How to build your own particle detector

Make a cloud chamber and watch fundamental particles zip through your living room. Image: Sandbox Studio

The scale of the detectors at the Large Hadron Collider is almost incomprehensible. They weigh thousands of tons, contain millions of detecting elements and support a research program for an international community of thousands of scientists.

But particle detectors aren't always so complicated. In fact, some particle detectors are so simple that you can make (and operate) them in your own home.

The Continuously Sensitive Diffusion Cloud Chamber is one such detector. Originally developed at UC Berkeley in 1938, this type of detector uses evaporated alcohol to make a 'cloud' that is extremely sensitive to passing particles.

Cosmic rays are particles that are constantly crashing into the Earth from space. When they hit Earth's atmosphere, they release a shower of less massive particles, many of which invisibly rain down to us.

When a cosmic ray zips through a cloud, it creates ghostly particle tracks that are visible to the naked eye.

Building a cloud chamber is easy and requires only a few simple materials and steps:

In Brief

Missed the Lab-Corps meeting? It's not too late

The Lab-Corps pilot provides Fermilab with the opportunity to commercialize new applications of accelerator technologies developed in pursuit of science to the important energy and environmental needs of our nation. If you missed the overview meeting at Fermilab, you can view a recording of a similar session that was held at Argonne. If you have an idea or invention that can be applied to create clean-energy solutions or would like more information, contact Cherri Schmidt.

Death

In memoriam: Herman J. Stredde

Herman Stredde, who worked as a mechanical engineer at Fermilab from 1969 until his retirement in 1995, passed away on Jan. 22 from complications due to Parkinson's disease.

The funeral mass will be held on Saturday, Jan. 31, at 10:30 A.M. at Holy Angels Church in Aurora.

Water Street Studios' first solo show explores ‘self’ through science

From Dowtown Auroran, Jan. 25, 2015

Meghan Moe Beitiks giddily explained neutrinos to three small boys on Saturday night at Water Street Studios where the artist opened her solo show, “Observations of Final States in Interactions.” The boys shared Beitiks excitement for a few minutes before quickly getting distracted; the idea of subatomic particles is a heady one.

The show, the gallery’s first solo exhibit, is a lot to take in at first glance. Chalk drawings of equations on painted doors, windows and desks, projections of changing images on the walls, and a long, paper graph “hitmap” all absorb the senses. All the work not only explores identity and self, but it opens up communication between the layperson and the physicist, who is studying and being studied.

ELBNF is born

Joe Lykken

At approximately 6:15 p.m. CST on January 22, 2015, the largest and most ambitious experimental collaboration for neutrino science was born.

It was inspired by a confluence of scientific mysteries and technological advances, engendered by the P5 report and the European Strategy update, and midwifed by firm tugs from Fermilab, CERN and Brookhaven Lab. Going by the placeholder name ELBNF (Experiment at the Long Baseline Neutrino Facility), the newborn had the impressive heft of 145 institutions from 23 countries.

The new Institutional Board (IB), convened by interim chair Sergio Bertolucci, unanimously approved a Memorandum of Collaboration that launches the election of spokespeople and a process to develop bylaws. The IB also endorsed an international governance plan for oversight of ELBNF detector projects, in concert with the construction of the LBNF facility hosted by Fermilab.

The goal of this international collaboration is crystal clear: a 40-kiloton modular liquid argon detector deep underground at the Sanford Underground Research Facility, exposed to a megawatt-class neutrino beam from Fermilab, with the first 10 kilotons in place by 2021. This goal will enable a comprehensive investigation of neutrino oscillations that can establish the presence of CP violation for leptons, unequivocally determine the neutrino mass ordering and strongly test our current neutrino paradigm. A high-resolution near detector on the Fermilab site will have its own rich physics program, and the underground far detector will open exciting windows on nucleon decay, atmospheric neutrinos, and neutrino bursts from supernova detonations.

Unlike most births, this one took place at an international meeting hosted by Fermilab; there was room for nearly all the friends and family of accelerator-based neutrino experiments. One of the critical items flagged at this meeting is to find a better name for the new collaboration. Here are a few of my unsolicited attempts:

nuLAND = neutrino Liquid ArgoN Detector

GOLDEN = Giant OsciLlation Detector Experiment for Neutrinos

Think you can do better? Go ahead. My older son, a high-priced management consultant, offered another one pro bono: NEutrino Research DetectorS.

I am too young to have been in the room when ATLAS and CMS (or for that matter CDF and D0) came into being, but last week I had the thrill of being part of something that had the solid vibe of history being made. The meeting website is here.
