Our samples were pretty diluted

1 Minute Count at 925 volts 2cm ~17k 1 minute count at 925 volts 1cm 28740 counts

Right half only 1 minute count at 925 volts 1cm R1 15460 counts

Both halves 1 minute count at 925 volts 1cm R12 28966 counts

Left half only 1 minute count at 925 voltes 1cm R2 15257 counts Question 3.1 we may not really have to do Exercise 3.4 238.9 microseconds between pulses observed calculated was 236.2

Now with the blank disk measurements in script

removing both halves background count is 32
