Jour Fixe

NJ, TK, WFP, SS, kHz

• NJ has submitted an abstract for EFTF 2021
• SS had a meeting with Stefanie Kroker to discuss Meta mirrors
• SS will go on parental leave in June and July

• NJ has been working on the Bloch band paper
• SWAP measurements for 20 ms up to 3 s of cooling time → seems to settle after approx. 400 ms
• SWAP measurements for different cooling powers → increasing power up to 550 µW increased the effect of linewidth reduction
  • Check out for even higher powers
• Optimal end detuning changes over time → changed by 400 kHz in ~3 months. Caused by drift of laser? Or VCO?
• After easter setting up of CODT is planned
