    Wolfgang: 

    - PSB: machine given to OP in time scale of one week (Gerd, Martin,Ylenia): firmware flashing, FESA instantiation, ongoing.

    - PSB 4 W amplifier feedback will reduce phase variation up to < 40 MHz to acceptable levels.

    - PS damper fast phase variation with frequency: further improvements only to be implemented after study in lab. For this, connectors are ordered for the 125 Ohm cable; measurements done (Fritz and Reinier), some simulations to follow by Reinier. Residual phase currently at +/-5 degrees (if 4 W amplifiers are modified). 

     After the re-approval of the Impact 156583 access with Reinier to retrieve the old loads for radioactive storage, inspect the kicker tank and make pictures for the grounding. Will try to schedule this for tomorrow, 15.10.20.

    - Access to the tunnel is possible until 22.10.20, then machine will be given to OP.

    - Safety: 

    - grounding in tunnel

    - Four points to confirm from inspection in building 355-R-009; Wolfgang will make pictures for EDMS storage.
