Cables
The Outer Cable is 4-ended cable connecting the outside of the
chamber feed-through plate with the HS controller and SSB board.
The greater / lesser spherical connector connects to the connector
labeled Heating stage / Cooling stage (this is used in case your
system enables both stages, to use only one cable). The 25-pin / 9-pin
connector connects to the HS Controller / SSB.
The Inner Cable is 3 or 4-ended cable connecting the inside of the
Chamber feed-through plate with the heating stage assembly. The 15-
pin connector goes to the appropriate inner feed-through plate
connector, the other ones connect connectors ascribed to the Heater,
to the Sample Bias and to the Thermocouple.

High Temperature GSED
The High Temperature GSED must be installed if the heating stage is
going to be operated above 500 °C (up to 1500 °C), as the standard
GSED could be damaged at these conditions. It is a PLA cap (with
cone) which is pressed onto the standard insert. This cap comes with
a printed board adapter which plugs into the signal connector inside
the chamber. On the other end of this board is a wire which clips onto
the cap.
The detector is located just above the heat shield. Any working
distance can be used.

Note:
The operating characteristics of the GSED and the high temperature
GSED are slightly different.
Installing the High Temperature GSED
1. Vent the specimen chamber and open the stage door.
