75. Sector Test: Overview, Motivation and Scheduling

Mike Lamont (LFC)

26/01/2006, 14:00

An overview of and the motivation for the sector test are recalled. The essential components for the test are enumerated and the requisite preparation detailed. The scheduling of the preparatory steps, the test itself and recovery from the test. This is presented together with the potential impact and interaction with hardware commissioning and ongoing installation.

82. Proposed tests with beam

Brennan Goddard (CERN)

26/01/2006, 14:35

An overview of the proposed tests is presented, with time and beam load estimates. The necessary instrumentation and associated requirements on controls are discussed. The tests will include optics checks, aperture scans, instrumentation performance, magnet checks, injection protection, stability and quenches. For each test the methods are outlined, with the requirements on...

74. Magnet Quenches with Beam

Alexander Koschik (AB/ABP)

26/01/2006, 15:10

The motivation for quenching magnets during the sector test is revisited and presently assumed quench limits recalled. Which magnet (s) are planned to be used and the associated BLM layout and local aperture layout are detailed. The required beam intensity/emittance/angle to reach the quench limit in the coil is estimated and how this is to be achieved by steering beam into aperture. The...

78. Beam Instrumentation foreseen for the LHC sector test

Lars Jensen (AB/BDI)

26/01/2006, 16:00

The state of installation and preparedness of the large distributed system - BLMs and BPMs - is covered. The required controls infrastructure is described along with the proposed series of tests that will be performed to confirm readiness before the test it self. Other discrete instrumentation - BCT and BTV - are detailed and again plans for installation and testing are presented. The...

58. Magnets

Luca Bottura (AT/MTM)

26/01/2006, 16:30

The requirements of the sector test are described, this will cover: transfer functions, multipole errors, cycling prescription, and a de-Gauss cycle. The potential use of a field model is explored and the possible tests of this on the injection plateau following re-cycling.

59. Control Requirements

Robin Lauckner (AB/CO)

26/01/2006, 17:00

The sector test will provide an interesting milestone for the LHC control system. An overview of the infrastructure and technical systems, including the beam interlocks, that have to be in place for the test is given. The requirements on the high level software are detailed. Planning for the delivery of this software is outlined.Pre-testing of the control facilities will be vital and...
