field emission gun refurbishment

YPS refurbish thermal field “Schottky” and cold field emission electron guns and source parts for electron optical instruments. This is especially useful, where budgets are restricted and continued use and performance improvement is sought.

Our capabilities mean that we are able to service a wide range of instruments, including SEMs, CD-SEMs (e.g KLA Tencor’s KLA 8100, 8100E), electron beam lithography and electron microprobes. Please contact us for your specific requirements. 

We also offer an upgrade service from thermal emission sources to thermal field emission i.e. “Schottky”, where performance improvement is required.
