Agenda
1. Aims this meeting (GE) (5mins)
2. Aims of ILC Collimator tests (5mins)
Benchmark
ANSYS simulations for velocity, displacement and stress
Characterise
material – failure criteria at high strain rates
To
enable design to proceed with no failure envelopes
3. a) Possible types of test, how to
stress material (5mins)
Talk on damage studies (from DL ELC meeting)
Beam SLAC KEK etc.
-measurements in electron beam at ATF
George’s
rough comparison of beams
Other heating, such as Chris’ setup?
b)
How to measure the effects
VISAR
SHOCK ANALYSIS USING THE MULTI POINT VELOCIMETER
(VISAR)
From
page 11:
The
measured particle velocity can be plotted as a function of shock velocity. By
knowing the values of shock velocity, particle velocity, and density, the
compressive pressure can be calculated
using conservation of momentum:
