then convert

21


Review how to tex

22

Sebastian

Try not to duplicate effort between tex and powerpoint, we'll work on it

23

Ryan

As few equations on poster as possible

24

Sebastian

Need some to describe
