360 Degree Panoramic Photographs During the Long Shutdown 2 of the CERN Machines and Facilities
/ Birtwistle, Thomas (CERN) ; Ansel, Antoine (CERN) ; Bartolomé Jiménez, Sonia (CERN) ; Feral, Bruno (CERN) ; Lacerda, Gil (CERN) ; Perrot, Anne-Laure (CERN) ; Piñera Ovejero, Juan F (CERN)
Studies and preparation of activities are key to the success of short technical stops and longer shutdowns in CERN’s accelerator complex. The ’Panorama’ tool offers a virtual tour of our facilities, and thanks to integration with other CERN tools, further complementary information can be easily retrieved, including layout information, equipment detail, and a history of changes.

CERN Accelerators Topology Configuration: Facing the Next Long Shutdown

The Configuration and Layout (CL) team at CERN ensures that there is a clear and coherent representation of the status of the CERN underground facilities (about 60 km of equipment) and main accelerator projects at a given point in time. In view of the major equipment changes to be carried out during the extended end of year technical stop (EYETS), the next Long Shutdown (LS2), and to facilitate the associated preparatory work of multiple CERN groups, the CL team has developed an immersive visualisation tool, displaying 360 degree panoramic images of CERN underground facilities.

Polytech., Palaiseau (main)) ; Itow, Y (Nagoya U., Solar-Terrestrial Environ. Lab. ; KMI, Nagoya) et al.
The LHCf experiment is an unique dedicated experiment for measurement of very forward particle production relevant to cosmic-ray air shower developments. The LHCf measured the spectra for forward photons, neutral pions and neutrons at $\sqrt{s}$ = 7 TeV p–p collisions and the nuclear modification factor for forward neutral pions at $\sqrt{s}$ = 5 TeV p-Pb.

The LHCf experiment, optimized for the study of forward physics at LHC, completes its main physics program in this year 2015, with the proton-proton collisions at the energy of 13 TeV. LHCf gives important results on the study of neutral particles at extreme pseudo-rapidity, both for proton-proton and for proton-ion interactions. [...]

LHCf Experiment: Physics Results
/ Bongi, M (INFN, Florence ; Florence U.) ; Adriani, O (INFN, Florence ; Florence U.) ; Berti, E (INFN, Florence ; Florence U.) ; Bonechi, L (INFN, Florence) ; Castellini, G (INFN, Florence ; IFAC, Florence) ; D'Alessandro, R (INFN, Florence ; Florence U.) ; Del Prete, M (INFN, Florence ; Florence U.) ; Haguenauer, M (Ecole Polytechnique) ; Itow, Y (Nagoya U., ISEE ; KMI, Nagoya) ; Iwata, T (Waseda U.) et al.
LHCf is an experiment designed to study the forward emission of neutral particles produced in proton-proton and proton-nucleus collisions at the LHC. The detectors consists of a pair of electromagnetic sampling calorimeters installed on both sides of the ATLAS interaction point IP1 at a distance of 140 m, covering the pseudorapidity range from 8.4 to infinity.
