Transcript JLab FEL as e-Cooler test facility

JLab FEL as CCR Test Facility
Available Performance
• 0 - ¼ nC (source limited)
• 10-ish mm-mrad, 50 keV-psec
– Can get down to few 10-4 at full energy
• 150 MeV
• 10 mA (source limited)
Critical Technology/Methods/Phenomenology
for CCR
• Source
– Tests of alternatives not an option at modest funding levels
• Beam transfer technology
– Tests of alternatives possible at modest/moderate cost
• e.g. crab cavity/RF separation/recombination
• CSR
– Tests/benchmarks possible at modest cost
• Some now funded/underway at FEL
• Longitudinal Matching
– Bunch length decompression/energy dechirp
– Tests possible at modest/moderate cost
Proposed Technology Validation Tests
• By-pass
– Test bunch train transfer
• RF separator &/or kicker based
• Test longitudinal match
– De-chirp/rechirp
• CSR benchmarks
– MBI/LSC/CSR
– Some tests now in progress
