STF General Schedule K.Yokoya EC at KEK, Sep.4.2008
Boundary Conditions • GDE Plan • TDP1 ~ July 2010 • TDP2 (end of) 2012 • What must be done at KEK-STF • S1-Global • Quantum Beam Project • STF2
Module C Module A upstream downstream S1-Global • Goal • Establish 31.5MV/m in average • Demonstrate plug-compatibility • An important item in TDP1(though cannot be completed by July 2010) • Structure • Module C • cryostat from INFN • cavities: 2 from FNAL, 2 from DESY • Module A • cryostat: same as STF1 module A • cavities: 4 from KEK (existing 4 cavities will be replaced)
Would like to form an international team for • design • installation • operation • FNAL/DESY cavities • expect to get them by ~Oct.2009 • in what form? • INFN cryostat : expected about the same time
量子ビーム(Ryoushi Biimu, Quantum Beam)Project • A new budget framework of MEXT/JST • For beam technology innovation ready for realization • Industries must be involved • 5 year plan. Max. 5 OkuYen per year • We proposed a project “High-Intensity Compact X-ray Source” which includes • RF gun • Laser-Compton scattering • SC acceleration • And were accepted. (Almost guaranteed every year till JFY2012) • 4.5 OkuYen for JFY2008 but this includes • Overhead (23%) • But a good news is that we can employ staffs for 5 years by using this overhead • Planning to add 4 persons for SC (e.g., 2 for cavity, 1 for cryomodule, 1 for cryogenics) • Budget for other fields such as ERL • Budget for participating universities
High-Intensity Compact X-ray Source • Must be demonstrated by JFY2012 • Includes 25 MV SC acceleration and deceleration (but perhaps, deceleration can be omitted) • Beam current (9mA) and pulse length (1ms) same as ILC, but bunch distance factor of ~50 smaller
Better to combine with STF2 for saving manpower and money • Build QB in STF tunnel • Identify 25MV acceleration cavity = STF capture cavity, though QB does not need 2 cavities • Can share the RF gun (but not the laser --- different pulse structure) • But the price is the schedule delay • Interruption for at least half a year, likely ~1 year(installation of QB beamline and tuning for X-ray) • To minimize the delay, plan to finish QB before 2012 summer vacation.
STF2 • ILC 1 RF Unit + injector (RF gun, capture system) • Establish the reliability of the system • Big step to industrialization • Detail under planning. Need one more month.
Infrastructure • Some reinforcement of EP (Nomura KEK) • Long-module related • clean room • assembly area • pathway to underground • Budget and Manpower • ~40 OkuYen needed • Expect little increase of manpower • Out-sourcing • Schedule • Installation can only start in 2nd half of 2012 (due to Ryoushi Biimu) • Debating whether interim operation (1 module) is needed • feedback to the design : realistic? • Cavity production • First batch : 11 cavities (2 for capture, 9 for module #1) • 2nd batch (17 cav.) : when? (KEK and industry capacity)
