We moved the new detector installation for the first time slowly into the dipole chamber.
The alignement seems to be pefect, no distortion or vertical movement of the detector-arm was observed from the window flange.

The vacuum on the detector side went up from 2e-10 mbar to about 5e-9 mbar.
On the ring side it was 3e-11 mbar befor and 1e-10 mbar after movement.

The extreme positions possible (Endlage) are:

max out: -10613 
max in: -7

These are the absolute positions in units of 0.1 mm

It has to be noted that after bakeout a realignment of the detector was needed in order to have it centered in vertical dimension. However, this realignment has been only slight turns of the base flange alignment screws. In detail, the two inner "Sechskantschrauben" below the bellow have been loosed slightly, while the outer two have been tightend. Additionally, the small "Madenschraube" on the outside has been loosend by 1/4 turn.
In result the detector could be raised in vertical position by about ~5mm (jugded by eye).

The effect of small turning on the screws is extreme on the detector position! Be careful when re-adjusting.
