I am planning to have LEO and RAITH Field Service personnel come to SNF 
to perform alignments and maintenance as well as to resolve the EHT 
arcing problems we have been experiencing recently.  This will result in 
some unexpected and scheduled downtime to users.  I am hoping to get LEO 
in this week if possible to perform the alignments to the 7.5 and 120 um 
apertures centering functions ASAP. This will likely eat up a half day 
of day time usage.

Raith Field Service along with LEO experts will be coming in next week  
and we could be down for several days to perform more bake outs and 
resolve the arcing issue. (days and times TBD) I have already blocked 
some time on CORAL next Tuesday and WED. but will offer these times up 
to the community if they are not needed by the Field Service people.

My suggestions to All Users is to maximize your usage and throughput 
this week in order to get as much work completed on the system as you 
can before we come down.

Thank you for your support!
