This page describes the experiment specific analysis that is conducted when running a particle decay spectroscopy experiment at the back of the RMS.
For an RMS experiment the following detector types and sub types are used.
- dssd_front - dssd_front - the front of the DSSD.
- dssd_back - dssd_back - the back of the DSSD.
- MCP - 1position1 - the first channel of the position sensitive MCP.
- MCP - 1position2 - the second channel of the position sensitive MCP.
- MCP - 1position3 - the third channel of the position sensitive MCP.
- MCP - 1position4 - the fourth channel of the position sensitive MCP.
- MCP - 1time - the timing signal of the position sensitive MCP.
- ge - clover - Clover detectors if used.
The multiplicities on the front and back of the DSSD are retrieved as are the maximum energies deposited in both the front and back and strip numbers where it occured. If both the energy deposited in the front and back is above a user defined threshold (variable ecutoff) then the event is treated as an implant. If both fron and back energies are below the cutoff the event is a decay. If one is a above and the other below the event is called an "unknown" type. The event is then correlated. If only the front or the back fires then the energy deposited into the DSSD is checked against ecutoff but the event is not correlated. If the mcp fired the position is determined from the four mcp signals.
All dssd plots (741, 742, 743, 744, 725, 726) are filled using the dssdplot function when either the front or back fires. The correlation time versus energy (the 750's) are plotted in the correlateplot function. The ge signals are plotted in the geplot function and the 2D mcp position spectra (923) is plotted in the mcp plot function.
