c. Gently lift up the thermionic source connector guiding the flexible cable from the
thermionic source support, then remove the thermionic source assemble from the
NPD body. Avoid bumping the bead on the sides of the collector. See
Figure 260. NPD Thermionic Source Removal (3)
12. Remove the collecting electrode and the insulator. See
a. Using a 6-mm wrench, unscrew and remove the collecting electrode pin from its seat
on the detector body.
b. Using forceps or tweezers, extract the collecting electrode through the top of the
detector body.
c. Using forceps or tweezers, extract the insulator through the top of the detector body.
Place the insulator on a clean surface.
