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.

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

[math]\frac{1V}{2^{12} \mbox{chan}} = \frac{1V}{4096 \mbox{chan}} = 244 \frac{\mu \mbox{Volt}}{\mbox{chan}} \frac{1}{50 \Omega} 4 \times 10^{-9} s = 20 \frac{\mbox{fC}}{\mbox{chan}}[/math]

CAEN V792 was [math]100 \frac{\mbox{fC}}{\mbox{counts}}[/math]


The timing window can be as long as 4 [math]\mu[/math] 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

Software Trigger

Initialize FADC for software trigger mode

Initialize the FADC so it will accept software triggers.

faInit(0xbb0000,0,0,0)

-> faInit(0xbb0000,0,0,0) Initialized FADC 0 Slot # 7 at address 0x90bb0000 faInit: Enabling FADC Internal Clock, and Software Triggers (Soft Sync Reset) value = 0 = 0x0


Notice FADC ID is 0 in Slot 7 (the slots are number according to their location from the left most slot in the crate which starts counting at 1)

define processing mode

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

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 = latency = PL=20 => 200 nsec; time delay to record measurements after trigger is received and time window begins

PTW= 20 => 80 nsecPulse Time width = time interval window for measurements


Assuming the Clock is 250 MHz => clock pulse widths are 4 nsec

faSetProcMode(7,1,40,38,3,6,1,0)


check using the status command

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

Assuming the Clock is 250 MHz => clock pulse widths are 4 nsec

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)

I did not see any random triggers so I generated one.

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)
