  1. General Project SCIPP Internship Santa Cruz Institute Particle Physics 7/6/06 Ryan, Alex, Michael, Thomas, Julie Anne, Megan SCIPP Intern Summer 2006

  2. Balloon Design • 8 Ft Diameter Balloon • To carry 7.4 Kg • Take Counts at 1000 feet • Safely recover without any problems

  3. Design of Box • Basic box filled with foam. • Tethered probably with one line.

  4. Briefing Outline • Website Status • Website To-Do • Fitting Under Federal Regulations • Bad “C” Scintillator Panel • Our Findings About the Panel

  5. Website Status • Created directory structure mirroring last year's example • 2006Interns • Assets – Any images for use on website • Pictures – Raw folders from camera • Resource – Any documents for use on website • Directories can be made as subdirectories in future • Assets -> Fireworks images – So that buttons...etc. can be edited in the future • Pictures -> 06-07-23 – Raw folders from camera • Resource -> Muon Lifetime – All documents are stored in one location

  6. Website Status Cont. • All references to 2005 have been removed in new index template • New buttons have been made to reflect 2006 • Pictures have been uploaded to the index template for temporary use • Link made on outreach page on SCIPP to point to new 2006 site

  7. Website To-Do • Fix broken links from the move to new folder • Add intern bios, photos, student papers, resources, acknowledgments • Update Interns 06 banner to distinguish it from last year's banner

  8. Fitting Under Federal Regulations • Federal regulations state that you do not need a waiver if the balloon is under 6ft in diameter • Or if the balloon is less than 115 cubic feet • 115 cubic feet = 3.25643736 cubic meters • 3.25 cubic meters x 1000 g/cubic meter = 3256.43736 g • 3.25643736 kg lift = 7.17921547 lbs lift • This is much less than the necessary 7.4kgs lift needed at the moment • Possibly can eliminate weight by using one scintillator with two PMTs • This would eliminate an entire scintillator massing 0.89kgs

  9. Bad “C” Scintillator Panel • Determined that the “C” scintillator panel was receiving much more static than other panels • Swapped bases – not the problem • All other panels still worked fine • Put all PM tubes on the oscilloscope under a coat • “A” and “B” worked as expected • “C” looked like garbage • Decided to open the panel to determine what was wrong with the PMT

  10. Our Findings With the PMT
