1. Turn off the high voltage source of ICEMS (down to 0, then power off)
2. (dosimeter) Remove the preamplifier ICEMS
3. (dosimeter) Remove the detector from the optical bench
4. Remove the screws that allow you to open the detector
5. Remove the plastic nuts that hold the upper electrode of the detector, separating the upper electrode and remove the previous sample (careful not to scracth the top electrode)
6. If the top electrode is scratched or an arc has happened, clean it with alcohol (never with acetone) and cover it with graphite
7. Mount the sample on a slide so that the hole is completely covered
8. Reassemble the upper electrode
9. Close the detector
10. Fill it in acetone (separate instructions)
11. Put the detector in the optical bench with the source at ~ 1.5cm
12. Check that the transducer moves
13. Connect the wires to the preamplifier (signal, power and HV)
14. Increase HV to 1000V at once
15. Increase slowly and watching for arcs, typically up to 1500V
16. The LED on the amplifier must be almost solid red
17. In the program, select PHA with the window fully open
18. Remove the part of lowest energy, typically <400mV
19. Back to MCS (Window), clean and acquire
20. The pulses will increase according as the acetone "settles" (heats up), so wait at least one hour before turning up the voltage (up to 1850V for  some samples, but there is danger of arcing at higher voltages)
