Detailed Description

Event loop implementation.

Todo:

Analyse and display the hardware buffer overflow

Implementent a Katrin simulation module...

Implement cyclic reading of measure mode

Add user defined vaibales that are included in the result

Implemtent experiment specific analysis

Implement automatic error detection of the readout loop. Lost data, ... wide energy spread?! Test run with changing parameters to check stability. Is the spread of the energy histogramm small enough?

Add individual histogramm for every pixel

Todo:: Print result to file. The result should contain also other relevant data.

Member Function Documentation

void KaEventLoop::checkEvent ( KaEvent * ev )

Check if the ADC data is consistent.

In the interval [0..0x138] the data has to be around 100 In the interval [0x140 ..0x400] the data has to correspond to the energy level detected by the hardware

void KaEventLoop::displayEvent ( FILE * fout ) [virtual]

Display event.

Reimplemented from EventLoop.

void KaEventLoop::displayHeader ( FILE * fout ) [virtual]

Display header.

Reimplemented from EventLoop.

void KaEventLoop::displayHistogram	(	FILE *	fout,
		unsigned long *	hist,
		unsigned long	min,
		unsigned long	max
	)

Display histogram.

void KaEventLoop::displaySummary ( FILE * fout ) [virtual]

Display summary at the end of the run.

Reimplemented from EventLoop.

void KaEventLoop::getEnergyHwFilter	(	unsigned short *	data,
		int	len,
		int	n,
		int	thresh,
		unsigned long *	energy
	)

Re-implementation of the hardware energy filter.

Parameters:

data	ADC trace of 1024 values
len	Number of samples in the ADC trace
n	Filter length
thresh	Threshold
energy	Return value

void KaEventLoop::getEnergyMeanDiff	(	unsigned short *	data,
		int	len,
		int	n,
		unsigned long *	energy
	)

Implementation of a simple algorithm to determine the energy of the pulse.

The algorithm calculates the mean values of the intervals ped = [0x138-n, 0x138] and pulse = [0x140, 0x140+n]. The energy is calculated as energy = 8 * (pulse - ped).

Parameters:

data	ADC trace of 1024 values
len	Number of samples in the ADC trace
n	number of samples to calculate the mean values
energy	Return value

void KaEventLoop::getEnergyScaling	(	int *	min,
		int *	max
	)

Set energy histogramm scaling.

void KaEventLoop::getEnergyShortFilter	(	unsigned short *	data,
		int	len,
		int	n,
		int	thresh,
		unsigned long *	energy
	)

int KaEventLoop::getEvent ( FILE * fout ) [virtual]

Read events The algorithm returns only one event.

The order of the events in the FLTs is not checked. This means if two or more events occure at a time shorter than the loop sample time the events will be not in chronical order. The FLTs are always scanned in a consecutive manner starting with the column following the last event column.

Reimplemented from EventLoop.
