Data Analysis

Once an experiment is complete, there are a variety of sorting codes on the gearbox account that can be used to view different aspects of the data generated.

Location of Data and Sort Codes

To begin, navigate to the directory where MIDAS saved the .mid files generated by the experiment run. When running the sort codes, the directory should always be set to the directory in which the .mid files are saved, and not the directory where the sort codes are located.

To view the available sort codes, navigate to the /home/gearbox/sort_GEARBOX/bin directory. The access path to gearbox sorting code should be enabled on login, therefore, the codes can be executed by typing the name of the code. By default, the code name without parameters should respond with the name of the code and required parameter list.

RADWARE

Analysis of spectra sorted by the codes above is enabledy by the RADWARE software package, modified to accommodate spectra from 16K ADCs. Frequently asked questions for RADWARE, are posted here while help on the gf3 spectrum analyzer is posted here. Help on gf3 is also accessible by the "help" command within a running gf3.

List of Sort Codes for verification of the data stream

Name	Parameters	Function	Output
GEARBOX_print_event	midas_input_data_file_name frequency	for a given midas file prints to screen data for event number divisible by frequency	screen printout
GEARBOX_deadtime	midas_input_data_file_name	for a given midas file computes deadtime correction based on trigger and clock data	screen printout
GEARBOX_count_zeros	midas_input_data_file_name	for a given midas file counts events with ADC readout of zero	screen printout
GEARBOX_event_rate	midas_input_data_file_name clock_pulse_per_time_unit	for a given midas file sorts spectrum of events per time unit defined by the clock_pulses_per_time_unit	root spectrum and GEARBOX_event_rate.spx RADWARE spectrum
GEARBOX_ts_diff	midas_input_data_file_name clock_pulse_per_time_unit	for a given midas file sorts spectrum of time stamp difference between consecutive events per time unit defined by the clock_pulses_per_time_unit parameter and conditioned on pileup events	root spectrum and GEARBOX_ts_diff.spx RADWARE spectrum with id=0 for no pileup and id=1 for pileup events
