A.Jeremie, B.Bolzon, N.Geffroy Stable support for FD A.Jeremie, B.Bolzon, N.Geffroy Andrea JEREMIE

Outline Measurements on table Work done by G. Durand with drawings Discussion on table length Andrea JEREMIE

Measurements on table (since ATF2 meeting in Hamburg) Andrea JEREMIE

Set-up Empty table on four supports FFTB Movers just put on table, not fixed (~162kg) Measurements on FFTB movers No mass yet Guralp seismometer and Endevco accelerometer one each on the floor and on the table (or mover) Andrea JEREMIE

NI PCI-6052 Multifunction DAQ State of the art inertial sensors B.Bolzon NI PCI-6052 Multifunction DAQ Fast card Low noise card Compatible Matlab/Simulink (Softwares used for the algorithm) nm stabilisation equipment exists Andrea JEREMIE

Transfer function on table Empty table With movers Main peak slightly above 50Hz Andrea JEREMIE

Amplitude spectral density on ATF2 floor Ground motion measurements done on ATF floor by KEK colleagues Empty table With movers Andrea JEREMIE

Transfer function on mover Main peak still around 50Hz, but lots of additional peaks Andrea JEREMIE

Amplitude spectral density on mover Andrea JEREMIE

10nm 0.2 Andrea JEREMIE

Relative motion between table and floor at ATF Ring Integrated Root Mean Square of relative motion at ATF Ring: B.Bolzon No eigenfrequencies  Integrated RM of 4.5nm: due to supports not fixed to the floor and to the table Eigenfrequency bandwidth  Integrated RM of 5.0nm: Almost due to the first eigenfrequency Integrated RMS of relative motion with masses of 1400Kg: - From 0.17Hz to 100Hz: 6.7nm  Above ATF2 tolerances (6nm)!! - From 10Hz to 100Hz (first eigenfrequency bandwidth): 5.0nm Tight Andrea JEREMIE

Near future work Measurements with weights Finalise how mover is fixed on table and measure Andrea JEREMIE

Work done by G. Durand with drawings Andrea JEREMIE

Complete system for QC3 magnet (QD0 and QF1) Andrea JEREMIE

Complete system for QC3 magnet (QD0 and QF1) Larger magnet with shimming and LVDTs can still fit if some extra holes are done Andrea JEREMIE

T-plate New T-plate (need two large movers, but only one available, so transformed one small mover in large mover by doing a new T-plate) unchanged New T-plate can accommodate larger magnet (shimming) Andrea JEREMIE

“old” hand drawing New computer drawing Andrea JEREMIE

Discussion on table length Andrea JEREMIE

Notice that in this drawing the magnets are not always at same position on the mover Andrea JEREMIE

From Marc Woodley’s presentation on July 18 FF: MS2FF and Final Doublet QC3 180 180 MS FFTB 2.13 S3.00 SBPM SBPM 100 100 76.2 370 200 450.1 MS2FF SF1FF SD0FF QF1FF QD0FF scale: 6 inches (drawing) = 1 meter (beamline) Andrea JEREMIE

Marc Woodley’s answer to the design distances Hi Andrea, In ATF2v3.7Layout.ppt, the dashed lines around magnets represent the approximate extent of the coils; the lengths quoted for the magnets are the core lengths (not the effective lengths). The center-to-center separations of the magnets are what defines the layout: QD2AFF -> SF1FF : 4875 mm center-to-center SF1FF -> QF1FF : 575 mm center-to-center QF1FF -> SD0FF : 790 mm center-to-center SD0FF -> QD0FF : 575 mm center-to-center QD0FF -> IP : 1225 mm center-to-IP -Mark Andrea JEREMIE

! 10cm too short! QD0 SD0 QF1 SF1 245 310 245+575+790+575+310= 2495 Magnet center to center distances 2400 10cm too short! Andrea JEREMIE

“Free” first eigenfrequency (TMC value) 230Hz 185Hz Table length mm 2400 3000 Price € 15240 16500 delivery 12 weeks “Free” first eigenfrequency (TMC value) 230Hz 185Hz Simulated Four feet empty eigenfrequency 56Hz Simulated Four feet 1400kg eigenfrequency 26Hz Simulated totally fixed empty eigenfrequency 526Hz 629Hz Simulated totally fixed 1400Kg eigenfrequency 132Hz Andrea JEREMIE

Last words Current configuration leads to a table that is 10cm too short: Do we change configuration to fit on the table? Do we change the table (3000)? But does the layout allow this? Do we ignore the 10cm? Concrete block can be made to any dimension whereas the table has fixed constraints (length, height, hole configuration…)=> need to adapt Andrea JEREMIE
