Current planning calls for PEP-II to be operated until the end of FY2008 at the latest, and the Tevatron collider to be operated until

the end of FY2009. What factors or considerations might lead to stopping B Factory operations one year, or two years earlier than

planned? When would we be in a position to make such a determination and what information would be needed?

New RF comb filters (Fall 2005)

New klystron linearizer (Spring 2006)

Install LER-5 RF station (Fall 2006)

Install HER-10 RF station (Fall 2006)

Upgrade several high-power IR vacuum chambers (Q2, Q4, Q5, Q2 bellows, LER abort spoiler, straight section bellows ) (Fall 2006)

HER lattice upgrade for lower momentum compaction and shorter bunches (Fall 2006)

Fix LER BPM heating issue (Fall 2006 if not before).

The missing channels

At one year from the installation 5 wires over 1552 are in a hospital PS at lower voltage.

Few other HV channel are connected in the hospital PS (no loss of efficiency).

The problem of the hospitalized channels can be in the HV distribution (cables, capacitors), indeed all the plateau are good: this can be investigated during the October shutdown.
