Mu2e, or the Muon-to-Electron Conversion Experiment, is a particle physics experiment at Fermilab in the US. The goal of the experiment is to identify physics beyond the Standard Model, the conversion of muons to electrons without the emission of neutrinos, which occurs in a number of theoretical models. Project co-spokesperson Jim Miller likens this process to neutrino oscillation, but for charged leptons. Observing this process will help to narrow the range of plausible theories; the experiment will be 10,000 times more sensitive than previous muon to electron conversion experiments, probe energy scales up to 10,000 TeV. Physicists have been searching for flavor violation since the 1940s. Flavor violation among neutrinos was proven in 1998 at the Super-Kamiokande experiment in Japan. In 1989, Russian physicists Vladimir Lobashev and Rashid Djilkibaev proposed an experiment to search for lepton flavor violation; the experiment, called MELC, operated from 1992 to 1995 at the Moscow Meson Factory at the Institute for Nuclear Research in Russia, before being shut down due to the political and economic crises of the time.

In 1997, American physicist William Molzon proposed a similar experiment at Brookhaven National Laboratory. Research and development on the MECO experiment began in 2001, but funding was pulled in 2005. Mu2e is based on the MECO experiment proposed at Brookhaven, the earlier MELC experiment at Russia's Institute for Nuclear Research. Research and development for the Mu2e experiment began in 2009, with the conceptual design complete in mid-2011. In July 2012, Mu2e received Critical Decision 1 approval from the Department of Energy, about one month after initial review. Project Manager Ron Ray asserted, "I know of no other project that has received sign-off that after review." Funding of the Mu2e experiment was recommended by the Department of Energy's Particle Physics Project Prioritization Panel, in its 2014 report. Groundbreaking on the detector hall took place on April 18, 2015, with the hall expected to be complete in late 2016. Commissioning of the experiment is anticipated in 2019, preliminary results are possible by around 2020.

The experiment is anticipated to run for three years. Improvements to the detector may increase the sensitivity of the experiment by one to two orders of magnitude, allowing a more in-depth study of any charged lepton conversion that may be discovered in the initial run; the Mu2e apparatus will be 92 feet in length, will consist of three sections. The total cost of the experiment is $271 million. Repurposed elements from the Tevatron collider will be used to generate and deliver an 8 GeV proton beam; the protons would be extracted from Fermilab's Delivery Ring through a non-linear third-integer resonance extraction process and sent in pulses to the tungsten target. These protons will collide with the tungsten production target in the production solenoid, producing a cascade of particles including pions, which decay into muons. Mu2e will produce between 500 quadrillion muons per year. For every 300 protons hitting the production target, about one muon will enter the transport solenoid; the 4.5-Tesla magnetic field of a production solenoid will direct some of the particles produced into an S-shaped 2-Tesla evacuated transport solenoid, consisting of 50 separate superconducting electromagnets, which will select muons by charge and momentum, carry the desired slow muons to the detector after some time delay.

On entering the detector solenoid, the muons will stop in an aluminum target as thick as ten layers of aluminum foil, entering orbitals around nuclei within the target. Any muons which convert into electrons without emitting neutrinos will escape these orbitals and enter the detector with a characteristic energy of around 105 MeV; the detector itself consists of two components: a straw tracker to measure the momentum of outgoing particles. An electron with energy of around 105 MeV will indicate that the electron originated in a neutrinoless muon conversion. In order to disturb the path of the electrons as little as possible, the tracker uses as little material as possible; the wire chamber tracker consists of panels of 15-micron-thick straws of metalized mylar filled with argon and carbon dioxide, the thinnest such straws used in a particle physics experiment. Electronics at each end of the straws will record the signal produced when electrons interact with the gas in the straw, allowing the trajectory of the electrons to be reconstructed.

The rate of neutrinoless conversion of muons to electrons was constrained by the MEG experiment to less than 2.4×10−12, further constrained to 7×10−13 by the SINDRUM II experiment at the Paul Scherrer Institute in Switzerland. Mu2e has an expected sensitivity of 5×10−17, four orders of magnitude beyond SINDRUM II, meaning that it will see a signal if as few as one in 100 quadrillion muons transforms into an electron; as of October 2018, the Mu2e collaboration included 240 people from 40 institutions in six countries. The collaboration is led by co-spokespersons Douglas Jim Miller; the project manager for Mu2e is Ron Ray. Comet Experiment Erlich, Ralf. "The Mu2e Experiment". Max-Planck-Institut für Kernphysik

Old Athens, Alabama Main Post Office

The Old Main Post Office in Athens, Alabama known as Washington Street Courthouse Annex, was built in 1933. Located one block from the Courthouse Square, the Neoclassical building was constructed by the Works Progress Administration; the front is divided by 8 Doric columns. Granite stairs flanked by original cast iron lamps lead to 3 sets of doors in the center bays; the lobby features marble floors, wainscoting and door trim. The post office was converted to a courthouse annex in 1979, it was listed on the National Register of Historic Places in 1982. List of United States Post Offices


