Field Quality Measurements in the FNAL Twin-Aperture 11 T Dipole for LHC Upgrades / Strauss, T (Fermilab) ; Apollinari, G (Fermilab) ; Barzi, E (Fermilab) ; Chlachidze, G (Fermilab) ; Di Marco, J (Fermilab) ; Nobrega, F (Fermilab) ; Novitski, I (Fermilab) ; Stoynev, S (Fermilab) ; Turrioni, D (Fermilab) ; Velev, G (Fermilab) et al.
FNAL and CERN are developing an 11 T Nb3Sn dipole suitable for installation in the LHC to provide room for additional collimators. Two 1 m long collared coils previously tested at FNAL in single-aperture dipole configuration were assembled into the twin-aperture configuration and tested including magnet quench performance and field quality.

Beam test performance of the APV5 chip / de Fez-Laso, M D M (Imperial Coll., London) ; Bonaccorso, C (Imperial Coll., London) ; Gill, K (Imperial Coll., London) ; Hall, G (Imperial Coll., London) ; Iles, G (Imperial Coll., London) ; MacEvoy, B (Imperial Coll., London) ; Millmore, M (Imperial Coll., London) ; Potts, A (Imperial Coll., London) ; Raymond, M (Imperial Coll., London) ; French, M (Rutherford) et al.
The performance of the latest prototype of the radiation hard front end chip to be used by the CMS collaboration for analogue readout of the microstrip tracker has been evaluated with a silicon microstrip detector in a beam at CERN. The circuit, developed by the RD20 collaboration, consists of 128 channels of amplifier, pipeline memory, analogue signal processor and a serial multiplexer. [...]

The ATLAS Intensity upgrade: Project overview and online operating experience / Pardo, Richard (Argonne) ; Barcikowski, Albert (Argonne) ; Conway, Zachary (Argonne) ; Dickerson, Clayton (Argonne) ; Hendricks, Matthew (Argonne) ; Kelly, Michael (Argonne) ; Kim, Sang-Hoon (Argonne) ; Luo, Yong (Argonne) ; MacDonald, Stephen (Argonne) ; Mustapha, Brahim (Argonne) et al.
ATLAS, the world's first accelerator to use RF superconductivity for ion acceleration, has undergone a major facility upgrade with the goals of significantly increased stable-beam current for experiments and improved transmission for all beams. The dominant components of the upgrade are a) new CW-RFQ to replace the first three low β resonators, b) a new cryostat of seven β=0.077 quarter-wave resonators demonstrating world-record accelerating fields, c) an improved cryogenics system, and d) the retirement of the original tandem injector.

Integrating the TRACK beam simulation code to improve ATLAS operations / Dickerson, Clayton (Argonne) ; Mustapha, Brahim (Argonne) ; Peters, Christopher (Argonne)
At the Argonne Tandem Linear Accelerator System (ATLAS) we are integrating TRACK, three dimensional particle tracking software that numerically integrates the equations of motion, into the accelerator control system. ATLAS delivers a variety of ions (1 - 238 AMU) at various energies (1 - 15 MeV/u) to multiple targets. [...]

Status and operation of the ATLAS superconducting accelerator / Hendricks, Matthew (Argonne) ; Krupa, Anthony (Argonne) ; Pardo, Richard (Argonne)
ATLAS (the Argonne Tandem Linac Accelerator System) is a super conducting heavy ion accelerator which can accelerate nearly all stable, and some unstable, isotopes between protons and uranium with a charge to mass range of 1/1 to 1/7. The maximum energy ranges of these accelerated ions are 7-17 MeV per nucleon with intensities ranging from a few thousand ions/second to microampere currents. [...]
