4.3 Bake Out Procedure
It is strongly advised to read the following sections completely before baking out the
detector and to strictly follow all given advices within it.
The maximum allowed temperature for the detector is 150°C. Do not exceed this
temperature.
Note
Keep in mind the description about the important operation details in
Note
Turn off the high voltage, close the software and turn off the TDC before performing any
changes of the cabling.
The detector operation voltage “
MCP-B
” is given in the specification sheet. It is always
given in reference to the MCP front voltage “
MCP-F
”. The maximum reference voltage for
“
MCP-F
” is also given in the specification sheet.
The Surface Concept HV Power Supply is a floating HV device. The reference voltage
must not explicitly be added to the operation voltage. See the manual of the HV Power
Supply for further information.
Note
Example for voltage ramping:
Assume the following operation voltage for “MCP-B” in respect to “MCP-F”:
+1,900V and a reference potential for “MCP-F” of +1,000V. A ramp time of a few minutes should be used to
increase “MCP-B” to +1,900V. Then a ramp time of approx. 3 min. should be used to increase the external
reference voltage from 0V to +1,000V. Now the actual output voltage of the Surface Concept HV Power
Supply in reference to the GND potential would be for “MCP-B”: +2,900V (1,900V + 1,000V) and for “U_
DLD”: +3,300V (“MCP-B” + 400V), because the HV Power Supply is floating on the reference voltage.
