• BE-OP-SPS suggested then to keep the FT as last year (4.8 s) and run at 3.5e13 ppp (max instantaneous rate)
  • Also, we suggested to increase the duty cycle reducing the MD cycle that will be in the production super cycle
    • Passing from 6 BP to 3 BP => to be confirmed the technical feasibility but no major problems foreseen 
    • Action OP-SPS: check if any technical problem before undertake this option 
  • This would comport an increase of about 10% in average POT/day 
  • No need to discuss with LHC as no impact on filling SC
• Lau and Johannes agreed on validity of the new proposal and will discuss this with the experiments 
  • Action LG and JB: report the experiments opinion on the options presented
