soldering of multistrand wire connection under binoculary microscope

Ronaldus Suykerbuyk
For magnetic measurements special measurement coils are needed. This footage shows the steps to follow in order to solder connectors on a multi strand wire that is part of the measurment coil. Since the connectors are very tiny. The work is executed under a binoculary microscope.
The different steps:

00:00:00 cutting and separation ther wires and putting them in place on the connector.
00:01:40 tacking of the wires with very thin solder
00:02:14 final...

AMS EVA Highlights

This video is a documentary about the winning teams of BL4S 2019 at DESY.

A new life for AMS

Noemi Caraban Gonzalez & Paola Catapano
Relive the incredible story of four complex spacewalks to replace the entire cooling system of the Alpha Magnetic Spectrometer, AMS, a unique cosmic-ray detector, assembled at CERN. With ESA astronaut Luca Parmitano returning to Earth on 6 February, AMS scientists based at the control centre at CERN describe the nail-biting finale of the spacewalk series.

Vacuum Anim [inside a beam pipe]

Daniel Dominguez
Here is a cross-section of an LHC dipole magnet.
In the middle are the beam pipes, through the centre of which run the beams, one travelling inward and the other outward. Since the beams must run in vacuum so that their energy is not wasted in interactions with spurious molecules along the way, the air needs to be pumped out.
The pumping takes place in several stages, in parallel with the decrease in the temperature,...

Vacuum LHC all [vacuum amount]

Daniel Dominguez
Since the LHC is the largest accelerator in the world, it also has the largest vacuum system in the world.
A vacuum is needed so that the protons can travel through the beam pipes without losing energy along the way.
Each of the two LHC beam pipes is 27 km long, but the total length of all the vacuum pipes inside the LHC is 104 km: 54 km of ultra-high-vacuum (UHV) beam pipe lines, plus...

Bunches formation 2x2 [PS]

Daniel Dominguez
When they have been accelerated, the particle bunches are split into two halves twice more, before being injected into the SPS.

Après avoir été accélérés, les paquets de particules sont encore divisés deux fois en deux, puis ils sont injectés dans le SPS.

Bunches formation x3 [PS]

Daniel Dominguez
In the PS, each bunch is initially split into three smaller ones, which are then split again into two even smaller ones (not shown in this animation).

Dans le PS, chaque paquet est d’abord divisé en trois paquets plus petits, et chacun de ces paquets est ensuite à nouveau divisé en deux paquets encore plus petits (non visibles dans cette animation).

Bunches formation [PS]

Daniel Dominguez
Particles are injected into the LHC in small bunches. The process starts in the Proton Synchrotron Booster (PSB), which is made up of four superimposed synchrotron rings that receive beams of protons at an energy of 50 MeV from the linear accelerator Linac2, split them into bunches and accelerate them to 1.4 GeV for injection into the Proton Synchrotron (PS). In the PS, the proton bunches are split again and accelerated to an energy of...

Electricity Shutdown

Daniel Dominguez
In the event of a power cut and electricity shutdown, the 400 kV network from France is switched off, followed by the 66 kV and 18 kV networks.
Then the 130 kV back-up supply from Switzerland is used to reconnect all CERN’s general services, using the 18 kV network.

En cas de coupure de courant et d'arrêt de l’alimentation en électricité, le réseau 400 kV alimenté depuis la France est arrêté, puis les réseaux...

Electricity Running

Daniel Dominguez
The electricity running through the CERN sites is monitored in the CCC (CERN Control Centre). The island dedicated to this is the same one that controls the technical instrumentation for the cryogenics system. CERN receives its electricity via two very-high-voltage (400 kV) power lines connected to the French national grid at the Bois-Tollot substation near the Prévessin site.
An emergency back-up supply (130 kV) is provided by the Swiss grid and can be used if,...


Daniel Dominguez
CERN’s main control room (CCC, for CERN Control Centre) is located in Prévessin (France) and is divided into four main sectors or “islands”, each controlling a specific part of the accelerator chain.
Starting from the north-west (upper left) quadrant and running anti-clockwise, the first three are dedicated to controlling: the PS (Proton Synchrotron) and the booster, which are both located in Meyrin (solid yellow line on the animation); the SPS (Super Proton Synchrotron), indicated by...

*Video temporary replaced with a short clip*

Maria Barberan Marin & Miran Domajnko
On 9 January 2020, three groups of ATS-DO members guided by Pieter Mattelaer and Milton Morais from SMB had the opportunity to descend approximately 60 meters underground to visit the new HL-LHC galleries located at Point 1 and celebrate the New Year.

Estel Perez Codina for WomenInScience campaign

Noemi Caraban Gonzalez
Estel Perez Codina is an engineer. She is working on the sTGC detectors for the New Small Wheel for ATLAS. In order to fully exploit the HL-LHC luminosities, the innermost stations, the so-called Small Wheels (SW), of the ATLAS Muon Spectrometer need to be replaced, by two new detector assemblies called New Small Wheels (NSW).
