Hi Tyler and DSG,
at noon Dario and Sandro will be in EEL available for RICH
preparation. To my understanding the actions will be:

- disconnect the dewars and plug a N2 bottle
   is there a designated place ?
   can the bottle be fixed on the trolley ?

- disconnect the interlock cables

- put the patch panels in close/safe position

- wrap the RICH with a protective plastic layer

- install a temporary N2 supply line in Hall-B

- put the trolley on its wheels
   can we use the hydraulic jack even with the RICH weight ?
   are the tires all fine ?

- free space in the target area

Thanks, Marco.
