Removing the Ion Shield

When cleaning a TEM holder that does not have a sample installed, you may 
remove the ion shield in order to increase the cleaning speed (although it is not 
necessary). This should not be done if a sample is installed or the sample may 
experience ion damage. To remove, unscrew the ion shield (counter clock wise).
