End of Shift Procedure
======================

This section describes the procedure to put the instrument in safe conditions at the end of a shift.

1. **SA3 beamline**

* Stop mono scan.
* Stop mono gap sync .
* Set number of pulses to 1.
* Stop injection to GATT (if the next injection is not expected to happen in the next 1 hour or more).
* Insert pre-absorber.
* Extract TPI.

2. **PP laser**

* Close the laser shutter.
* Turn the key to disable the laser interlock.
* Set the number of pulses to 1.
* Stop delay scan.
* Turn OFF the LT3 motor.
* Stop the online monitoring tool for fine timing.

3. **SCS beamline**

* Close all beam line gate valves *while monitoring the pressure in each section*.
* Insert B4C at DPS-2.

4. **MCPs or APDs (TIM, CHEM, XOX...)**

* Set all MCP and APD HV to zero and turn them OFF.

5. **XGM / HAMP**

* Set voltages of the *HAMP h HV MP* to zero, power off the corresponding channel.

6. **DSSC**

* Turn off the DSSC following the appropriate procedure.

7. **CHEM**

* Open filter towards hRIXS
* Close valve towards hRIXS

7. **XRD**

* Open filter towards hRIXS
* Close valve towards hRIXS
* Turn off all XRD motors.

8. **hRIXS**

* Close all valves between vaccuum sections and towards bellows
* Stop camera

9. **DAQ**

* Ignore data (in Run Controller scene) both  in SCS and SA3 topics.

10. **Radiation interlock**

* Make sure the shutter can be safely closed.
* Close the shutter.
* Break the radiation interlock.
