SA in charge against Sri Lanka

first_imgThe day started well enough for the tourists as they took South Africa’s remaining four first-innings wickets for just 19 runs to dismiss the hosts for 286; Suranga Lakmal (5-63) claiming a first Test five-for.But the tourists’ top-order flopped, with three further wickets falling before lunch to make it seven for the session, in stark contrast to the six in total on day one.Vernon Philander was the pick of the Proteas bowlers, taking 3-35, though greater application was shown by the Sri Lankan middle and lower order; Dhananjaya de Silva doggedly fighting through to 43 not out when play was ended 22 overs early due to bad light.In the morning session, South Africa’s final four wickets lasted all of 8.5 overs as they were bowled out for their lowest first innings Test total at St George’s Park in nine years.Philander (13) was the first to fall, caught at deep square-leg when top-edging a pull off Nuwan Pradeep (2-66).Lakmal then claimed his five-for, in his 32nd Test, Keshav Maharaj edging behind for a duck, before Kyle Abbott was run out without scoring and Quinton de Kock (37) was bowled by a Pradeep yorker to end the innings.However, Sri Lanka’s reply got off to a terrible start as Dimuth Karunaratne (5), Kusal Perera (7) and Kusal Mendis (0) were dismissed inside the opening eight overs of their innings.Karunaratne first inside-edged a Kyle Abbott (2-49) delivery onto his stumps, before Perera and Mendis both edged loose drives behind off Philander and Abbott, respectively.Skipper Angelo Mathews (39) led the way after lunch, while Kaushal Silva (16) and Dinesh Chandimal (28) too tried to occupy time at the crease, though runs proved to be a struggle.Philander ultimately accounted for both Silva and Chandimal lbw either side of tea, while Kagiso Rabada (1-63) had Mathews out, caught at third slip, sandwiched between those strikes.But just as it looked like Sri Lanka might collapse to the close, De Silva battled on bravely, although he should have been caught by left-arm spinner Keshav Maharaj off his own bowling when on 27.Maharaj (1-30) did at least pick up the scalp of Rangana Herath (24) lbw, after he missed an attempted reverse sweep.last_img read more

Slideshow: Muon g–2 ring takes final steps to new home

first_imgOver the next 6 months, physicists will cool the ring to superconducting temperatures and test its magnetic field. Until then, they can’t be sure if the delicate ring survived the journey intact. The team hopes to begin taking data in March 2017. Fermilab Fermilab After waiting out a storm near Norfolk, Virginia, the ring made it safely to the Tennessee-Tombigbee Waterway north of Mobile, Alabama. The team decided to move Muon g–2 to Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois. But they knew they couldn’t do without the experiment’s delicate storage ring, which was capable of producing an exceptionally uniform magnetic fie Fermilab Brookhaven National Laboratory Once it reached Lemont, Illinois, the ring was loaded back onto a truck for a 3-night journey across shuttered roadways to Fermilab. Brookhaven National Laboratory The Muon g–2 ring began its life at Brookhaven National Lab in Upton, New York, where it was part of an experiment that ran from 1999 to 2001. The project produced tantalizing hints of new physics, but to be sure, scientists needed to repeat the experimen Brookhaven National Laboratory The ring left Brookhaven in the wee hours of 24 June 2013, traveling by truck down Long Island’s William Floyd Parkway to the Smith Point Marina. The ring passed the St. Louis arch as it traveled through Missouri. Three thousand people turned up to see the ring arrive at Fermilab on 26 July 2013. It had traveled 5000 kilometers by land, sea, and river.

