FP7: EuCARD after a year of preparation… A.Jeremie

A bit of history 2006: Letters of intent October 2006: working groups getting better organised (LHC, SC, Novel tech.) Spring/Summer 2007: sub-groups defining proposals=> lots of meetings September 2007: ESGARD meeting at CERN=>proposals selected Autumn 2007: Writing of proposal and lots of cost reduction!! Painful! And…

Budget EU request = 30% of total budget

Task 3: Linac & FF stabilisation It is planned in this project to study the effectiveness of stabilisation equipment (such as seismic sensors, actuators, interferometers etc…) in a real accelerator environment. The equipment will be implemented at a CLIC quadrupole module inside the CTF3 facility, in the first stage with a quadrupole mock-up. In addition it is planned to use a CLIC standard module for comparing the vibration measurements with a laser interferometer (which can also serve as an alignment device) and the seismic sensors. The compatibility of these stabilisation devices with the alignment system that will be used in CLIC will be checked. A dedicated FF test stand will be built with a support and magnet prototype where the stabilisation will be developed. Furthermore, the stabilisation procedures will be simulated to ensure a better understanding of the beam-based feedback, stabilisation and the alignment. This will be tested on different accelerator facilities such as ATF2, CTF3 in preparation of ILC and CLIC.

Sub-task 1: CLIC quadrupole module CERN together with LAPP aims at demonstrating 1 nm quadrupole stability for the CLIC main linac quadrupole. – stabilisation feedback performance in different locations – 1 nm stability of the main linac quadrupoles in an accelerator environment – Test and evaluate Inertial sensors for accelerator environment – study vibration isolation for the main beam quadrupole – CERN will study the design and construction of main linac prototype magnet. The interferometric measurement system, developed in UOXF- DL, will be used to cross check results CERN aims at testing the compatibility between the repositioning system and the stabilization system in the real environment of the two beam test stand.

Sub-task 2: Final Focus Test stand LAPP together with CERN aims at exploring the potential to achieve 0.1nm stability scale for the final doublet quadrupoles > few Hz – design, simulation, construction and installation of the support – feedback design depending strongly on the final doublet support chosen. – LAPP will adapt feedback software to new configuration and boundary conditions and continue work to reduce costs. Oxford aims at studying the design, construction and deployment of an interferometric system – measure the motion between test magnet/girder and floor. – Installation of interferometric system with maximum resolution – correlate results with measurements done by inertial sensors. UOXF-DL will contribute to the Development of optimized low- emittance beam transport and feedback for ILC and CLIC – completing an ILC prototype ATF2 intra-train and pulse-pulse FB and FF – study the simulation of the global luminosity performance of ILC and CLIC.
