6. Maintenance
Following these maintenance steps will insure normal and reliable operation of
the system. This maintenance is intended to be performed by the operator.
1) Fan Filters
Once a month clean the cabinet fan filter.
2) Sample Chamber
The stage might have a problem if the chamber is not clean, especially if
volatile liquid or porous materials contaminate it. In a dirty chamber, there
always exists the risk that some particles or liquid will accumulate on the
surface of the thin Be window.
3) Si PIN Detector
The detector window is made of Beryllium foil, only 12.5 microns thick.
Beryllium is a very corrosive element: water and many other liquids and
particles can interact with it and generate pinholes within a short period.
The result is loss of the vacuum in the detector cryostat.
4) Follow the maintenance instructions in the computer's manual to assure
its proper operation.
7. Troubleshooting
This sub-section offers assistance in correctly diagnosing and possibly
correcting common problems. Emphasis has been put on problems that arise
from incorrect operation or settings, or other difficulties that can easily be
corrected by simple means. In general, only trained service personnel must
solve hardware problems.
An accurate description of the problem is essential for the effective assistance
from the service department. When dealing with a problem related to operation
or analysis results, the most effective initial step is to relate the problem to one
of the following main categories:
1. Hardware or software
2. Method and/or data associated with problem
3. Operator/Operation
Any connection between the problem and an action preceding it or an
environmental cause may help in the identification of the problem's source.
Warning:
Do not attempt to repair the system on your own. Consult your
service agent before trying to repair any hardware failures.
