RMS

This page describes the experiment specific analysis that is conducted when running a particle decay spectroscopy experiment at the back of the RMS.

This section is unchanged and may not reflect what you would like to do.

Detector Types

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.

Event Processing

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 DssdProcessor::cutoffEnergy), then the event is treated as an implant. If both front 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 the cutoff energy but the event is not correlated. If the mcp fired the position is determined from the four mcp signals.

rms-Plotting

All dssd plots are filled using DssdProcessor::Process() when either the front or back fires. Ge signals are plotted in GeProcessor::Process() and the 2D mcp position spectra is plotted in McpProcessor::Process()
