Nuclear Physics

What's new:
The items in belwo are taken directly from Kathy and Wendy's document, so they are voiced as thngs that need to be done. They have all been addressed.

General

• Should start up on first tab
• Pause and Play settings stay where they are placed when you switch panes.
• Remove help buttons since there is no help.
• Have the legend on each panel only display the applicable items to each tab.
• Button labels are illegible in Java 1.5
• You can’t see what the buttons (Reset, Help, Pause) say.
• Change tabs so that they look like our new Tabs. Not very do-able. I made them bigger, though, and more prominent

Alpha Radiation

• The atoms bounce around to fast. There speed needs cut down to 25% of it’s current speed and then we’ll look again
• Change the label “Running time to decay (msec)” to “Time to decay” and can the units be placed with the number?
• After the decay the alpha particle is moving around in the background instead of in the foreground.
• The lower section should look like a graph sitting in the play area rather than more play area. During interviews all the students thought it was a physical representation and could not make sense out of it. If it looks like a graph, it may go over better. Try making the axis lines more prominent also.
• gridlines overlay the profile, and there's a label to further suggest it is a graph
• In lieu of a rewind button I added a control that will pause the simulation at the start of alpha decay. The user can then step through the decay.

Fission:

• Speed reduced to half.
• Graph in lower portion as in Alpha Radiation panel
• nucleus on graph pane of single nucleus fission module flashes oddly sometimes

Chain Reaction panel

• Remove “Number of” and just have the label 235U nuclei (with spelling correction) as the label for each spinner.
• Remove “Percent” put a % sign to the right of the box or better yet, in the box with the number so that it’s formatted the same as the number.
• I would suggest a vessel that’s half as thick.
• There’s a wired little box that shows up around Enable Containment Vessel when you choose the check box but once you do something else in the control panel it disappears.
• "Enable Containment Vessel" color isn't the same as the other labels in the panel

Controlled Reaction

• The neutrons in this panel have tails and look like photons. They should just be round balls.

To Do

• The rest of th item in Kathy and Wendy's list
