That's one more achievement that basic science research can result into.

Also in that issue there is an article about SESAME, a cooperative effort between Arab states, Iran and Israel to build a synchrotron light source in Jordan. Its scientific director is an Italian,Giorgio Paolucci, who comes from the Elettra Synchrotron near Trieste. Elettra is also providing equipment to SESAME.

Thanks for the update links Julie, but it does worry me a little to read this bit

The annual year-end technical stop provides an opportunity to carry out maintenance work on equipment and repair any damage as well as to upgrade the machines for the upcoming runs

Does that mean that the whole set-up is operating on a knife edge of stability, and was nowhere near complete when first installed? Yes it is at the leading edge of particle physics research, so I guess that is the price we pay.


They're working with the basic elements of life, so my guess is yes..

Every new particle accelerator, every new telescope such as JWST is always a prototype. There is no assembly line of accelerators and telescopes. I've read on the latest "Nature Physics" issue of February 2 what is inside the Lisa Pathfinder which is now at Lagrange point one and is being checked before starting physical observations. There are two masses in free fall at 38 cm distance which send laser beams to each other to measure the relative distance which might be altered by a passing gravitational wave. This is only a "proof of concept" experiment, in the eLISA configuration they would be aboard three spacecrafts in a triangle, with each side a million km long.They are testing it to prove that the idea is sound before spending millions of euros/dollars on the spacecrafts and their launchers. Lisa Pathfinder was launched by a mostly Italian Vega launcher from the ESA Kourou base. This proved the reliability of Vega and now eleven are in order, giving work to Italian and French industries.

Hints of a mysterious new particle at the world's largest particle accelerator just got a little stronger.

Evidence for fifth fundamental force grows: Latest LHC results back up existence of mystery particle that doesn't fit with laws of physics

Three months ago, physicists at the world's largest particle accelerator found the first signs of a particle heavier than the Higgs boson.

Now, hints of this mysterious new particle at the Large Hadron Collider (LHC) has just got more convincing.

While it falls short of the accuracy needed to be able to announce a discovery, it does make the reading more statistically significant – and that has got scientists excited.

Unexplained by current models, the particle's existence might lead to the discovery of a whole new set of particles and possibly even a fifth fundamental force.

At La Thuile (beautiful skiing place) CMS has upped its Sigma on the 750 GeV bump from 1.2 to 1.6 while Atlas has not changed. A Sigma of 5 is needed to confirm a new particle.

A small mammal, a beech marten, has disabled the LHC by biting through a power cable, killing itself. The LHC cooling system was disabled and will be restarted in mid May.

Update:

In Theory: Which came first…?

“I’m interested in physics theories beyond the Standard Model that can be tested. If I’ve got an idea, I want it to be used to interpret data. I don’t like speculating just for the sake of it” – John Ellis of King’s College London, who has worked at CERN since 1973.


“It’s a bit like the chicken and the egg”, smiles Christophe. But neither theorists nor experimentalists claim to be either the egg or the chicken (not that we really know which came first!). Each relies on the other’s knowledge to advance.

Having built and calibrated a bubble chamber for IAEA and solved a problem in theoretical physics using Lie algebras, I can claim to be both an experimental physicist and a theoretical physicist. Then the theorists took me for an experimentalist and the experimentalists took me for a theorist, so I was not offered any chance to work at the University of Trieste.
But I am running both CERN projects including CMS-dev@home and General Relativity projects from Einstein@home. I succeeded in installing a Nvidia graphic board in my Windows 10 PC running Einstein@home and a AMD/ATI graphic board in my main Linux host to run SETI@home and SETI Beta.

Picturing Particles

Visualising collisions in the ATLAS experiment


Spring is now in full bloom at the ATLAS experiment which recorded the year’s first collisions for physics on Monday, 9 May. Event displays from these collisions were immediately streaming on the ATLAS live website, with some shared across social media platforms.

The ATLAS collaboration use two types of visualisation software: VP1 and Atlantis. Both were specifically developed for the ATLAS experiment to analyse data directly and convert them into graphical objects. Each software has a specific area of expertise.

I am running Atlas@home on my Windows 10 PC with lot of memory. Each task needs 4 GB RAM and I can run concurrently 4 tasks on the 4 cores. Other CERN projects such as vLHC@home and vLHCathome-dev limit the number of concurrent tasks to 2 and one to avoid overloading PCs with small memories, but I have a 24 GB RAM which could bear the brunt.
