Ion Optic Supply Board
Figure 1-33 shows the ion optic supply board (P/N 209 9810) 1 . The
board is located in a housing on top of the left instrument side of the
instrument. This board supplies the voltages and the radio frequency for
the ion guides and interoctapole lenses of the LTQ Orbitrap XL. It has
an RF detector for the RF output control. The board also provides the
trap voltage, gate voltage, and reflector dc voltages as well as the
RF voltages to the octapole 1 of the Orbitrap. See topic “Orbitrap
Analyzer” on page 1-13 for further information. Furthermore, the board
provides the voltages for the HCD collision cell. See page 1-18.

The diagnostic LEDs listed in Table 1-13 on page 1-47 show the status
of applied voltages to the board. The position of the LEDs on the board
is indicated by white rectangles in Figure 1-33.
Warning Parts of the board are at high voltage. ▲
