Particularly unique is the discussion on Polya distributions and the width of the pulse spectrum on pp. 124-126 (pp. 10-12 as scanned).

as a white diffuse reflector.
- 1992 article about contaminants in
Halon and how to keep Halon clean.
- 1997 article about a replacement for
Halon.

of integrating spheres.

Jim Napolitano of the Daya Bay
Group's memo on water purification.

- Compton Scattering - main point is
that the minimum energy needed for a gamma to make a Compton scattered
electron above Cherenkov threshold in water is near to 0.4 MeV, not
1.0 MeV, as previously reported.

- DUSEL Lead Meeting
- Another Talk
04/24/2008 - Wavelength Shifter in Water Cherenkov Detectors - Harry was launched in this direction by Hank Sobel
during a meeting at the Homestake meeting. We may be able to get
a factor of 4 in pulseheight by adding a modest additive to our
water!
04/18/2008 - Short memo on the
Californium source -- we have a stronger source than expected!
We ended up with the `long source,' not the `short source', which
explains the rate discrepancy.

- Joel's key plots for APS meeting
- Multiplicity Plot - With Cf-252, With Gd
- Multiplicity Plot - With Cf-252, No Gd
- micro-K Time Between Events
- Overall Rate Discrepency - 20/second expected 252-Cf... 1000/second
observed for neutron capture. Perhaps 250-Cf!

- A Water Cherenkov Counter.... this
article describes a detector much like our prototype built in the
1980's.
- PBAR: A Superconducting Magnet.... this
article describes the PBAR detector, that incorporated a water Cherenkov detector
based on that described above.
- Technique for Painting.... this
article describes high reflectivity white paint.
Another article about very white paint, and an article about white reflective standards. These paints/materials are not compatible with water.
- Sintered Halon as a diffuse.... This
article describes how to make a sintered compound that has great white
reflectivity and is compatible with water.
