What hardware (modification) is needed?

• KFA 53 is a complete new kicker system: • Vacuum tank • Delay line magnet• Pulsed/Controls Cables• Generators (PFL) • Controls • Infrastructure (building, cable ducts, electrical

installation, etc.)

LIU-PS ABT review 5

Received Requirements

• As fast as KFA-45 (rise time 46 ns 1-99%).• Max. deflection angle at 2 GeV: 1.3 mrad.• Beam stay clear aperture: 140x53 mm . • Magnet to be placed in SD53.

LIU-PS ABT review 9

• KFA45 area is crowded already (although controls consolidation could free up some space)

• Cables to SD53 would be too long.

Space• 365-1-405: No space available. Cables too

long (should be <50m).• 362: seems to small.(extension?) Cables too

long.• 365: (east end). Seems ok but TE-EPC

owned.• 356: possibly best location but TE-EPC

owned.• If none of the above is possible: New building

between 365 and 356.

Concept and Main Parameters

1/10/2014


Basic Concept for Magnet (I)• Delay line magnets. • Leave aperture for possible impedance

shielding efforts (+6mm=59mm). • Adapt magnet to rise time requirements in

SC mode.

• Hence KFA 45 modules will not fit anymore (53mm).

1/10/2014


Basic System Concept (II)• Beam rigidity at 2 GeV is 9.29 Tm;• Magnetic length is ~650 mm; • 1.3 mrad kick requires ~850 A;• Usage of RG220 cables desired; • Thus max. 40kV ops max. 33kV nominal 27

kV. -> 27kV/0.85kA -> ~30 Ω system impedance.

1/10/2014


Basic System Concept (III)• 2 delay line magnets to be housed in new

vacuum tank. • Usage of known 60 Ohm low loss cable ( 2

in parallel). • TX cables loaded with ferrites for pulse

shaping.• Refurbishment of 2 EPA generators. • CX 1154 Switches. • Hydraulic group (ELENA type)

Manpower / Resources

1/10/2014


Manpower/Resources• No detailed manpower planning available yet.

• Conceivable that additional manpower is needed.

• Integration/design effort to be estimated and requested at design office.

• Assembly area for magnet and generator will be 867 (within controlled zone).

• HV-Test cage for system testing needed in 2017.

1/10/2014


Other: Consolidation of KFA-45

• A refurbishment of the KFA-45 controls is envisaged as very similar KFA-53 controls needs to be developed anyway.

• The replacement of the KFA-45 SF6 cables is foreseen.

• Extension of cable shed for spare cable drum to be discussed.

1/10/2014


Conclusions• KFA 53 requirements received. • Conceptual design for LIU-TDR delivered. • Functional Specification to be written until

December.• Resources estimate and Budget/Manpower

planning to be done.• Technical Specification to be delivered in mid

2015. • Delivery of KFA-53 magnet and generator as

foreseen in 2018.

1/10/2014


Outlook w.r.t lessons learned during LS1

• KFA53 project goes in parallel with many other consolidation and LIU projects.

• Injector restart after LS1 showed many unplanned events and subsequently unscheduled interventions (source sometimes outside ABT responsibility!).

• Also commissioning of renovated systems showed that time for correction of non-conformities was necessary.

• Staged approach of accelerator ramp up looks excellent in theory but for hardware sections it means that troubleshooting for already running CPS overlaps with PS/SPS commissioning whilst there is still installation work in the LHC ongoing. This has to be covered by the same manpower.

• With combined efforts it was manageable for LS1 but it will be a totally different challenge to deliver and commission several completely new (and additional) systems beside the usual start up business (and changing staff).
