All files are ascii, approximately 5 MBytes in length (runs 1-18) and 18MBytes (runs 19-26).

Note: the scalers are not reset, but accumulate through the experiment.



 

NASA-JSC Data

During the week of 13-15 October 2008, we ran Iron and Protons for two experiments from NASA-JSC.  The data acquisition was operated in two different configurations, labeled below as either Scaler or Spectrum/Timing.  When running in the Scaler mode, we accumulated the number of beam particles that passed through the two beam counting scintillators during a 4 second beam spill.  The scintillators had cross sectional area of 1.08 cm2 and 10.28 cm2, respectively.  During the runs, the small scintillator was upstream of the large scintillator.  Both were placed slightly above (~1cm) and downstream (~20cm) of the two JSC detectors.

In order to record the beam intensity to compare with the dosimetry, we operated in Scaler mode where scalers counted the number of beam particles seen by each scintillator, as well as counting a 10kHz clock pulse, and the number of beam spills.  These counts are accumulated in a scaler that is not resetting.  The scaler is read out once per spill (every 4 seconds), and the spill counter should increment with each record.  The files have a time stamp at the beginning and end of each file. 

Iron ion running is described first. 

When running in Scaler mode (runs 1-2), the event record has the following format:

Word Number 1 2 3 4 5
Word Type Scaler Scaler Scaler Scaler TDC
Description 10 kHz
Clock
Small Scintilator Large
Scintillator
Spill Counter Ignore

In order to study the performance of the proportional counter, we split the signal with a passive splitter.  Half of the signal was differentiated using a pass-through capacitor into a discriminator operating at a -10 mV threshold.  The other half of the signal was delayed (~2 microseconds in cables) and sent to a Peak Sensing ADC (CAEN V785) for digitising.  This allowed us to get a look at the spectrum online. 

When running in Spectrum/Timing mode (runs 3-11), the event record has the following format:

Word Number 1 2 3 4
Word Type Scaler Scaler ADC TDC
Description 10 kHz
Clock
Spill Counter Proportional Counter Ignore

 We also ran in a Timing only mode (runs 12-14) where no ADC information was taken, to study the distribution of Proportional Chamber triggers throughout the 300 millisecond long beam spill.  Both Word #1 and Word #3 are the 10 kHz clock pulse, but in Word #3 the scaler is reset at the beginning of every 4 second spill cycle.

The event record for Timing only runs has the following format:

Word Number 1 2 3 4
Word Type Scaler Scaler Scaler (Reset each spill) TDC
Description 10 kHz
Clock
Spill
Counter
10 kHz
Clock
Ignore

For runs 15-17 we read out both the scaler and ADC.  The event record has the following format:


Word Number 1 2 3 4 5
Word Type Scaler Scaler ADC Scaler TDC
Description 10 kHz
Clock
Spill
Counter
Detector 10 kHz
Clock

For runs 18-24 we added the scaler counts for the small and large scintillator to the event record. 

Word Number 1 2 3 4 5 6 7
Word Type Scaler Scaler Scaler Scaler ADC Scaler TDC
Description 10 kHz Clock Small Scint Large Scint Spill Counter Detector 10 kHz Clock Ignore

Although the event record was the same for runs 18-24, the mode of data taking was not.  In runs 18, 23 and 24 we were triggered by the Proportional Chamber for spectral measurements and event rate studies.  In Runs 19-22 the scalers were read out only once per spill in order to allow for comparison with the dosimetry results.

Proton running is described second.

For the proton running, the data format for all runs (except H_1000_15_10_2008_004.txt) is described as follows:

Word Number 1 2 3 4 5 6
Word Type Scaler Scaler Scaler Scaler Scaler TDC
Description 10 kHz
clock

Scint
Small

Coincidence Spill
Counter

One proton run was taken to measure the pulse height spectrum and timing distribution (run 4).   It was read out whenever the Proportional Counter had a hit that passed a Discriminator Threshold.  This run had the following format:

 
Word Number 1 2 3 4 5 6 7 8
Word Type Scaler Scaler Scaler Scaler Scaler ADC Scaler TDC
Description 10 kHz
