Revision as of 00:03, 27 April 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

It is a 10 bit ADC

running at 250 MHz => 4 ns

[math]\frac{1V}{1024 \mbox{chan}} = 977 \frac{\mu \mbox{Volt}}{\mbox{chan}} \frac{1}{50 \Omega} 4 \times 10^{-9} s = 78 \frac{\mbox{fC}}{\mbox{chan}}[/math]

CAEN V792 was 100 \frac{\mbox{fC}}{\mbox{counts}}

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 # 4 at address 0x90bb0000 faInit: Enabling FADC Internal Clock, and Software Triggers (Soft Sync Reset) value = 0 = 0x0


Notice FADC ID is 0 in Slot 4 (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(4,1,40,38,3,6,1,0)


check using the status command 


-> faStatus(0)

ROC crashes

attempts

The FADC ussing block transfers of data so you need to install the DMA library

-> interrupt: faReadBlock: WARN: DMA transfer terminated by word count 0xfa0 interrupt: ERROR: Data still in FADC (event 5, scan 0x1 csr 0xf06318e7 ) - clearing


Trying 2.6.1/extensions

copied the file tempeDma/usrTempeDma.o

and loaded it onto my 6100 ROC 

ld < usrTempeDma.o

In my first attempt below I did not trigger the SIS3610 to readout so the FADC had more than 1 event in the FIFO. 


-> interrupt: ERROR: Data still in FADC (event 1, scan 0x2 csr 0xf06318ef ) - clearing

-> 0xdca6890 (ROC): memPartFree: invalid block 0xffffffff in partition 0x2ab41c.


on my second attempt I was more careful but go similar results 

interrupt: ERROR: NO data in FADC  datascan = 0x0
daLogMsg: INFO: active, events so far 1 token 0

-> 
-> interrupt: ERROR: Data still in FADC (event 4, scan 0x1 csr 0xf06318ef ) - clearing


On my 3rd attempt I sent only 1 trigger. Before sending the trigger I checked if there was and event using faStatus(0)

Set the FADC 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 =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 = 400 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
