List of actions:
Experiments:
- Could a Compton polarimeter be installed at KARA? At which cost and which design is needed?
- What is the available space for polarimeter at KARA and could a beam line be used?
Polarization:
- Vertical dispersion matching to be followed up.
- What is the impact of orbit bumps on vertical dispersion and emittance?
- How does it look for W?
- What is the impact of BPM errors?
Effects on ECM:
- A broad study is required to understand the cross-talk between IPs with different collision offsets and OSVDs.
- What is an acceptable value for a RF-frequency shift (dp/p ~ 1e-4?) for OSVD for colliding bunches?
- Define parameters (strength, rise time, etc.) and suitable locations for kickers measuring OSVD for pilot bunches.
Polarimeter:
- Can we benefit from more than one polarimeter, and if yes, at which cost?
- What are the systematics for RDP and FSP measurements?
- What is the best location for one polarimeter?
- How stable is the laser wavelength's central value, laser polarization and spectral width and what is required for RDP and FSP measurements?
- Which laser systems are applicable for pilot bunches and which for colliding bunches?
- How many scattering events do we need for which photon detection efficiency and polarimeter detector requirements?
Depolarizer:
- What are the systematics for RDP and FSP measurements?
- Which minimum beam polarization level is needed (is less than 10% ok) ?
- What is the presently foreseen operation mode (collision on and off or continuously on)?
- Where is the best location for a depolarizer (would next to the final focus work)?
- If the kicks are not closed, what would be the impact on the optics?
- Could the system be combined with the feedback system?
Monochromatization:
- What is the impact of beamstrahlung on monochromatization?
