FTPC Krypton Calibration Technical Study

To calibrate the amplification in the different electronics channels, we are planning to do a krypton calibration run: A radioactive krypton isotope is added to the chamber gas. The known energy deposit from electrons resulting from the gamma decay of the excited krypton state allows a calibration of the gas and electronics amplification, for a more precise measurement of the particle positions and their energy loss. The feasibility study was part of Tobias Eggert's diploma thesis.

An explanation of the krypton calibration and its planned use in the FTPC is in the transparencies to Tobias Eggert's talk at the Maria Laach Seminar [September 99]. Short cut: 1 2 3 4 5 6 7 8 9 10 11 12The Power Point file of these transparencies can be found under Documentation.
Some more documentation about the krypton project (in German) can be found on Tobias' homepage at the Technical University.
