Booster - RF• Anodes– Preparing for FY14 shutdown install

• Specifications were agreed upon in early spring• Design developed and approved• Schedule of construction, testing and install (tight) provided• Ordering components

– Most items appear to be deliverable by required date but ….» Some items are long lead times» Several components are not standard – requiring more engineering time

to look at alternate options» Limited testing time - may result if late delivery

• Began software/controls• Reviewing testing (MI60 option) and install options

• Bias Supplies (10 supplies) (East gallery Completed)

– Upgrade the West gallery Bias supplies Transformers• Heat sinks

– One supply completed/tested, 2nd ready for testing , 3rd 50% done7/8/2014

Cavity and Tuner Refurbishment• 10 of 19 stations have been refurbished for 15Hz– Recent work rate is about 10 weeks per cavity– Additional labor has been supplied to effort• New hire is a full time employee• New contract technician• Training takes several months

– Process continues to be refined and documented– 4 refurbished cavities have had to be pulled and

reworked• Taper failure on 2 cavities (not part of refurbishment)• Two early refurbished cavities – failure of flange connection

– method of milling to resurface remedies this problem

– Still working on new cone options (to speed up work)7/8/2014

Cavity Refurbishment

7/8/2014

Additional cavity work added to the refurbishment process is the inspection and sometimes necessary repair of the cavity taper.

Two stations (located at RF3 and RF5) have required to have their downstream taper repaired. The work requires the end of the cavity to be cut off, ceramic window replaced and taper reworked.

The first of the reworked taper cavities is undergoing high power testing. This cavity also has the new tuner.

Scorched Ceramic Window (due to sparking)

Window and end of taper removed

End of taper removed New taper extension

Working on schedule and testing:15 Hz testing and shutdowns (this year and next)Need to verify 15 Hz operations – find unknown issues

Full 15 Hz system testing and operations can only begin when all installed cavities have been refurbished.

Tuners - New• Will speed up process• To build up inventory• Will help reliability/uptime• Reduce worker exposure rates

7/8/2014

The first new tuner took about 1.5 weeks to build.But extra time was spent on documenting the procedure (TD).

The new tuner has been installed on a cavity and is now undergoing high power testing. The plan is to verify its performance and then place a ferrite order.

PIP Milestones

PIP PMG

Summary

• FY14 PIP – Progress has been made on all scheduled tasks. Critical items like refurbishment and new tuners have made significant progress but no improvement in schedule. An increase in labor has been beneficial in moving several tasks along and should help to meet the milestones goals.

• PIP continues to adjust to changes in budget and planning – recent work on FY15 budget and PIP II plans are being worked through.
