Status of Hamburg moving beam pipe 1. Beam pipe • Best assembly K. Piotrzkowski FP 420 meeting, CERN, June'09 7

Status of Hamburg moving beam pipe 1. Beam pipe • Two pockets are now laser welded K. Piotrzkowski FP 420 meeting, CERN, June'09 8

Status of Hamburg moving beam pipe 1. Beam pipe • Good quality obtained: Preferred technique – electro-erosion + laser welding • 3 D metrology – next week K. Piotrzkowski FP 420 meeting, CERN, June'09 9

Status of Hamburg moving beam pipe 1. Beam pipe • • Two pockets are now laser welded – section ready for summer beam tests, but. . . RF screen: Copper or stainless steel? K. Piotrzkowski FP 420 meeting, CERN, June'09 10

Status of Hamburg moving beam pipe 2. Next steps • Copper coating at CERN? Now or later? • Bellows? • Dimensions of Si box (previous slide) – need to be defined/confirmed asap for next beam tests!! (NB. We do not work on any detector integration mechanics – this has to be done by somebody else, we just provide a gas-tight box) K. Piotrzkowski FP 420 meeting, CERN, June'09 11

Status of Hamburg moving beam pipe 2. Next steps • B. Florins left in November’ 09, on March 1 st Georg Nuessle have started with us – he is based at CERN and take part in moving pipe development • CERN led moving pipe design group is being set up by Detlef – work-package in preparation, with first goal moving pipes at 220/240 m for 2011 – we need support from ATLAS/CMS asap to start it! Should approach respective managements in July. • BTW: Most probably one will simplify design for this 1 st stage: single pocket and no moving BPMs? One station per arm? K.