Pittiplatsch known as Pitti for short, is a German fictional kobold character, famous in East Germany as a puppet character on children's television. He first appeared in 1962 in the television series Meister Nadelöhr erzählt renamed Zu Besuch im Märchenland; the character was co-created by the writers Ingeborg Feustel and Günther Feustel, the sculptor Emma-Maria Lange, the puppeteer Heinz Schröder. The Pittiplatsch hand puppet was puppeteered and voiced by Heinz Schröder until his unexpected death in April 2009. Norbert Schwarz succeed Schröder as Pittiplatsch's puppeteer in 2009. In May 2010, it was reported. Today, the short puppet colour films created for East German television are still broadcast on the Sandmännchen children's TV program, but there are no new productions for TV. However, new merchandise is still produced. Since 1993, the puppeteer ensemble has been performing live; the death of Pittiplatsch's puppeteer Heinz Schröder in April 2009 put the show on hold until August. On November 26 2019, new episodes started airing on KiKA & rbb.

The English Version Release on The shorts were shown in the United States as part of the Nickelodeon series Eureeka's Castle On November 23, 1955, the first episode of the long-running television series Meister Nadelöhr erzählt was broadcast, starring Eckart Friedrichson as the master tailor Meister Nadelöhr, who lived in his tailor parlour in fairyland and told stories to the viewers. In the beginning, he was accompanied by two live-action canaries Zwirnchen and Röllchen, who were replaced with puppet characters. In February 1958, the eponymous bear mascot of the children's magazine Bummi was added to the series. Another puppet joined in 1958. Both characters were portrayed as dutiful and honest. However, the makers felt; the puppeteer Heinz Schröder had the idea of a character based on the kobold, a sprite of German folklore, to serve as comic relief. Schröder imagined a naughty little boy who didn't age, had magic abilities and didn't need to be parented. In cooperation with the writers Ingeborg and Günther Feustel, the designer and sculptor Emma-Maria Lange created a first model.

The work resulted in a black-skinned boy with full hair and long legs wearing patent leather shoes. This design was rejected by Schröder; as a result, most of the hair was removed, the legs were crooked and the leather shoes were replaced with felt ones. Pittiplatsch, as the kobold was named needed an appropriate voice. Schröder and the other puppeteers spent one whole night trying all possible pitches of voice they could think of without success. At the last minute, Schröder gave up and shouted "I can no longer" with a squeaky voice, his colleagues and the director Erich Hammer agreed that this squeaky voice was just right for Pittiplatsch. In 1962, Pittiplatsch debuted on television as a new companion of Meister Nadelöhr, puppeteered and voiced by Schröder. Unlike Bummi and Schnatterinchen, he was introduced as a more cheeky character. In his first appearance, Pittiplatsch stole some pudding; some parents and teachers were concerned that children would only learn bad behaviour from Pittiplatsch.

This caused Pitti to be removed from the show after a few broadcasts. However, thanks to a lot of support from children who protested against this decision by mailing to the East German television, Pitti was brought back. Since he became a recurring character on the show Meister Nadelöhr erzählt, renamed Zu Besuch im Märchenland, appeared in other East German shows and media. A lot of the Pittiplatsch-related stories in numerous media were written by Ingeborg and Günther Feustel, who created many other works for the country's children's media as well. Pittiplatsch was a recurring character on the show Zu Besuch im Märchenland Meister Nadelöhr erzählt. Following the retirement of Eckart Friedrichson, who died in 1976, Meister Nadelöhr was replaced by the character of Fabian in September 1978, played by Klaus-Peter Pleßow; the kobold was present one thousand times in the Abendgruß of the daily children's show Sandmännchen, the first time on June 17, 1962. These stories were only a few minutes long.

In the early 1970s, Pittiplatsch and the duck Schnatterinchen started to appear in the short stories. The makers searched for a third character. At first, they reused the puppet Struppi known from the older defunct show Flax und Krümel, he was replaced by the newly created dog character Moppi, who debuted on April 3, 1976 and starred alongside Pitti and Schnatterinchen in more than 400 Abendgruß episodes. As with Meister Nadelöhr, Pittiplatsch and his friends still starred alongside their human companion Fabian in some Abendgruß episodes. Many of the short colour films are still shown on TV, but not the white films. There were longer Pittiplatsch films produced, one of, Pittiplatsch reist ins Koboldland, where Pitti experienced adventures with his siblings in Koboldland. Several books and audiobooks starring Pittiplatsch were released in East Germany being written by Ingeborg Feustel. Many of them have been re-released in reunited Germany, new Pittiplatsch-related works have been published as well.
