Revision as of 20:40, 9 April 2013

Configuration

Secondary electron detector (functional)
4 quadrant silicon backscatter detector (non-functional, troubleshooting in progress)
Oxford Isis EDX detector (non-functional, requires liquid nitrogen to operate)
High Resolution Recording Unit (HRRU) (not currently connected, Polaroid film no longer produced)

Certification

This is probably the most complex piece of equipment we own. As such, certification will be broken into different levels which qualify a user to perform only a limited number of tasks. Unlike other PS:One equipment where anyone certified can, in turn, certify anyone else, at present the only person who may certify others is Ryan Pierce. We anticipate we will have additional trainers in the near future.

Microscope User

This level enables the user to observe samples already prepared and placed in the chamber. Users at this certification level may:

Observe samples already left in the chamber.
Observe their own samples if prepared and placed in the chamber by someone with Sample Preparer certification.
Adjust beam current and aperture, and change between apertures.

Users possessing this certification may not:

Vent the chamber
Open the chamber and manipulate samples
Adjust gun alignment
Open the gun assembly, change filaments, anodes, etc.
Replace apertures.

Sample Preparer

Curriculum in progress. The sputter coater will need to be ready for use before we can certify users for this.

Microscope Maintainer

Maintainers perform all maintenance on the microscope, including:

Changing filaments
Aligning the gun
Replacing the anode
Cleaning the gun assembly
Replacing apertures
Adjusting software configuration
Anything involving disassembly of the microscope

Maintenance Log

Date	Maintainer	Description
4/7/2013	Ryan Pierce	Installed new CPU fan. Finished replacing all panels except for the CPU.
4/?/2013	Ryan Pierce	Hacked CMOS battery from battery holder and 4x AA batteries. Had to change jumper on motherboard, per manual, to use external battery as opposed to on board battery.
