First beam splashes at the LHC
Premières éclaboussures de faisceau dans le LHC
/ CERN Bulletin
After a two-year shutdown, the first beams of Run 2 circulated in the LHC last Sunday. On Tuesday, the LHC operators performed dedicated runs to allow some of the experiments to record their first signals coming from particles splashed out when the circulating beams hit the collimators [...]

Upcycling CERN Exhibitions
Une nouvelle vie pour les objets des expositions du CERN
/ Katarina Anthony
Summer is coming - and with it, a new Microcosm exhibition showcasing CERN (see here). But while the new exhibit is preparing to enchant visitors, many have been asking about the site's former content [...]

LHC Report: Now it’s full speed ahead (still with probe beam)
Dernières nouvelles du LHC : en avant toute ! (avec des faisceaux d’essai)
/ Mike Lamont
Since the last report, the commissioning with beam was delayed after a short to ground appeared in the cold mass of the main dipole chain in sector 3-4. After a remarkable team effort coordinated by the Machine Protection group, a procedure to burn away the small piece of metallic debris that was causing the earth fault was conceived, prototyped, tested and deployed [...]

Important milestones for the LHC and for integrity
Une semaine importante pour le LHC et pour l’intégrité
/
The major news this week is, of course, the start of LHC Run 2. Things went smoothly once the short circuit to ground in sector 3-4 had been resolved on 31 March, and by the time of the morning meeting at the CERN Control Centre on Easter Sunday, everything was ready to thread a beam around the machine [...]

TOTEM: Discoveries may go “forward” at the LHC
TOTEM : en avant pour de nouvelles découvertes
/ TOTEM Collaboration
After two very intense years of activity during which the TOTEM apparatus has gone through an extensive upgrade programme, the collaboration is now ready to explore the new territories in forward physics that will open at 13 TeV.   One vertical TOTEM Roman Pot and a tilted one, in the LHC tunnel. [...]

Did you miss the eclipse?
Vous avez manqué l'éclipse ?
/ CERN Bulletin
Not wanting to miss a moment of the beautiful celestial dance that played out on Friday, 20 March, Jens Roder of CERN’s PH group took to the Jura mountains, where he got several shots of the event. Here are a selection of his photos, which he was kind enough to share with the Bulletin and its readers [...]

Intelum project: tackling the calorimetry challenge for future high-energy colliders
Projet Intelum : relever le défi de la calorimétrie pour les futurs collisionneurs de haute énergie
/ CERN Bulletin
Intelum is one of the CERN-coordinated projects funded under H2020. It aims to develop low-cost, radiation-hard scintillating and Cherenkov crystal and glass fibres for the next generation of calorimeter detectors for future high-energy experiments [...]

Tracking the LHC halo
Suivre le halo du LHC à la trace
/ Antonella Del Rosso
In the LHC, beams of 25-ns-spaced proton bunches travel at almost the speed of light and pass through many different devices installed along the ring that monitor their properties. During their whirling motion, beam particles might interact with the collimation instrumentation or with residual gas in the vacuum chambers and this creates the beam halo – an annoying source of background for the physics data [...]

MoEDAL: Passive but no less active
MoEDAL : passif, mais néanmoins très actif !
/ MoEDAL Collaboration
Relying almost completely on passive detectors, MoEDAL is a pioneering experiment designed to search for highly ionising avatars of new physics, such as magnetic monopoles or massive (pseudo-)stable charged particles. The first test detectors were deployed at LHC Point 8 in 2012 and analysed in 2013, and the full MoEDAL detector was installed in the winter of 2014 to start data-taking during Run 2 this year [...]
