Analyzer Checks
Figure 32: XPS on Silver, Ag 3d (PHOIBOS 150 MCD9)
Parameter for the Ag 3d spectrum in figure 34:
Lens mode: Medium Area
Slit: 2:7 x 20 mm / 2:open
Sample current: 160 nA 300W Mg Kα
Detector voltage: 1950 V
If no spectrum but a straight line appears after the control unit has been started, either
no pulses are arriving at the control unit counter, the counter is defective, or the spec-
trometer voltage U0 is missing. The following checks should be made:
1. All cable connections (Figure 2: Connection Scheme page 7) between has 3500
and Detection box PCU 300 the computer and the EC10 Ethernet-Can-Adapter.
2. Control Unit Check, see section
3. Preamplifier, see section 9.1
4. Section 9.2, “Detector Voltage” on page 76.
8.4 Connection Check of the Analyzer Electrodes
In addition to this test, the correct generation of the spectrometer voltages should be
checked (see section , "" on page ).