Brookhaven National Laboratory Darin Clifton/Ceres Barge Fermilab A little more than 1 year ago, the Muon g–2 (pronounced “g minus two”) storage ring set out on an epic journey. Beginning at Brookhaven National Laboratory in Upton, New York, it traveled 5000 kilometers down the Atlantic coast, up three rivers, and across several highways to reach its new home at Fermi National Accelerator Laboratory (Fermilab) in Batavia, Illinois. The ring is a key part of an experiment to measure a property called magnetic moment in muons, much heavier subatomic-particle relatives of electrons. Scientists saw tantalizing hints of new physics during Muon g–2’s first run at Brookhaven from 1999 to 2001. But to be sure, they need to run the experiment again with Fermilab’s more powerful muon beam—which is why they moved the 15-meter-wide ring halfway across the country by truck and barge. Science talks to Chris Polly, Muon g–2’s project manager, about some highlights of the trip and what’s in store for the ring at its new home. For more about Muon g–2’s journey, check out the slideshow above.Q: What’s happened at Fermilab since the ring arrived last year?A: Since the ring got here, we’ve been constructing the new home for the magnet. It needs a building with very special temperature and floor stability requirements, and there wasn’t any place here that would accommodate it. After the ring was successfully transported, the work to construct the experimental hall got going at 100%.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Just last week, we rolled the magnet out once again. We had [hauling company] Emmert International come out and help us with the final leg of the journey. They brought it out on Saturday morning around 8 o’clock and towed the ring about a mile to the new building.Then, of course, they needed to get it into the building. We were clever enough to remember to design a hole big enough for it to fit through. There’s no door that you could possibly make that would accommodate it, since it’s 50 feet [15 meters] wide. It kind of looked like a giant CD player, when the whole ring just went sliding into the side of the building on a rail system. Inside, it still looks like the ring is levitating, because it’s on some scaffolding as they slowly lower it down to the experimental floor, which is about 16 feet [5 meters] below ground level.Q: What was the hardest part of the moving process?A: From my perspective, one of the hard parts was finding the right vendor for the job: a transportation company that could safely move this magnet and would have the political skills necessary for all the hurdles when it comes to trying to move a 50-foot-wide thing through areas where nothing that wide has ever been transported before. That was quite a task, but Emmert International was fantastic to work with. In fact, we’re going to meet their crew at the bar in about 2 hours for a beer.Q: What was the scariest moment?A: When the barge was coming up Cape Hatteras, there was a storm blowing up and the wave data started getting bigger, and bigger, and bigger. And we’re like, “Oh, man.” Cape Hatteras is well known as a shipping graveyard. So we made the decision to pull up into Norfolk and wait out the storm before we continued.Q: The most exciting?A: Truly the most exciting moment by far was the reception the ring received when it arrived at Fermilab. We invited the public to come out and see it when it arrived. Three thousand people showed up. The lab eventually had to close the gates because there wasn’t any more room. To have the ring roll down by Fermilab’s reflecting ponds, and a crowd of 3000 people cheering—I don’t know how we’ll ever rival that moment in a science experiment, it was just amazing.Q: The ring is so delicate. Do you know yet if all its systems survived the journey?A: We’ve done all the tests we can on the ring while it’s warm and not hooked up to a cryogenic plant. You can measure the electrical resistances, put a voltage on it, make sure it’s not leaking current, check the piping systems that will hold liquid helium to make sure they’re intact. We’ve done all those basic tests and everything looks good so far.But this is a superconducting magnet, and for it to operate, it has to be cooled down to liquid helium temperatures. That’s the name of the game for the next 6 months. We will be rapidly trying to build the superconducting systems and connect the cryogenic wires and get the power supply operational so we can do the ultimate test, which is to cool and power the magnet.Q: When will the experiment start running?A: You can get it cold in about 6 or 7 months. But it’s not just good enough to have a strong enough magnetic field. It also has to be an extremely uniform magnetic field. So after the magnet is powered, that immediately begins a phase where we spend 9 months to a year iteratively changing little pieces of steel, adding little pieces of wire with currents flowing through them, where we effectively try to “shim” the magnetic field—applying corrections to make it very, very uniform.And then you still have to be able to see the muons somehow. They’re not visible to the naked eye or anything—it takes a very sophisticated set of detectors and electronics and a data acquisition system. There’s a lot to the experiment beyond just the magnet. So all those systems are being prepared.By the time that’s all done, that’s still about 2, 2-and-a-half years from where we are today. The current start date is March 2017, but we’re hoping there are a few tricks we can play along the way that might make it go a little faster. Of course, you never know—it’s science. At the marina, it was lowered by crane onto a waiting barge. It would be carried by boat down the Atlantic coast, around Florida, and up three rivers to Illinois. Fermilab Fermilab Building a new ring at Fermilab would have cost $25 million, whereas moving the existing one from Brookhaven cost $3 million. Heavy-haul transport company Emmert International designed a 40-ton transport fixture to hold the ring steady during its journey. Fermilab spent the next year building a new home for the ring. It finally moved in on Wednesday, 30 July 2014. Spectators came out to see the ring at several points during its 1-month journey. Many compared the sight to a UFO.
