Step 10 of building a @km3net Digital Optical Module (DOM) @_nikhef

In this episode we see the closing of a DOM. Assembly of a DOM is now ready and will be stored in a dark cabinet to be assembled later in the assembly together with 18 other DOMs into a Detector Unit (DU).

Click to see the real deal ➡️

This #PhotoOfTheWeek, we look at a mock-up of the @ATLASexperiment detector, assembled by Jan Brajer from the ATLAS Detector Operation group, in comparison with the real-size detector.

These images show a model of ATLAS composed of 400 parts, a present to an ATLAS technical coordinator, who retired earlier this year after almost a decade of work on the ATLAS detector.

The real deal sits on a cavern 100m below ground, one of two general-purpose detectors at the Large Hadron Collider (LHC). It investigates a wide range of #physics, from the #Higgs boson to particles that could make up #DarkMatter.

Step 9 of building a @km3net Digital Optical Module (DOM) @_nikhef
In this episode we see sealing of the top PMT-structure to the cooling mushroom and putting the highly transparent optical gel between the PMTs and hemisphere to permanently fixed the 31 PMTs in the hemisphere.

Morgen komt de 12e editie van Nikhef-magazine DIMENSIES uit! Op de cover onze KM3NeT-onderzoekers en technici met de Digital Optical Modules (DOM's) van de KM3NeT-neutrinodetector. Deze worden o.a. op Nikhef geproduceerd. @km3net

Step 8 of building a @km3net Digital Optical Module (DOM) @_nikhef
In this episode we see the pre-assembly of the PMTs (PhotoMultiplier Tubes) before we do functional tests to be sure everything works before the PMTs are finally fixed with optical gel.

Step 7 of building a @km3net Digital Optical Module (DOM) @_nikhef
In this episode we see the assembly of the bottom PMT-structure (3D printed in nylon) with 19😲PMTs (PhotoMultiplier Tubes).

The @CERN #ATLAS ITK ENDCAP is now placed on 12 vibration dampers at @_nikhef. Just before closing the insulated transport box (by mounting the 5 enormous plates by @hasenkamp) shock sensors are now being mounted on frame & ENDCAP.
Transported to @desy is close by 🚀

[NL-ix @nl_ix]

Last Friday we visited @_nikhef, a historic cornerstone of European Internet history and a vital hub in our network. As one of the places where the Internet in Europe took its first steps, Nikhef continues to play a critical role in enabling fast, secure, and reliable connections across the continent.

Thank you Nikhef on behalf of team NL-ix!

A huge insulated transport box (3x3x3.5m - 1800 kg) arrived @_nikhef for the transport of the @CERN #ATLAS ITK ENDCAP to @desy next week. The box is insulated all around on the inside with 8.5 cm thick vacuum insulation panels.

[Ivo van Vulpen @IvovanVulpen]

Great discussion with student from @UniLeiden's Science Communication & Society master track on investigating use of metaphors in our field by scientists, @_nikhef, @CERN, @ATLASexperiment & journalists. New world for @claranellist and me to discover as supervisors. More later!

Step 6 of building a @km3net Digital Optical Module (DOM) @_nikhef .
In this episode we see the assembly of 12 PMTs (PhotoMultiplier Tubes) in the top hemisphere PMT-structure. This plastic injection molded PMT-structure is developed in collaboration with @Windesheiminfo

[Marco Kraan @MarcoJKraan]

Step 5 of building a @km3net Digital Optical Module (DOM).
In this episode we see the pre-assembly of the fiber tray and the fusion splicing process of two optical fibers.
We follow the entire build at @_nikhef from 2 empty glass hemispheres to a complete detector.
