SANFORD UNDERGROUND LABORATORY ATHOMESTAKE

Water level marks progress at SanfordUnderground Lab

Dewatering the former Homestake gold mineremains the top priority of the South Dakota Scienceand Technology Authority. SDSTA crews continue toimprove the dewatering system, adding a high-volume submersible pump in November andsuccessfully testing new sand-filters to remove ironfrom the water.

As of December 7, the water level was 4645, 115feet below the high-water mark, which was reachedin August.

The current "reverse cascade" pumping system usessubmersible pumps to lift water from the deep pool,below the 4550 Level, to chain of larger, 700-horsepower pumps at the 3650, 2450 and1250levels. The SDSTA plans to install a second set oflarge pumps at those levels by February 1. This willadd capacity and reduce slowdowns due to single-point failures. In addition, another high-volumesubmersible pump will be added to #6 Winze, ashaft that connects the 4550 Level to the bottom ofthe mine at 8,000 feet.

1100 Level Mine Dewatering System

Almost all of the water at Homestake comes fromsurface runoff, and most of that comes from thegiant Open Cut. Homestake Mining Co. was able tocapture a significant amount of this water at the1100 Level of the mine, preventing it from reachingdeeper levels. The SDSTA exploring options tocreate a new water-capture system at the 1100Level. Bid letting for the selected option is scheduledfor March.

The Yates Shaft re-entry

RCS Construction of Rapid City hired a number ofshaft technicians with Homestake experience to helpre-open the Yates Shaft to the 4850 Level. RCShoist operators trained in November with SDSTAoperations staff, and SDSTA staff completed hoist,cage, and skip certifications and rope cuts for all fourYates Shaft conveyances. "Cages" are mineelevator cars used for personnel and equipment."Skips" are elevator cars for rock. "Rope cuts" aremade to remove wear points on the 5,000-foot, 2-inch steel cables in the Yates and Ross shafts.Yates reentry officially began on night shift onDecember 8.

Early science support

The SDSTA is reopening Homestake to the 4850Level for experiments in advance of DUSEL. To thatend, engineering design work continued on theinfrastructure to support the LUX dark matterexperiment in the Davis Cavern at the 4850 Level.The LUX Design Team, lead by CNA ConsultingEngineers, was in Lead Dec 3-5 for a design review.

CNA also is evaluatingthe 800 Level PowderMagazine area forpossible conversion to theMajorana copper e-fo rm ing labora to ry .Geologic mapping of thespace was completed inNovember.

Information technology management

Golden West Telecommunications installed fiberoptic cabling from the floor of Kirk Canyon into theYates Administration Building for the Sanford Lab’sconnection to the ultra-high speed REED Network.Golden West is in the final stages of finalizing thefiber optic cable installation that runs from Interstate90 to the Yates Administration Building at theSanford Lab. South Dakota Bureau of InformationTechnology (BIT) staff will be on-site in January toinstall data routing equipment to complete the 10Gbps Internet2 REED connection. The connectionis capable of expansion to 50Gbps.

“Deep Science” outreach goes East RiverLeft: A poster announcingthe "Deep Science" lectureseries.

T h e S a n f o r dUnderground Laboratoryemphasized East Riveroutreach in November,with a four-day tour of the“Deep Science forEveryone” lecture series(November 17-20) .D r . Jose A lonsopresented “Neutrinos andDark Matter in the Black

Hills to audiences in Brookings, Sioux Falls, Madison

and Vermillion. Nearly 800 people attended thelectures. Dr. Alonso talked about the LUX andMajorana experiments, and he also provided anupdate on progress reopening Homestake as theSanford Underground Laboratory.

In addition, the week before Dr. Alonso’s lecturetour, Dr. Kevin Lesko flew to Sioux Falls for a longday of public outreach. Dr. Lesko was a keynotespeaker to and audience of 250 at the South DakotaTechknowlogy (sic) Summit, and he spoke toscience students at Lincoln and Washington highschools in Sioux Falls. Cheryl O’Brien arranged forDr. Lesko to meet with science teachers afterschool. These meetings will lead to follow-updiscussions about regular events with Sioux Fallshigh school students.

Extensive media coverage surrounded the "DeepScience for Everyone" lecture series. (About 2,000people have attended nine lectures since April.) Inaddition, South Dakota Public Broadcastingvideotaped Dr. Alonso’s lecture in Sioux Falls, thenproduced an hour-long DVD for use by the SanfordLab.

Dr. Alonso and Dr. Lesko also promoted the SouthDakota Department of Education’s new Davis-Bahcall Scholarships, a summer program that willallow high school seniors and college freshmen tostudy at the Sanford Lab, at Gran Sasso Laboratoryin Italy and at Princeton University.

The best kind ofoutreach

Dr. Alonso answeredquestions for at leasta half hour aftereach lecture. Hethen stayed toanswer individualquestions.

Natasha Powell, 12, also stayed late. She hadpersuaded her mother to drive her from St. Paul,Minn., to Sioux Falls for the "Deep Science" lecture.(That's a four-hour drive each way.) Natasha waitedpatiently for more than 45 minutes to askDr. Alonso if he could suggest a science fairproject. Jose told her she should choose a subjectherself -- something that really interested her. Theycontinued to talk for about 15 minutes. ThenNatasha asked, "Could I have a sample of your

yucky water?" Natasha thought it might beinteresting to test Sanford Lab’s pre-treatmentdischarge water. Look for a Sanford Lab researchproject at a science fair soon.

