Run the Exercise
To run this exercise click here: []. Before you can run the exercise you need to have booked a time slot (see below) and have installed the appropriate LabView plug-in (as explained on the main RoboLab page).

Booking
To book a time slot for using this remote controlled laboratory you must contact Jon Petter Omtvedt (UiO). Please provide full name, affiliation and when you would like to run the exercise. You will not be able to use the system before you have received a username and password.

Student Guides

 * Neutron activation of Ag with a Pu/Be source
 * How to calculate end-of-irradiation yields
 * General theory on n-activation analysis (from NucWik NRC textbook)
 * General theory on desintegration (from NucWik NRC textbook)

Suggested Preparation before RoboLab Exercise

 * Preparations before you perform the RoboLab exercise. Find relevant data and information.
 * Simulation of Two-component Decay. Simulate the count rate resulting from desintegration of two nuclei with different half-lives and a constant background.

Pictures and Videos
Pictures and videos from the physical laboratory (click on the picture/video for full-size image): Overview picture: The 2 m long transport rail exits the hole in the 1m thick concrete wall where the Pu/Be source is located and enters the detector tower. To the right is the rack with counting electronics and pneumatic control electronics. || Picture of the counting tower also showing position of the webcam. || View inside lead tower, the silver disk is placed inside the red holder. The detector (2" NaI) can be seen under the red holder. || The counting electronics (left and middle) and the pneumatic control (right) || View from behind the 1 m thick concrete shielding wall, showing the boron parafine used to absorb the neutrons (which are slowed down to thermal energies by 20 cm of parafine inside the boron parafine. The transport rail for the silver disk enters the parafine shielding from a whole in the concrete brick wall (not visible in the picture). || The RoboLab2 control computer, which is the server you connect to when running this exercise. ||
