Subject: NBI Upgrade Weekly Status 6/4/10
Al,

NBI Upgrade: Preparations continue on PDR presentations on all jobs.  On Vacuum Vessel modifications, plasma cutter testing on thick stainless steel continued using a Nitrogen shield gas. Results are very promising. Very little post-cut grinding is necessary to prepare surfaces for welding. WAF scrutiny continues to refine estimates.

NBI Decon:  Decon wipedowns continued on the interior of the beam box. Decon spray continued on the calorimeter. Decon continued on the ion dump louvers in the fumehoods. Test Cell area maintenance has been performed on a routine basis. 

Regards,

Tim
