Prerequisites, Steps and time needed to reach Milestone #2
(beam through SASE1 an SASE3 beam lines) and #3 (first SASE), assuming that Milestone #1 (beam through linac) has been reached.

Prerequisites: 

Photon beam line closed and evacuated
Technical commissioning finished
Beam Protection System tested (without beam)
Personal Interlock finished 
Radiation Safety approval 

Steps with (dedicated) beam:

each commissioning steps takes roughly 1-2 shifts
(not so sure about times needed for radiation tests)

1. Radiation safety measurements with spontaneous radiation 
(shutter tight?), Personal interlock (?)

2. Beam on FS before mirrors 

3.Test of absorber system 

4.Test of gas monitor system (monitor/

5.Test of slit system 

6. Beam through double mirror system
(beam on FS after mirrors)

7. If beam needs to go to experimental hall: 
Further radiation tests (interlock?) of shutters towards experimental hall
Beam in XTD9 

8. Beam through 600 m of pipe (min. 2 intermediate FS) 

9. Adjustment of focus of mirrors

10.Test of beam protection system / test of beam absorbers (mass spectrometer)

11.Test of BPM at beam line end

12. Beam in experimental hall (Does it have to be focused?)

total 12-18 dedicated shifts for X-ray beam commissioning
