UNO R

UNO RD and mUNO Possible early use of Henderson
Upper Campus

• UNO collaboration has submitted an RD proposal
  covering
• Excavation RD of large caverns
• Cavity Liner RD, develop water containing
  liners
• PMT RD, 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.

Cavity Liner RD
Purpose develop water containing liners to seal
the walls and floor to contain the water volume
in a large water Cherenkov detector
60m

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.

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

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.

Upper Campus Ideas

• UNO RD 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 RD project could provide an excellent first
  use of the
• DUSEL/Henderson upper campus section if
  available.
