I have called Raith USA Inc. and asked them to put in a service request 
with Zeiss SMT.
I have a reservation next Friday on CORAL to perform this routine and to 
check other items on the system as well.

Thank you for your support!

Good Morning,
User Topinka and DGG group reported that the 120 um Gun alignment settings were approaching the limits of the adjustment range.
Today I checked this out and determined that we may need to perform a mechanical gun realignment before we can properly align the 120 um aperture Gun alignment setting properly.
This may or may not have been resultant from last week's Power drop to the system -- but likely just a normal consequence of running in the FE-GUN.
(Current time on FE Gun -s 1537 hours emission time.)

Note: After the recent FE_GUN tip exchange ZEISS Field Service DID NOT return to complete the final aperture and gun alignments.  The was no further response to our request at that time.  2 phone calls were left unanswered.  I called RAITH USA today and requested they schedule a service visit for us on next Friday to perform adjustments and update the system settings. (Joel at RAITH USA Inc.)

Best,

James Conway
