Smashing The Atom: A Brief History Of Particle Accelerators

When it comes to building particle accelerators the credo has always been “bigger, badder, better”. While the Large Hadron Collider (LHC) with its 27 km circumference and €7.5 billion budget is still the largest and most expensive scientific instrument ever built, it’s physics program is slowly coming to an end. In 2027, it will receive the last major upgrade, dubbed the High-Luminosity LHC, which is expected to complete operations in 2038. This may seem like a long time ahead but the scientific community is already thinking about what comes next.
Recently, CERN released an update of the future European strategy for particle physics which includes the feasibility study for a 100 km large Future Circular Collider (FCC). Let’s take a short break and look back into the history of “atom smashers” and the scientific progress they brought along.

Crunching Giant Data From The Large Hadron Collider

Modern physics experiments are often complex, ambitious, and costly. The times where scientific progress could be made by conducting a small tabletop experiment in your lab are mostly over. Especially, in fields like astrophysics or particle physics, you need huge telescopes, expensive satellite missions, or giant colliders run by international collaborations with hundreds or thousands of participants. To drive this point home: the largest machine ever built by humankind is the Large Hadron Collider (LHC). You won’t be surprised to hear that even just managing the data it produces is a super-sized task.

Since its start in 2008, the LHC at CERN has received several upgrades to stay at the cutting edge of technology. Currently, the machine is in its second long shutdown and being prepared to restart in May 2021. One of the improvements of Run 3 will be to deliver particle collisions at a higher rate, quantified by the so-called luminosity. This enables experiments to gather more statistics and to better study rare processes. At the end of 2024, the LHC will be upgraded to the High-Luminosity LHC which will deliver an increased luminosity by up to a factor of 10 beyond the LHC’s original design value.

Currently, the major experiments ALICE, ATLAS, CMS, and LHCb are preparing themselves to cope with the expected data rates in the range of Terabytes per second. It is a perfect time to look into more detail at the data acquisition, storage, and analysis of modern high-energy physics experiments.

The Future Circular Collider: Can It Unlock Mysteries Of The Universe?

In the early 1990s, I was lucky enough to get some time on a 60 MeV linear accelerator as part of an undergraduate lab course. Having had this experience, I can feel for the scientists at CERN who have had to make do with their current 13 TeV accelerator, which only manages energies some 200,000 times larger. So, I read with great interest when they announced the publication of the initial design concept for the Future Circular Collider (FCC), which promises collisions nearly an order of magnitude more energetic. The plan, which has been in the  works since 2014, includes three proposals for accelerators which would succeed CERN’s current big iron, the LHC.

Want to know what’s on the horizon in high-energy physics?

Hackaday Links: December 18, 2016

You can fly a brick if it has offset mass and you can fly a microwave because it breaks the law of the conservation of momentum. A paper on the EM Drive was recently published by the Eagleworks team, and the results basically say, ‘if this works, it’s a terrible thruster that shouldn’t work’. Experts have weighed in, but now we might not have to wait for another test in the Eagleworks lab: China will fly an EM Drive on their space station. Will it work? Who knows.

The ESP32 is just now landing on workbenches around the globe, and already a few people are diving into promiscuous mode and WiFi packet injection.

The Large Hadron Collider is the most advanced piece of scientific apparatus ever built. It produces tons of data, and classifying this data is a challenge. The best pattern recognition unit is between your ears, so CERN is crowdsourcing the categorization of LHC data.

Holy crap this is cyberpunk. [SexyCyborg] created a makeup palette pen testing device thing out of a Rasberry Pi and a few bits and bobs sitting around in a parts drawer. The project is cool, but the photolog of the finished project is awesome. It’s exactly what you would use to break into the Weyland-Yutani database while evading government operatives on the rooftops of Kowloon Walled City before escaping via grappling hook shot into the belly of a spaceplane taking off.

The Mini NES is Nintendo’s most successful hardware offering since the N64. This tiny device, importantly packaged in a minified retro NES enclosure, is out of stock everywhere. That doesn’t matter because now there’s a mini Genesis. The cool kids had a Genesis. You want to be a cool kid, right? Mortal Kombat was better on the Genesis.

The Arduino (what once was two is again one) launched a new vowel-hating model: MKRZero. The narrow board is powered by USB or LiPo, centers around an Atmel SAMD21 Cortex-M0+ chip, and sports both an I2C breakout header and a microSD card slot. Just watch those levels as these pins are not 5v tolerant.

The American Association for the Advancement of Science is holding a Scientific Maker Exhibit during its annual meeting. This type of exhibit isn’t a poster or presentation — it’s just some table space and a chance to show off a 3D printed apparatus, a new type of sensor, equipment, or some other physical thing. Details in this PDF. This is actually cooler than it sounds, and a significant departure from the traditional poster or presentation found at every other scientific conference.

Did you know Hackaday has a retro edition made specifically for old computers connected to the Internet? That’s my baby, and it’s time for a refresh. If you have any feature requests you’d like to see, leave a note in the comments.

TIME’s Best Inventions Of 2008

tesla

Attempting to put our past behind us as quickly as possible, TIME has released what they feel are the best inventions of 2008. While there’s some pretty wishy-washy lab-only stuff on the list, we’re glad to see a lot of cool hardware made the cut. Some of our favorites are: The Tesla roadster proving electric cars can be fun. IBM breaking the petaflop barrier with LANL’s Roadrunner. The Large Hadron Collider for getting everyone scared about physics all over again. Have a look at the list for many other tech highlights from this year.

Large Hadron Collider Roundup

The Large Hadron Collider was a success and it didn’t destroy the world. We have to admit, we were a little bit worried about the possibility of generating black holes but were soothed by scientists’ reassurances that we would still exist, and this self-explanatory website. We’re also kind of hoping to build our own. PHD Comics visits CERN to learn all about the experiment. Xkcd prepares for the end times with a new friend. The curious can explore some amazing imagery of the LHC, and read about the best-and-worst-case scenarios, and what scientists are hoping for, or monitor progress via webcam. The celebratory will listen to appropriate music, consume inspired science fiction, and drink to the Large Hadron Collider and its success.

Hack A Day 2: Electric Boogaloo

Well, that was fun… no, not really, but we’re back from the dead like Steve Jobs. We’ve been getting DDoS’d since essentially the first day we originally came back. After killing a 1G connection, we decided to find a different solution. Since the world didn’t end this week, we brought the site back using WordPress.com as the new host. We now return to our regular blog shenanigans. Here’s to another four years of beta!
