KEKB review commi5ee

KEKB to SuperKEKB•

KEKB status– We achieved new peak luminosity record of 2.1x10^34 /cm2s with crab
crossing by tuning chromaJc x‐y coupling with skew‐sextupoles.
– Integrated luminosity of 1000 M‐1 has been delivered to Belle, which isconsidered as a goal for the present KEKB.

•Nano beam
– Following the recommendaJon by the last review commi5ee, we started thedesign of nano‐beam opJon for SuperKEKB.
– In the fall of 2009, we decided to adopt this scheme, changing from the high‐current scheme.

•Belle‐II– Belle‐II collaboraJon was established based on the Belle team, and newmembers are joining.

Budget allocated so far– Besides the annual operaJon budget, new budget has been allocated:•FY2009 Supplementary Budget of 25.5 Oku‐Yen (1 Oku‐Yen = ~1.1 M$) wasallocated to KEKB for development of low‐emi5ance beam device.
– This budget is being used for fabricaJng a part of ante‐chambers for the LERwiggler secJon, reinforcement of RF system, and R&D for key components
such as IR magnets, positron source, etc.

•FY2010 a budget of 5.83 Oku‐Yen was allocated for KEKB reinforcement.
This single year budget is the ﬁrst year of three‐year plan for the Damping
Ring construcJon in total of 25 Oku‐Yen.
– An announce was made abroad by the DG of KEK as "The Japanese
Government has announced KEK's budget for JFY2010, in which preliminary
approval was given to the KEKB upgrade program, and a budget was allocatedto parJally start construcJon. This does not yet consJtute full approval of theoverall project, but can be interpreted as a provisional decision by theGovernment in these diﬃcult Jmes of drasJc change in the JapaneseGovernment."

Commi5ee for large‐scale projects•A commi5ee that discusses large‐scale achademic projects wasestablished last year under Science and Technology, Academic Council in
MEXT.
– The commi5ee discusses ways to promote large‐scale achademic projects inJapan.
– Roadmap in each research ﬁeld is being discussed in the Sience Council ofJapan, which will be submi5ed to the commi5ee. The commi5ee will discussand se5le on the roadmap. The commi5ee is to decide which projects to bepushed forward in coming years.
– The decision will be made by this summer, hopefully.

PresupposiJons•

We present fastest possible schedule with following presupposiJons:– Not a small part of budget allocated to KEK in JFY2010 be assigned to KEKB
upgrade by the KEK ExecuJve Board.
– PosiJve decision be made by the commi5ee for large‐scale projects in MEXT
by this summer.
– Budget for the Damping Ring tunnel and buildings be allocated in JFY2011 bythe Japanese Government.
– Full approval of the overall project, SuperKEKB, be made in JFY2011 by theJapanese Government.

About this table–––•FTE needed(A)

Needed FTE is esJmated based on the number of working staﬀ during KEKB construcJon.
The HR for the Linac is not included in the list.
Similar esJmates were done in the Accelerator Laboratory. The result shows 78 FTE short in total(107 short as of Apr. 2013) if all projects wri5en in the KEK roadmap be persued at the same Jme.

How to ﬁll the short FTE?
–––

New persons? (usually only a few persons are newly hired each year in the whole Accelerator
Laboratory.)
What we can do in the Accelerator Laboratory is being discussed.
Will priority among many projects in KEK be clearly deﬁned?

9Summary•Schedule– KEKB and Linac team prepare for the fastest possible schedule, whereSuperKEKB commissioning start at the beggining of JFY2014.

•Budget– Budget plan is presented. We will reﬁne it as the design progresses.

•Human Resources– About 30 FTE is short for SuperKEKB construcJon. We have no clear answer atthis moment, but anyway we must solve it.
