PHYS-C0310 - Teknillisen fysiikan laboratoriotyöt, Luento-opetus, 24.10.2022-23.4.2023

Exercise content: 

The energy spectrum of gamma radiation and the non-idealities in the spectrum due to measurement and measuring devices are studied in this work. The work also determines the energies of unknown gamma quanta of one substance. Various radioactive isotopes are used for this as a source of different energy gamma quanta. The measuring equipment consists of a scintillation detector and a digital pulse analyzer.

Schedule

Exercise reservation list can be found from this link.

The reports will be returned to the assistant by email. The reports should be written only in English.

The exercise is carried out at the physics student laboratory U027, which is located at the basement of the Otakaari 1 U-segment. You can come to the lab for example through the M-entry (take a right turn and down the stairs).

Material and measurements

Read carefully job-related material (theory and work instructions), where more references can be found. Also read carefully "Completing the course" and "Report writing instructions". Before starting the measurements the assistant will ask preliminary questions to make sure that the students have sufficient background knowledge to perform the measurements. Both members of the working group must master the central material, although only one of the students will write the report. Be prepared to make notes during the measurements with pen and paper or by some other means. If you cannot come to your reserved exercise session, please inform the assistant in due time and make a new appointment with the assistant.

To prepare yourself for the measurements, we also provide the following video demonstrations. Find them below.
