Stereoscan Operators Log

While repairing, maintaining, or using the Stereoscan S200 SEM, please add notes here. Newest at top.

• From Tim: the red vacuum gauge sticking out of the back of the chamber is a cold cathode vacuum gauge. They're pretty reliable, but it could fail to read vacuum, indicating it needs to be cleaned. Plasma (talk) 13:07, 2 April 2014 (PDT)

• The following steps need to be performed on the Edwards roughing pump:

• • Replace the oil
  • Inspect and clean the inlet-filter
  • Clean or replace the gas-ballast filters
  • Clean the motor fan-cover
  • Test the motor condition

Refer to pg. 38 of the user instruction manual

• March 31st: Cleaned the plinth and took photographs of the vacuum components. Available here. -Dan K.

• Oil diffusionTurbo molecular pump was hanging due to the lip falling out of the rubber suspension. Could be cleaned and probably popped back in.

• Broken switch on roughing pump was bypassed internally. Plugging in the outlet should activate the pump. (This pump normally runs 24/7 when the machine is operational.)

• Compressed air needed to get more dust out

• March 30th: Moving complete! The SEM is now in the workshop

• March 29th: Awaiting pick-up and installation (March 29th and 30th).

• March 23rd: A space in the workshop has been cleared. Photo: http://i.imgur.com/BDNWL5z.jpg
