Rate Estimates
Previous experiment at the IAC
Condition | Grade Calculation |
If all Homework is complete and Simulation project is turned in on time | (50%) Homework + (50%)(Simulation Project) |
If 1 homework set is incomplete or more than 48 hours late | (60%)Homework + (40%)(Simulation Project) |
Otherwise | (70%)Homework + (30%)(Simulation Project) |
NaI rate Ratio of positron to electron beam
Assumed Geometry
Assume a 2 mm thick Tungsten target that is 1" square
The target is located at -80 < Z < -80.2 The NaI crystal is 2.32" or 56.49 mm in diameter The NaI crystal is 8" from the target then the opening angle is atan(2.32/8/2) = 8.25 degrees
