Outgassing measurement of an LHC collimator and estimation for the NEG performances / Kamiya, Junichiro (JAEA, Ibaraki ; CERN) ; Baglin, V (CERN) ; Jimenez, J M (CERN) ; Bregliozzi, G (CERN)
The outgassing rate of the collimators in the Large Hadron Collider (LHC) at CERN has an important role for the life-time of the Non-Evaporable Getter (NEC), and an accurate analysis allows the definition of future activities, like NEC vacuum activation. For these reasons, both, total outgassing rate and gas composition of a secondary collimator have been measured in the laboratory. [...]

Assessment of New Components to be integrated in the LHC Room Temperature Vacuum System / Bregliozzi, G (CERN) ; Baglin, V (CERN) ; Chiggiato, P (CERN)
Integration of new equipment in the long straight sections (LSS) of the LHC must be compatible with the TiZrV non-evaporable getter thin film that coats most of the 6-km-long room-temperature beam pipes. This paper focus on two innovative accelerator devices to be installed in the LSS during the long shutdown 1 (LS1): the beam gas vertex (BGV) and a beam bending experiment using a crystal collimator (LUA9). [...]

Measurement of NEG Coating Performance Variation in the LHC after the First Long Shutdown / Bencini, Vittorio (CERN) ; Baglin, Vincent (CERN) ; Bregliozzi, Giuseppe (CERN) ; Chiggiato, Paolo (CERN) ; Kersevan, Roberto (CERN) ; Yin Vallgren, Christina (CERN)
During the Long Shutdown 1 (LS1) of the Large Hadron Collider, 90% of the Non-Evaporable Getter (NEG) coated beam pipes in the Long Straight Sections (LSS) were vented to undertake the planned upgrade and consolidation programmes. After each intervention, an additional bake-out and NEG activation were performed to reach the vacuum requirements. [...]

Bake-Out Mobile Controls for Large Vacuum Systems / Blanchard, S (CERN) ; Bellorini, F (CERN) ; Gomes, P (CERN) ; Pereira, H (CERN) ; Kopylov, L (Serpukhov, IHEP) ; Merker, S (Serpukhov, IHEP) ; Mikheev, M (Serpukhov, IHEP)
Large vacuum systems at CERN (Large Hadron Collider - LHC, Low Energy Ion Rings - LEIR...) require bake-out to achieve ultra-high vacuum specifications. The bake-out cycle is used to decrease the outgassing rate of the vacuum vessel and to activate the Non-Evaporable Getter (NEG) thin film [...]

Achievement and Evaluation of the Beam Vacuum Performance of the LHC Long Straight Sections / Bregliozzi, G (CERN) ; Baglin, V (CERN) ; Blanchard, S (CERN) ; Hansen, J (CERN) ; Jiménez, J M (CERN) ; Weiss, K (CERN)
The bake-out and activation of the TiZrV NEG coatings of the 6 km Long Straight Sections (LSS) of the Large Hadron Collider (LHC) is in its final step. After the bakeout and the NEG activation, the average ultimate pressure, over more than one hundred vacuum sectors, is below 10^-10 Pa [...]

LHC Experimental Beam Pipe Upgrade during LS1 / Lanza, G (CERN) ; Bregliozzi, G (CERN) ; Baglin, V (CERN) ; Chiggiato, P (CERN)
The LHC experimental beam pipes are being improved during the ongoing Long Shutdown 1 (LS1). Several vacuum chambers have been tested and validated before their installation inside the detectors. [...]

Saturation behaviour of the LHC NEG coated beam pipes / Porcelli, T (CERN) ; Bregliozzi, G (CERN) ; Lanza, G (CERN) ; Baglin, V (CERN) ; Jimenez, J M (CERN)
In the CERN Large Hadron Collider (LHC), about 6 km of the UHV beam pipe are at room temperature and serve as experimental or utility insertions. TiZrV non-evaporable getter (NEG) coating is used to maintain the design pressure during beam operation. [...]

Synchrotron radiation-induced desorption from a NEG-coated vacuum chamber [of ESRF beamline] / Chiggiato, P ; Kersevan, R
When the whole inner surface of a vacuum chamber is coated with a non-evaporable getter film, very low static and dynamic pressures are expected after activation. In an accelerator environment this could result in a longer beam lifetime, in a lower risk of pressure bumps, and in a lower level of bremsstrahlung radiation due to the beam-gas interactions. [...]
