Physics 104 Lab - Setup Instructions: Diffraction and Interference

Physics 152 Set Up Instructions:
Measuring the Radioactivity of a Smoke Detector
with Vernier Radiation Monitors

Return to Main setup instructions

The setup; Vernier Radiation Monitor, LabPro interface,
USB & power cable, smoke detector, rods & clamps
The radiation monitor is held by a test tube clamp,
attached to long rod

The is connected to the Dig/Sonic1 port of the LabPro Interface.
Note small squares of paper left for students
Sort metal pieces into piles, place on
front bench (Phys 152) or side bench (Phys 104)

The Chart of the Nuclides are stored in this cardboard tube

There are several versions of the charts in the tube.
Use the newest ones (Seventeenth Edition - Revised to 2009)
The charts are huge and nearly cover the entire bench

The following demo is no longer used (old Geiger counters are too finicky);
photos are left here for completeness:

The demo setup
The scope trace

The Geiger counter in action
Connections on back of counter:
Middle wire to Geiger Tube
Bottom wire to Oscilloscope
Gray wire to Timer
Brown wire to 120V AC

See-thru oscilloscope
Connection from counter

Geiger tube with Radium source
(in small oval containers: Watson has them!)
Geiger tube in stand over source

High voltage gets set to 1000 volts
Turn timer on, or counter won't work!
