4.3 Bake Out Procedure
Note
It is strongly advised to read the following sections completely before baking out the
detector and to strictly follow all given advices within it.
Please also read the bake out instructions in the main manual of the PHOIBOS Analyzer
before proceeding.
The maximum allowed temperature for the detector is 150°C. Do not exceed this
temperature.
After a bake out, the detector needs at least one day to cool down. If channel plates are
operated at higher temperatures (> 70°C) they can suffer damage. Such channel plates
will lose gain and exhibit a markedly higher detector plateau.
Even if the detector housing feels just warm, any internal parts seated on insulators (e.g.
the detector anode) may still be too hot for safe operation. It is imperative that all users
be informed of this issue and take the necessary precaution to ensure proper device
operation.
• The detector electronics (ACU) must be removed before any bake out.
• Windows and feedthroughs should be wrapped with aluminum foil, to protect them from rapid
temperature changes.
• The use of heating tapes and jackets is not recommended, due to danger of local overheating.
• Do not remove the blankets until the entire system has thoroughly cooled off.
• Do not operate the detector before the temperature has returned to ambient conditions.
