  1. UNO R&D and mUNO Possible early use of Henderson Upper Campus • UNO collaboration has submitted an R&D proposal covering • Excavation R&D of large caverns • Cavity Liner R&D, develop water containing liners • PMT R&D, design and prototype PMT mounting supports • mUNO; small scale test water Cherenkov detector, outreach • Photosensor Development • Software monte carlo studies These items require tests in a mining environment. Possible upper campus user

  2. Cavity Liner R&D Purpose; develop water containing liners to seal the walls and floor to contain the water volume in a large water Cherenkov detector; 60m Cross section of UNO detector with a shotcrete liner contain- ing the water volume and PMT’s and supports again the wall 60m

  4. Cavity Liner Tests & mUNO The cavity liner tests require a liner to be installed in a cavern or “cistern” of very rough dimensions, 3x3x3m deep, and to be filled with water to check the containment. This has been proposed for the Henderson Mine. preliminary estimates of excavation, ~$45K. This allows the opportunity to set up a small PMT array to be readout. This forms a “mUNO” detector.

  5. Cavity Liner Tests & mUNO • The purpose of this test includes • tests of the cavity liner and may include PMT mounting schemes • Experience in building & operating an “UNO” like detector at • Henderson. • Includes end to end shakedown of a real detector at Henderson • with a DAQ system that is remotely readout and controlled. • Enables Physicists to learn to work in Henderson mining environment • Enables Miners to experience Physicists in a mining environment

  6. mUNO Outreach • mUNO provides an opportunity for hands experience for HS students • to participate in a complete mini-experiment. • In 2001 HS students in the region have participated in Snowmass Area • Large Time-coincidence Array (SALTA) and have experience with PMT • detectors readout at their schools using QUARKNET cards. In 2004, • SALTA schools participated in measuring cosmic ray rates in Henderson. • (see Dan Claes presentation) • mUNO participation forms excellent next step progression of outreach. • Training workshops would be set up at Henderson and select students • could participate in some testing, setup and routine operation. The • readout could be web based providing events displays of cosmic rays • in real time that are accessed by many schools around the state.

  7. Upper Campus Ideas • UNO R&D proposal is a two year plan, with the 1st year test cistern • construction at the Colorado School of Mines and in the 2nd year • construction of two test cisterns at Henderson including building the mUNO. • Current plans are to use existing cavern space provided by Henderson. • UNO R&D project could provide an excellent first use of the • DUSEL/Henderson upper campus section if available.
