Comment to Free space beating installation (69019)

This morning we finished the work on EIB for the ALS part. The next step will be to commission the beating once we will have the green from the arms.

  • We calibrated the monitor photodiodes and connected to the ADC the RF photodiodes. The IR pickoff is around 1,16 W and 26 mW of green beam are produced  (1st attached plot).
  • The IR pickof arrives to the end buildings and the green is produced (plot 3).
  • The total added weight for the ALS part is around 19kg. In the attached pdf there is the list of the installed optics. To be considered that 21.1 kg had been removed at the beginning of the installation (IBMS setup, not used anymore).
