Spare Parts
10.1 Cu Gasket
All CF gaskets are custom made by SPECS. In case you need a replacement please con-
tact SPECS, because it depends on the release of the analyzer.
The serial number of the analyzer is marked on the lens flange.
10.2 Multiplier
1. SCD, Single Channel Electron Multiplier replacement for PHOIBOS analyzer
2. MCD, CEM Array replacement
5 channels MCD for PHOIBOS analyzer
9 channels MCD for PHOIBOS analyzer
Please indicate the serial number of your analyzer (flange at the lens housing, e.g.
33.04) in the replacement order. The order of a single channeltrons, a set of channel-
trons or a complete replacement of the detector flange including channeltrons is pos-
sible.
10.2.1 Channeltron Handling and Storage
A channeltron or a channeltron array (array of 5 or 9 of single channel multipliers,
fused together in a precision matrix) is a high gain device for detecting energetic
particles such as electron and ions, or radiation. The channeltron consists of a small,
curved glass tube. The inside wall is coated with a high resistance material. The resistive
material becomes a continuous dynode when a potential is applied between the ends
of the tube. It is fabricated from a lead-doped glass. Proper handling is required and
the following precautions must be taken.
10.2.1.1 Handling of the Multiplier
●
Shipping containers should be opened only under clean, dust-free conditions.
●
No physical object should come in contact with the active area of the detector.
The channeltron should be handled by its solid borders using clean, decreased
tools fabricated from stainless steel, teflon (PTFE) or other UHV compatible
materials.
