Greetings Raith Community

This is your notice and second announcement that we will be taking the 
RAITH 150 system off line for up to a weeks time to replace the LEO SEM 
column with a brand new SEM column. 
Tentatively Monday June 6, 2005 to possibly the end of the week Friday 
June 10 the system may be off line to all users. I hope to have it back 
up and available for testing Thursday evening and open for all users mid 
day Friday if humanly possible.

This is to allow us time to replace the SEM column with the new column, 
perform a normal column bakeout, and then to make adjustments to the E/O 
card and SEM column. This period should also allow adequate time for 
testing and performance characterization before returning the systems 
for users.

This effort is made to eliminate the column scattering issues that has 
negatively impacted most users working on the system.

Thank you for your support!

James Conway
