1 Sector Test – Preparation Layout in LSS7 Jan Uythoven (AB/BT) Thanks to Mike Lamont and the other ‘sector testers’
2
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 2 Sector Test: LSS7 Conditions and layout should be as close as possible to the final situation from injection to LSS7.R By definition this is not possible for LSS7.R as this is the end of the sector to be tested Beam 2 Beam Dump Shielding Dispersion Suppressor Long Straight Section IP7
3
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 3 What should not be installed in LSS7 D4 and everything towards the IP not installed or not required D3 may be installed, but will not see any beam Check interference with shielding behind dump No collimators installed (no TCP, TCHS, TCM, TCG) Q6 & DFBM should be installed Consists of 6 x MQTLH, not part of dispersion suppressor (up to Q8) Presently confirmed to be ready not installed DFBM
4
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 4 Installation of Beam Dump in LSS7 Temporary installation Beam dump same type as used for TI 8 tests But SPS type transport system attached to it, to avoid installation of fixings in the ceiling Positioned on temporary support (blocks) ‘Borrowed’ from TI 2 No additionally radiated equipment Beam dump in place in TI 8 (smaller tunnel) Additional shielding as used in TI 8 End of beam pipe
5
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 5 Position of temporary dump not installed Space for QRL return module Position dump at sufficient distance from QRL return module: - mechanical interference - radiation Q6 29 m
6
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 6 Beam Dump Area Transport and installation of beam dump and additional shielding Need to be integrated in LHC planning Path taken for the transport Time required for transport and installation (2 – 3 days) Possibly obstruct passage once installed Details of obstruction from drawing with dump in position Assume 4 weeks for installation, operation, cool down, removal Radiation issues Remnant radiation: will effect access conditions after tests Check with work planned in this area Need of radiation monitoring See talk of Helmut Vincke
7
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 7 Other additional equipment Additional BDI BCT half way between Q6 and beam dump: measure the intensities dumped on the TED Additional BDI NOT installed BLMs As there should be some already on Q6 BPM at Q6 will also indicate beam, besides the screen Radiation monitors near dump are foreseen BTV Standard BTV installed less than 1 m in front of Q6 Vacuum pipe between sector valve on Q6 up to the beam dump Proposed is 4 sections of about 7 m each Stops about half a meter before dump, standard AlTi window with CC protection against implosion The VADL installed on the left of Q6 includes an ion pump + pirani + penning gauge for the part left of the sector valve No additional vacuum pumping or instrumentation required
8
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 8 Access & Ventilation Additional access door Temporary access door about 800 m in the arc 7 – 6 Access to part of sector 6 – 7 will not be possible At least one day before the test (closing the zone) during the beam tests 2 – 3 days following the tests See talk Pierre Ninin on the Temporary Access System Collimation ventilation doors will not be installed For handling radioactive air produced at the collimators Not an issue for the sector tests (no collimators) Don’t want the doors, or chicanes for final layout, to ease transport of equipment
9
Jan Uythoven, AB/BTChamonix@Divonne 2006, Layout in LSS7 Page 9 Conclusions Layout in LSS7 as will be used for the sector test will be identical to the nominal situation up to and including Q6.R7 Only additional equipment foreseen: Beam dump: TED from TI 2 and additional shielding BCT in front of TED Vacuum chamber between Q6 and TED To be studied in more detail Transport of TED Effect of TED installation and radiation issues on the general LHC planning Detailed layout drawing for sector test set-up in LSS7 to be made in the coming months
