Latest revision as of 21:14, 29 July 2011
JLab has built their own Flash ADC (called the F250)
It has a mini trigger connector which requires another VME board to convert from the standard lemo input to this mini input.
Properties
The 0.5 Volt setting has problems
The board I currently have is a 10 bit ADC but there is an internal shift making the value 12 bit. The lower bits are doubled up to do this.
running at 250 MHz => 4 ns
CAEN V792 was
The timing window can be as long as 4 sec.
The trigger must occur at least a few clock cycles after the pulse in order to capture all of the pulse in the window.
Addressing
JLab's F250 flash ADC will be used to measure the NaI output

Count events ready to be readout
you can count how many events or blocks are ready to be read out with the command
-> faDready(0,0) value = 1 = 0x1
try to read a block
I stil don't see channel 1 or 3 in the output?

RUn 2144 with 64 events
Run 2145 with
faChanDisable
One can disable ADC channels using the function
faChanDisable(ID,mask)
where mask is a word representing which channels you should disable with the high bit.
all 16 channels are disables with 0xffff
only channel 0 is enabled with
faChanDidable(0,0xfffe)

clearing the module and downloading everything again seemed to make the problem go away. Also power cycling the VME crate as well.
- It also seems to help if you do software triggers.
more DMA error
I am having trouble getting some configurations working without a DMA error.
for example
- The smallest process configuration always has a DMA error
faSetProcMode(7,1,2,1,0,0,0,0)
The smallest one I was able to get working without a DMA error was
faSetProcMode(7,1,20,8,0,0,0,0)
I do see the error
interrupt: ERROR: Data still in FADC (event 1039, scan 0x1 csr 0xf06318ef ) - clearing
about every 1000 +/- 500 events.
See runs 2141 and 2142
Now I increase the latency to 200 (800 ns).
Long run 2143 was taken.
Extra words
Extra data words are appearing in the FADC bank written to the CODA data file.
Configure ADC for NaI readout
The NaI detector signal width can be as much a 4 micro seconds.
That is a lot of samples
The JLab PMT output has a signal width of about 1 microsecond
Let configure the FADC to take raw samples for 2 microseconds.
You will need a latency time to determine where the window should begin since a discriminator is used to generate the ADC gate based on the NAI output. This means the ADC trigger is some time after the pulse. THis is OK because the FADC is always sampling the input in a using a time window you define.
Lets define a time window which is 2 microseconds long.
Since the clock is 250 MHz, this means each time bin is 4 ns. A timing window with 500, 4 ns bins will sum to 2 microseconds.
Set timing window
int faSetProcMode(int id, int pmode, unsigned int PL, unsigned int PTW, unsigned int NSB, unsigned int NSA, unsigned int NP, int bank) id = slot number =7 An example of this should be in one of the Readout lists, however, right now there are 3 viable processing modes (pmode =1,2 or 3) pmode = 1 RAW Window mode: all samples within PTW are saved pmode = 2 RAW Pulse mode: NSA+NSB+1 samples around a threshold crossing are saved. pmode = 3 Integral pulse mode: NSA+NSB+1 samples are summed and the sum along with the timestmp for the threshold crossing are saved. PL = 40 = 160 ns = programmable latency ; time delay to record measurements after trigger is received and time window begins PTW= 20 => 80 nsecPulse Time width = time interval window for measurements = number of samples in the pulse time window moving forward in time from the location of the latency. NSB = 3 = Number of Samples before before the pulse to record NSA=6 = number of samples after the pulse to record NP =1 = number of pulses to look for in the PTW
faSetProcMode(7,1,540,500,0,0,0,0)
