Removed and replaced the annulus ion pump for GV15. No issues were encountered during the replacement, after new pump was installed the annulus system was pumped for about 3 hours with an aux pump cart. After 3 hours the ion pump was able to maintain vacuum, thus the aux cart was decoupled and turned off. GV15 Annulus ion system back to nominal.
Done per WP#8009.
