Ethernet Data Aquisition Code for SIS3316 250MHz Digitizers

(Work in Progress) SimpleSetup.docx goes over the basic setup in more detail

Current Requirements

1. Python 3
2. Numpy

data_subscriber.py output dictionary values (unordered)

The dictionary fields depend on the hit/event flags that are set in the config file. Unless otherwise stated, all data types are 32-bit uint. The FIR Trigger shaper is the "short shaper" and the FIR Energy shaper is "long shaper".

Fields

0. rid - global event id number, useful for sorting raw data events
1. timestamp - 64-bit uint in samples (depends on clock frequency)
2. det - detector ID, first det is 0

if 'Accumulator Gates 1-6 Flag' is set to True then the following fields are also present

3. adc_max - max adc value .
4. adc_argmax - index of max value
5. pileup
6. gate 1
7. gate 2
8. gate 3
9. gate 4
10. gate 5
11. gate 6

if 'Accumulator Gates 7-8 Flag' is set to True

12. gate 7
13. gate 8

if 'MAW Values Flag' is set to True:

14. maw_max - max value of fast shaper
15. maw_after_trig - fast shaper value 1 sample after trig
16. maw_before_trig - fast shaper value 1 sample before trig

if 'Energy Values Flag' is set to True:

17. en_start - long shaper value at trigger
18. en_max - max value of long shaper

if 'Save MAW Signal' is set to True:

19. maw_data - 'MAW Test Buffer Length' of 32-bit uint Samples from either the short or long shaper. Energy/Long MAW if 'Save MAW Signal' is true, Trigger/Short MAW otherwise

if 'Sample Length' > 0

20. raw_data - 'Sample Length' 16-bit uint ADC samples

Notes

250 MHz -> 4 ns/sample
