DCES in CERN Bulletin
The article “Of data and dust” was published in the CERN
Bulletin.
This article gives a refreshing overview of the project, why and how it
was developed it in the CERN IT department.

White Rabbit PTP Core v3.0 release is out
We are happy to announce the new v3.0 stable release of the WR PTP Core. It comes with new features and stability improvements. As usual, you can find all the links to download the binaries, sources and manuals on our release wiki page.

15-12-15: Pickin’ up good vibrations in CERN Bulletin
In preparation for the civil engineering work on the HL-LHC at CERN,
vibration measurements were carried out at the LHC’s Point 1 last month.
These measurements help evaluate how civil engineering work could impact
the beam, and will provide crucial details about the site’s geological
make-up before construction begins.
…
Geophone sensors to measure vibrations in the ground were placed around
the vibration sources at the surface, linked to the underground
geophones using the LHC “White Rabbit” synchronisation network. This
allowed the team to look at the effects of the vibrations at the same
time.

07-12-2015: WR in deep sea: 3500m depth, 100km off coast
On 3 December 2015 a first line with 18 Digital Optical
Modules, each one containing a
White Rabbit PTP Core -
WRPC, was
deployed successfully and communicated over 100 Km of fiber with the
shore station.
This installation is 100 km into the sea off the coast of Italy at 3500
meter depth and must be the weirdest and harshest place to install WR
nodes.
This is a first step in the installation of
KM3NET, a European deep-sea research
infrastructure hosting a neutrino telescope.

12-11-2015: WR used in seismic measurements
CERN is trying to decide whether they can start Civil Engineering for the Hi-Luminosity project while the beam is on. The alignment of magnets is very delicate in the LHC and very slight variations thereof can produce beam instabilities. This is important because the potential impact on the overall schedule is big. The CERN EN-MME group has teamed up with the city of Geneva to have a shaker truck shake the ground and feel the impact down in the pit at point 1 (ATLAS), so as to have an indication of what to expect during real civil engineering work. The excitation and the sensors are separated by a few hundred meters, and they need to be synchronized, which is why they requested a WR link.
