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

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

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

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

5. 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. 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. 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. 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. 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
