Achievements

• Work on laser to improve the beam profile and reduce pointing. Apertured the beam upstream of focusing lens and changed to f=750 mm. Significant improvement.
• Characterized beam size, found positions of photodiode, antenna
• Check coarse timing with reference
• Aligned FEL beam to sample

Problems

• Problems with smaract stages
  • Fixed with the help of DOC (Loic) by power cycling controller after long debugging.
• Beam down just before attempting coarse timing.
