Introduction

• Philip Bambade (Laboratoire de l''Accelerateur Lineaire (LAL) (IN2P3) (LAL))

New measurements of CLIC honeycomb structure

• Benoit BOLZON (LAPP)

Resonance properties of honeycomb structure supported on floor. Coherence properties on floor and on table. Convolution of honeycomb structure transfer function with ATF floor measurement. Description of present support method and of dedicated supports sold by the manufacturer. Interim conclusion on relevance of honeycomb structure as FD support. Future program.

Further studies and possible scenario

• Andrea Jeremie (LAPP)

Studies with lumped mock weights on the FFTB supports. Studies with actual QD and QF when available. Preferred strategy with independent supports for FD and BSM. Time line.

General discussion Additional comments and/or suggestions following previous presentations. Plans for regular reviewing of progress and strategy within the normal ATF2 weekly meetings. Schedule for QD and QF reconfiguration with larger aperture. Is re-machining still to be considered ? Future reviewing of BSM rigid support and evaluation of its transfer function.
