Chamonix XV - Sector Test

Session A - Beam

Chairman: Mike Lamont, Scientific Secretary: Verena Kain


Overview, motivation & scheduling - 20 minutes

Mike Lamont - confirmed

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.


Proposed tests with beam - 25 minutes

Brennan Goddard - confirmed

An overview of proposed tests, time & load estimates is presented. The necessary instrumentation commissioning  and associated requirements on controls are discussed. The tests will include optics checks, aperture scans, magnet checks, stability and quenches. For each test the requirements on instrumentation & controls are highlighted. The demands on the machine protection system are given.
 


Magnet Quenches with Beam - 15 minutes

Alex Koschik - confirmed

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 quench limit in coil is estimated and how this is to be achieved by  steering beam into aperture - how and where - and the maximum angles is estimated. The present state of affairs vis a vis  FLUKA simulations is mentioned plus what still needs to be done.
Other requirements (extra instruments, controls, applications, logging, RP, ...) are briefly enumerated.


Beam Instrumentation - 20 minutes

Lars Jensen - confirmed

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 need and plans for other systems, BST for example,  is also mentioned.

The proposed acquisition modes during the test are described along with desired measurements to assess instrumentation performance.


Magnets - 20 minutes

Luca Bottura - confirmed

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.


Controls  inc. beam interlocks - 20 minutes

Robin Lauckner - confirmed

An overview of the systems that have to be available for the sector test is given. The associated infrastructure and requirements on this are described. Testing will be vital before the sector test and description of the test procedures and their scheduling are given.
