I was talking to the Hallendienst concerning the mag shielding. For the 
installation itself we should assume half a day. But there are certainly 
more things to be done:
- At the moment we have on the floor a drawn line indicating the beam 
line. This will be hidden after the installation. Do we want to have 
this again on top of the shielding?
- It certainly might be a good idea to fix the shielding on the ground. 
Is there somehow need to fix the tracks of the hydrogen target on the 
shielding?
- There could be need for further alignement by the survey group. This 
depends on the constructional layout (is something connected with the 
shielding or not?
I personally have too less knowledge on the MuCap installation (for 
example details of the target) to be able to judge on the design. But 
regarding these additional tasks, the guy from the Hallendienst said it 
might easily take a day (if not a bit more than that)

I just phoned Dr. Ootani from the Muegamma group. They are not able to 
switch on the magnet until beginning of November since they are in 
maintenance and therefore they cannot cool down the system.
