2 Preliminary tasks
Before using the detector, you need to perform standard procedures so that the detector is ready
for use.
Note
Initial installation and alignment is performed by SPECS engineers on delivery of the instrument.
These procedures are provided for reference in the Appendix of this manual.
This chapter describes the following:
•
Bakeout.
•
Suitable vacuum conditions for operation.
•
Conditioning the Spin detector .
•
Electrical connections.
•
Fitting the camera for the CCD detector.
•
Degassing the detector.
Baking out 2.1
In order to achieve UHV, you need to bake out the chamber. Before baking out, you should ensure
the following:
•
The chamber is leak-free with a pressure of 10
−7
mbar or lower.
•
All connection cables are removed.
•
The cameras are removed.
Switch off any power supplies before removing cables.
The maximum bakeout temperature for the 2D-CCD / 3D-VLEED Detector is 150°C. You should
attach a thermocouple to the detector flange to monitor the temperature during bakeout.
Note
Remember to observe the maximum bakeout temperature for all other instruments on the
chamber!
After baking out, the analyzer needs two days to cool down in order to protect the working
surfaces of the detector. The interior parts of the PHOIBOS will cool down significantly more
slowly than the casing. You should wait until the detector assembly has cooled down completely—
this takes approximately 2–3 days.
Caution!