TRANSPARENT EARTH SYSTEM

Steve Glaser of UC Berkeley and Bill Roggenthen ofSouth Dakota School of Mines and Technologycontinue to develop the Homestake TransparentEarth Observatory. A second seismometer site wasadded on the 2000 Level in October. Power andnetwork connectivity were provided duringNovember. Both 2000 Level sites are fullyoperational. In the New Year, Roggenthen andGlaser will expand their current instrument array toinclude sites on the 800 Level, the 4100 Level andeventually the 4850 Level.

EDUCATION AND OUTREACH: BHSU hireddeputy director of education and outreach forSanford Lab, DUSEL(From Black Hills Pioneer, Wendy Pitlick)

LEAD – Education and outreach for the SanfordUnderground Lab and the DUSEL keeps growing,and on Thursday, Dr. Ben Sayler, director ofeducation and outreach activities at the labannounced that his staff is growing.

Peggy Norris, who has a PhD in chemical physicsfrom Columbia University, has been hired as thenew deputy director for education and outreach,Sayler said. In that capacity, Sayler told the boardthat Norris will work out of the Sanford UndergroundLab administrative offices and act as a liaisonbetween Black Hills State University and the lab,relating to education activities. Norris will be a BHSUemployee through the Center for the Advancementof Math and Science Education. She will work veryclosely with lab officials, Sayler said.

During the S.D. Science and Technology AuthorityJune board meeting, Sayler talked about thepossibility of hiring a deputy director for educationand outreach who will assist in coordinating earlyeducation and outreach activities, as well as assistin developing a long term education plan for federalconsideration which will be included in the DUSELproposal to the NSF.

The original job posting states, “CAMSE (Center forthe Advancement of Math and Science Education)seeks a visionary leader in science education to helpdirect this work and maximize learning opportunities

for K-12 students and teachers, university studentsand faculty, and the general public.”

Sanford University Underground Laboratory DirectorDr. Jose Alonso said he has worked with Norris on anumber of past projects, and through the years thetwo have become good friends.

“I am delighted that the selection process came outthis way because she will be a wonderful person forthis job,” Alonso said.

Norris is currently the chairman of the LawrenceBerkeley National Lab Diversity Council, and Alonsoreported that she is very prominent nationally inphysics education.

Although her official start-date is not until January 5,Sayler said Norris is already helping with educationand outreach efforts. From her current station atLawrence Berkeley National Lab she has beenhelping members of the Homestake Collaborationprepare for their annual review with the NationalScience Foundation, and she is preparing for anational conference about creating science andtechnology outreach efforts.

“We’re gaining momentum, it feels like, by the day,”Sayler said. “Strengthening the tie betweeneducation and outreach and the Sanford Lab to helpimprove communication is going to be reallyvaluable.”

Upon completing her work in Berkeley, Sayler saidNorris plans to move to Lead.

UPDATE FROM THE DUSEL EXPERIMENTDEVELOPMENT COMMITTEE (DEDC)

As the S4 proposal submission deadline of January9, 2009 rapidly approaches, the DEDC are focusingtheir efforts to help the various collaborations andproponent groups from across the spectrum ofactivities which will comprise the DUSEL laboratory.

A common suite of resources is posted now at:http://www.ems.psu.edu/~elsworth/projects/dusel/s4/resources.htm

These resources are common to all proponentgroups. As an aid to proponents, the packageincludes (1) a description of the evolving HomestakeFacility and what it will ultimately offer; (2) a listing ofall known physics and non-physics collaborations;(3) a NSF proposal checklist; (4) examples of prior

MREFC proposals as a target; (5) E&O resources;(6) a sample WBS; and (7) a mechanism to checkthat facility resources and experiment needs arecompatible. In addition, perhaps most importantly, amechanism to codify this compatibility betweenexperiment and facility with a consultation letter thatmay be an important part of a proposal.Although these resources are common to alldisciplines, the physics and biology-geoscience-engineering groups have taken different approachesin aiding the component collaborations to readiness.

The physics community has relied on close personalcontact with collaboration groups, the supply of theresources noted above, collaboration workshops atprofessional meetings and contact throughconference calls.

The biology-geoscience-engineering community hasorganized a network of science and responsivenessreviews for draft submissions completed byDecember 1. These activities will feed into aninformational and review-feedback meeting planned9-5 pm for the Hotel Nikko during the AmericanGeophysical Union meeting in San Francisco onDecember 18th.

A series of conference calls have refined the form ofindividual experiments which will be submitted forthe initial suite of experiments for S4. Since nospecific resources in the S4 opportunity have beenallocated for Biology, Geosciences, Engineering andother cross-cutting areas, the proposals will have tocompete within the existing grant submissionstructure of NSF. Consequently, working groupshave been busy determining the most appropriateprograms within NSF as receptors for theirproposals. The coordination activities will culminatewith sessions on Geoneutrinos and UndergroundScience at the Fall meeting of the AmericanGeophysical Union (San Francisco, December2008).

Hopefully, these two different approaches incoordinating and in aiding the activities of thecommunity will contribute positively to the maturingscience plan for DUSEL-Homestake.
