Dependence on compression (R56) Dependence on
horizontal beam size during compression Dependence
on shielding environment
2
Investigation of CSR effects on beam phasespace
distribution at CTF-II
- Transverse emittance growth - Beam energy
loss - Increase of momentum spread -
Benchmarking of simulation codes - Investigation
of shielding by parallel conducting plates
3
Experiments on CSR with the CTF-II bunch
compressor chicane
Measure as function of R56 - rms bunch
length - mean beam energy - energy spread -
transverse emittances Measurement for 5 nC and
10 nC per bunch
( Results excepted for publication in PRST-AB )
4
Observables after bunch compressor (5 nC)
5
Bunch energy spectra after compressor (5 nC)
6
Observables after bunch compressor (10 nC)
7
Bunch energy spectra after compressor (10 nC)
