TRANSPARENCY ARCHIVE

We have some posters that have been used for various committee meetings and site visits at IUCF:

• Chris Allgower's poster on the Pb-glass and electronics setup from the December, 2000, meeting of the IUCF Visiting Committee.
• Ed Stephenson's poster on the polarized deuteron test as presented at the Polarized Source and Target workshop held in Brown County, September, 2001.

The transparencies available here are in Microsoft PowerPoint.

Transparencies made fresh from Ed's seminar on April 12, 2002:

• Current participants list.
• General Summary outlining the concept of the CSB experiment.
• Diagram and spectra from the small angle - silicon detector luminosity system.
• Spectra from the 44-44 degree scintillator lunimosity system.
• Spectra from the 25-44 degree scintillator luminosity calibration system.
• Summary of calibration and luminosity issues after the first deuteron run.
• "Turning the Corner", which summarizes the issues in going from proton commissioning to deuteron production.
• Channel scintillator spectra showing full delta-E(2) by delta-E(1) and a gated version emphasizing the alpha window.
• Channel scintillator spectra showing E by delta-E(2) with and without alpha gates.
• Missing mass gated on alphas (~7000 events).
• Pb-glass pulse height summed over nearest neighbors and with initial cuts on gammas.
• MWPC and time spectra for events showing at least one good gamma in the Pb-glass array.
• Channel scintillator spectra gated to emphasize events with one good gamma in the Pb-glass.
• Target traceback for 3-He, and alphas selected to go with one good gamma.
• Missing mass gated on one good gamma and other cuts.
• Conclusion slide with plans for the near term future.

Transparencies from Chris Allgower's colloquium talk at the University of Kansas, April 3, 2002:
(Note: Some pages have figures that may look odd on-screen, but they print okay - CA.)
(29 pages, total size = 1.44 Mb)

From the Program Advisory Committee meeting of December 17, 2001:

• Cover with the "logo" and Web site address.
• Scientific motivation review.
• Summary of the INT Workshop in August.
• The Management Plan and how we have met the objectives.
• Sensitivity Limits, a new version.
• Beam time request.
• Personnel planning.

From the National Science Foundation site visit talk of December 13, 2000:

• Title lists the collaboration with some names highlighted
• Theory reviews the connections to quark mass differences and other CSB experiments
• Channel shows the latest magnetic channel drawing with parts labelled
• Two gamma introduces the background from double radiative capture
• Separation shows how to use missing mass to separate radiative capture from the alpha-pi0 channel
• Gamma geometry indicates that using the position of the gammas in the Pb-glass is of no additional help
• Limits shows the Monte Carlo simulation for 2 months of running with a total alpha+pi0 cross section of 2 pb, and explains how the cross section and count rate were determined
• Objectives gives a time line for the experiment with explanation of important milestones

Transparencies made available to Roy Holt for his presentation on few body physics at the Jefferson Lab Town Meeting December 1:

• Summary describes the experiment and puts it into context
• Additional shows the 2 months/2 pb Monte Carlo along with some general explanation

These are most of the transparencies used by Ed Stephenson for his part of the presentation of the CSB experiment to the Program Advisory Committee in June, 2000:

• Overview shows a sketch of the channel and mentioned various experimental highlights
• Channel is another view of the channel marking detectors and other features
• Target shows the reconstruction of the target spot using wire chamber information
• Scintillator shows a simulation of the particle identification for 4He
• Trigger has scintillator spectra from the test run with thresholds marked for the 4He trigger
• Pb glass shows the Pb-glass in an early arrangement and mentions features
• Pb glass spectra shows cosmic ray spectra for IUCF and ANL modules along with simulations of the gamma ray location and opening angle
• Missing mass shows the features used to discriminate between alpha+pi0 events and double radiative capture background
• Final polarization shows the Monte Carlo simulation of missing mass for 2 months of running with a 20 pb total cross section, along with some comments
• Review lists the points made by the technical review committee in February and what has been done to address each point

Ed also gave a talk at the University of Idaho on CSB in August, 2001. For that, he prepared some introductory transparencies:

• Introduction 1 discusses isospin, charge independence, and charge symmetry.
• Introduction 2 connects charge symmetry with isospin conservation and introduces quark and electromagnetic terms.
• Introduction 3 shows two secondary CSB effects that appear in OBE models.
• Introduction 4 reviews the experimental situation. The theory workshop is mentioned.
