Balloon Design

8 Ft Diameter Balloon

To carry 7.4 Kg

Take Counts at 1000 feet

Safely recover without any problems

Website Status

Created directory structure mirroring last year's example

2006InternsAssets – Any images for use on websitePictures – Raw folders from cameraResource – Any documents for use on website

Directories can be made as subdirectories in futureAssets -> 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

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

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 feet115 cubic feet = 3.25643736 cubic meters3.25 cubic meters x 1000 g/cubic meter = 3256.43736 g3.25643736 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

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
